1.1 Definition of speech, characteristics of normal speech and functions of speech
Speech communication is using oral mediums to pass a message from a speaker to the listeners in formal and informal situations. Leaders often use this form of communication to interact with their followers at events, including award ceremonies, business conferences, political campaigns, weddings, and funerals.
Speech communication refers to the use of the oral medium of passing information, whether formally or informally, by a speaker to an audience. The information could be a speaker's way to be understood on a topic, building an argument, and evoking emotions among the audience. This type of communication is instrumental to public speaking as it enhances engagement with a live audience regarding a specific topic or a set of topics. Therefore, speech communication is useful in delivering real-time communication to a live audience.
People could use speech communication on occasions such as weddings, funerals, political rallies, award ceremonies, and business meetings to initiate and advance discussions and arguments on topics related to the events. Speech communication is common in leaders interacting with their followers at companies and even administrative units. It helps them leverage their position to pass a message to the audience.
Speech is how we say sounds and words. Speech includes:
Articulation
How we make speech sounds using the mouth, lips, and tongue. For example, we
need to be able to say the r sound to say "rabbit" instead of
"wabbit.
Voice
How we use our vocal folds and breath to make sounds. Our voice
can be loud or soft or high- or low-pitched. We can hurt our voice by talking
too much, yelling, or coughing a lot.
Fluency
This is the rhythm of our speech. We sometimes repeat sounds or pause while
talking. People who do this a lot may stutter.
Physical properties of speech
Speech is a kind of physical movement, so it has physical properties. The physical properties of speech refers to the physical properties of speech, also known as the natural properties of speech.
From the perspective of production, speech is generated by the vibration of the articulatory body and transmitted through the medium, and the most important medium for the transmission of sound is air.
Speech is divided into noise and music, where vowels are music and consonants are noise. Speech is a unity of pitch, intensity, duration and timbre. Any actual phonetic unit is a unity of these four elements.
Physiological properties of speech
The physiological attribute of speech refers to the fact that speech is produced by human vocal organs, and the difference of speech units is caused by the difference of vocal organs. Different sounds have different meanings, and the human vocal apparatus can be divided into three parts according to its role in speech formation:
Social properties of speech
The social attribute of speech refers to the social nature of speech. Speech has a certain meaning and plays a communicative role as the carrier of meaning, which determines that speech has social attributes. This is also the most fundamental property that distinguishes speech from other sounds in nature, so the social attribute is the essential attribute of speech. The social attributes of speech are manifested in many aspects, such as the connection between sound and meaning, national and local characteristics, and the systematization of speech.
Common Speech Functions
Functions of speech are different ways of communicating. The differences among the speech functions have to do with the intention of the communication. Different intention or goal leads to the use of a different function of speech. There are many different functions if speech but we will look at the six that are listed below.
Referential
Referential speech provides information. For example, a person might share the
time with someone ( It s five o clock ). Referential speech can often provide
information to a question ( what time is it? ).
Directive
Directives or commands that try to get someone to do something. Examples include turn left or sit down . The context of a directive is one in which something needs or should be done. As such, one person tries to make one or more other persons do something. Even children say directives towards their parents ( give me the ball ).
Expressive
Expressive speech shares a person s feelings. An example would be I feel happy today! . Expressive communication can at times provide clear evidence of how someone is doing.
Phatic
Phatic speech is closely related to expressive speech. However, the main difference is that phatic speech is focused on the well-being of others while expressive speech focuses on the feelings of the person speaking.
An example of phatic speech is saying how are you? . This is clearly a question but it is focusing on how the person is doing. Another phrase might be I hope you get well soon. Again the focus on is on the welfare of someone else.
Poetic
Poetic speech is speech that is highly aesthetic. Songs and poetry are examples of language that is poetic in nature. An example would be the famous nursery rhyme Roses are red, violets are blue ..). Poetic speech often has a powerful emotional effect as well.
Metalinguistic
Metalinguistic speech is communication about language. For example, this entire blog post would be considered by many to be metalinguistic because I a talking about language and not really using language as described in the other functions of speech.
Exceptions
There are many more categories than the ones presented. In addition, the categories presented are not mutually exclusive. Many phrases can be correctly classified into many different categories. For example, if someone says I love you you could argue that it s expressive, poetic, and or even phatic. What is missing is the context in which such a statement is made.
1.2 Parameters of speech
The parameters of speech refer to the various aspects or characteristics that make up the production and perception of spoken language. These parameters encompass the physical and cognitive processes involved in speaking and understanding speech, as well as the different features that distinguish how speech sounds are made and how they are perceived by listeners.
Key Parameters of Speech
1. Articulation: Articulation refers to the movement of the speech organs (such as the tongue, lips, teeth, and vocal cords) to produce sounds.
o Place of Articulation: Where in the vocal tract the airflow is restricted, such as the lips (bilabial sounds like "b" and "p") or between the teeth (dental sounds like "th").
o Manner of Articulation: How the airflow is constricted, such as a stop (complete closure like in "t"), a fricative (narrow constriction like in "f"), or a nasal (air passes through the nose like in "m").
o Voicing: Whether the vocal cords vibrate during the production of the sound (e.g., "b" is voiced, while "p" is voiceless).
2. Pitch: Pitch is the perceived frequency of sound, which determines how high or low a voice sounds.
o Fundamental Frequency: The base rate of vibration of the vocal cords, affecting the perceived pitch.
o Intonation: The rise and fall in pitch across speech. Intonation patterns convey emotions, questions, or statements (e.g., a rising pitch often indicates a question).
3. Loudness: Loudness refers to the perceived volume of speech.
o Intensity: The physical amplitude of the sound waves produced by the speaker.
o Stress: The emphasis placed on certain words or syllables, often making them louder or more forceful.
4. Duration: Duration refers to the length of time a speech sound is held.
o Speech Rate: How fast or slow someone speaks.
o Vowel and Consonant Length: Some languages use long or short vowels and consonants to distinguish meaning (e.g., Japanese "biru" for "beer" vs. "biiru" for "building").
5. Voice Quality: Voice quality refers to the unique characteristics of a person's voice, such as its timbre, which makes it distinguishable from others.
o Breathiness: When air escapes through the vocal cords during speech, producing a soft or airy voice.
o Harshness: When the voice sounds strained or rough due to excessive tension in the vocal cords.
o Hoarseness: A raspy, often weak voice caused by vocal cord issues.
6. Rhythm: Rhythm refers to the pattern of speech sounds in time, including the pace and timing of syllables, words, and phrases.
o Stress Timing: The pattern in which stressed and unstressed syllables occur in speech. English, for example, is stress-timed, meaning the rhythm is based on the intervals between stressed syllables.
o Syllable Timing: In languages like French, speech tends to be syllable-timed, meaning the rhythm is based on the regularity of syllables rather than stress.
7. Resonance: Resonance refers to the amplification and modification of sound as it travels through the vocal tract, including the throat, mouth, and nasal passages.
o Oral vs. Nasal Resonance: Sounds may be resonated primarily in the mouth (oral sounds) or through the nose (nasal sounds like "m" or "n").
o Hypernasality: When too much sound resonates through the nasal passages, often due to a cleft palate or other structural issues.
8. Fluency: Fluency refers to the smoothness and flow of speech without interruptions or hesitations.
o Pauses: Brief stops or breaks during speech that help with meaning or phrasing.
o Stuttering: A disruption in the normal flow of speech, characterized by repetitions, prolongations, or blocks of sounds.
9. Clarity: Clarity refers to how easily speech can be understood by listeners.
o Articulatory Precision: How clearly speech sounds are formed, making them easily distinguishable.
o Coarticulation: How adjacent sounds affect each other (e.g., how the "k" sound in "cat" differs from the "k" in "kit").
10.Stress: Stress refers to the emphasis placed on certain syllables or words in speech.
Additional Speech Parameters
In speech production, these parameters articulation, pitch, loudness, duration, voice quality, rhythm, resonance, fluency, clarity, and stress work together to create clear, expressive, and meaningful communication. These features can be influenced by a variety of factors, including individual differences in vocal anatomy, language development, emotional state, and cultural or linguistic background.
1.3 Mechanism of speech production structure and function of Respiratory, Phonatory, Articulatory, Resonatory and Regulatory system
Speech is such a common aspect of human existence that its complexity is often overlooked in day to day life. Speech is the result of many interlinked intricate processes that need to be performed with precision. Speech production is an area of interest not only for language learners, language teachers, and linguists but also people working in varied domains of knowledge. The term speech refers to the human ability to articulate thoughts in an audible form. It also refers to the formal one sided discourse delivered by an individual, on a particular topic to be heard by an audience.
Speech Mechanism
Speech mechanism is a function which starts in the brain, moves through the biological processes of respiration, phonation and articulation to produce sounds. These sounds are received and perceived through biological and neurological processes. The lungs are the primary organs involved in the respiratory stage, the larynx is involved in the phonation stage and the organs in the mouth are involved in the articulatory stage.
The Brain
The brain plays a very important role in speech. Research on the human brain has led to identification of certain areas that are classically associated with speech. In 1861, French physician Pierre Paul Broca discovered that a particular portion of the frontal lobe governed speech production. This area has been named after him and is known as Broca s area. Injury to this area is known to cause speech loss. In 1874, German neuropsychiatrist Carl Wernicke discovered that a particular area in the brain was responsible for speech comprehension and remembrance of words and images. At a time when brain was considered to be a single organ, Wernicke demonstrated that the brain did not function as a single organ but as a multi pronged organ with distinctive functions interconnected with neural networks. His most important contribution was the discovery that brain function was dependent on these neural networks. Today it is widely accepted that areas of the brain that are associated with speech are linked to each other through complex network of neurons and this network is mostly established after birth, through life experience, over a period of time.
The organs of speech
In order to understand speech mechanism one needs to identify the organs used to produce speech. It is interesting to note that each of these organs has a unique life-function to perform. Their presence in the human body is not for speech production but for other primary bodily functions. In addition to primary physiological functions, these organs participate in the production of speech. Hence speech is said to be the overlaid function of these organs. The organs of speech can be classified according to their position and function.
1. The respiratory process involves the movement of air. Through muscle action of the lungs the air is compressed and pushed up to pass through the respiratory tract- trachea, larynx, pharynx, oral cavity, nasal cavity or both. While breathing in, the rib cage is expanded, the thoracic capacity is enlarged and lung volume is increased. Consequently, the air pressure in lungs drops down and the air is drawn into the lungs. While breathing out, the rib cage is contracted, the thoracic capacity is diminished and lung volume is decreased. Consequently, the air pressure in the lungs exceeds the outside pressure and air is released from the lungs to equalize it. Once the air enters the pharynx, it can be expelled either through the oral passage, or through the nasal passage or through both depending upon the position of soft movable part of the roof of the mouth known as soft palate or velum.
Egressive and Ingressive Airstream: If the direction of the airstream is inward, it is termed as Ingressive airstream. If the direction of the airstream is outward, it is Egressive airstream . Most languages of the world make use of Pulmonic Egressive airstream. Ingressive airstream is associated with Scandinavian languages of Northern Europe. However, no language can claim to use exclusively Ingressive or Egressive airstreams. While most languages of the world use predominantly Egressive airstreams, they are also known to use Ingressive airstreams in different situations.
Egressive process involves outward expulsion of air. Ingressive process involves inward intake of air. Egressive and Ingressive airstreams can be pulmonic (involving lungs) or non-pulmonic (involving other organs).
Non Pulmonic Airstreams: There are many languages which make use of non pulmonic airstream. In these cases the air expelled from the lungs is manipulated either in the pharyngeal cavity, or in the vocal tract, or in the oral cavity. Three major non pulmonic airstreams are:
In Ejectives, the air is trapped and compressed in the pharyngeal cavity by an obstruction in the mouth with simultaneous closure of the glottis. The larynx makes an upward movement which coincides with the removal of the obstruction causing the air to be released.
In Implosives, the air is trapped and compressed in the pharyngeal cavity by an obstruction in the mouth with simultaneous closure of the glottis. The larynx makes a downward movement which coincides with the removal of the obstruction causing the air to be sucked into the vocal tract.
In Clicks, the air is trapped and compressed in the oral cavity by lowering of the soft palate or velum and simultaneous closure of the mouth. Sudden opening causes air to be sucked in making a clicking sound.
While the process of phonation occurs before the airstream enters the oral or nasal cavity, the quality of speech is also determined by the state of the pharynx. Any irregularity in the pharynx leads to modification in speech quality.
2. The Phonatory Process: Inside the larynx are two membrane-like structures or folds called the vocal cords. The space between these is called the glottis. The vocal folds can be moved to varied distance. Robert Mannel has described five main positions of the vocal folds:
Voiceless: In this position the vocal folds are drawn far apart so that the air stream passes without any interference.
Breathy: Vocal folds are drawn loosely apart. The air passes making whisper like sound Voiced: Vocal folds are drawn close and are stretched. The air passes making vibrating sound.
Creaky: The vocal folds are drawn close & vibrate with maximum tension. Air passes making rough creaky sound. This sound is called vocal fry and its use is on the rise amongst urban young women. However its sustained and habitual use is harmful.
3. Resonatory System
Resonance: Amplifying the Sound
The sound produced in the larynx travels through the pharynx, oral cavity, and nasal cavity, where resonance occurs. This amplification process adds richness and depth to the speech sounds.
The resonatory system provides the voice with its distinct quality, and it is why we all sound different from each other. The resonatory system is made up of the open spaces within the throat, mouth, and nose, so you can think of the resonatory system as an open space. The sound that is made at the level of the vocal cords is only a buzzing sound, and we all sound very similar to each other at this level. However, as that buzzing sound travels up through the resonatory system, it bounces from one surface to the next. Certain frequencies are enhanced, and other frequencies are dampened, and the end result is our unique-sounding voice. If you open your mouth and say ahh! , you will hear an example of your unique voice - a pure vowel tone.
4. Articulatory System
The Mouth The mouth is the major site for articulatory processes of speech production. It contains active articulators that can move and take different positions such as the tongue, the lips, the soft palate. There are passive articulators that cannot move but combine with the active articulators to produce speech. The teeth, the teeth ridge or the alveolar ridge, and the hard palate are the passive articulators.
Amongst the active articulators, the tongue can take the maximum number of positions and combinations to. Being an active muscle, its parts can be lowered or raised. The tongue is a major articulator in the production of vowel sounds. Position of the tongue determines the acoustics in the oral cavity during articulation of vowel sounds. For the purpose of identifying and describing articulatory processes, the tongue has been classified on two parameters.
a. The part of the tongue that is raised during the articulation process. There are four markers to classify the height to which the tongue is raised
b. The height to which the tongue is raised during the articulation process. Three main parts of the tongue are identified as Front, Back, and Center.
For the purpose of description the positions of the tongue are diagrammatically represented through the tongue quadrilateral.
The tongue also acts as an active articulator on the roof of the mouth to create obstruction in the oral cavity.
Lips: The lips are two strong muscles. In speech production the movement of the upper lip is less than that of the lower lip. The lips take different shapes: Rounded, Neutral or Spread
Teeth: The Upper Teeth are Passive Articulators.
The roof of the mouth:
The roof of the mouth has a hard portion and a soft portion which are fused seamlessly. The hard portion comprises of the Alveolar Ridge and the Hard Palate. The soft portion comprises of the Velum and the Uvula. The anterior part of the roof of the mouth is hard and unmovable. It begins from the irregular surface called alveolar ridge which lies behind the upper teeth. The alveolar ridge is followed by the hard palate which extends up to the centre of the tongue. The posterior part of the roof of the mouth is soft and movable. It lies after the hard palate and extends up to the small structure called the uvula.
The soft palate: It is movable and can take different positions during speech production.
The hard palate lies between the alveolar ridge and velum. It is a hard and unmovable part of the roof of the mouth. It lies opposite to the centre of the tongue and acts as a passive articulator against the tongue to produce sounds. Sounds produced with the involvement of the hard palate are called palatal sounds.
The alveolar ridge is the wavy part that lies just behind the teeth ridge opposite to the front of the tongue. It acts as a passive articulator against the tongue to produce sounds. Sounds produced with the involvement of the Alveolar ridge are called Alveolar sounds. Some sounds are created with the involvement of the posterior region of the Alveolar ridge. These sounds are called post alveolar sounds. Sometimes sounds are created with the involvement of the hindmost part of the alveolar ridge and the foremost part of the hard palate. Such sounds are called palato alveolar sounds.
Air stream mechanisms involved in speech production
The flow of air or the airstream is manipulated in a number of ways during production of speech. This is done with the movement of the active articulators in the oral cavity or the larynx. In this process the air stream plays a major role in the production of speech sound. Air stream works on the concept of air pressure. If the air pressure inside the mouth is greater than the pressure in the atmosphere, air will escape outward to create a balance. If the air pressure inside the mouth is lower than the pressure outside because of expansion of the oral or pharyngeal cavity, the air will move inward into the mouth to create balance. On the basis of the nature of the obstruction and manner of release, the following classification has been made:
Plosive: In this process there is full closure of the passage followed by sudden release of air. The air is compressed and when the articulators are suddenly removed the air in the mouth escapes with an explosive sound.
Affricate: In this process there is full closure of the passage followed by slow release of air.
Fricative: In this process the closure is not complete. The articulators come together to create a narrow passage. Air is compressed to pass through this narrow stricture so that air escapes with audible friction.
Nasal: The soft palate is lowered so that the oral cavity is closed. Air passes through the nasal passage creating nasal sounds. If the soft palate is partially lowered air passes simultaneously through the oral and nasal passages creating the nasalized version of sounds. Lateral: The obstruction in the mouth is such that the air is free to pass on both sides of the obstruction.
Glide: The position of the articulators undergoes change during the articulation process. It begins with the articulators taking one position and then smoothly moving to another position.
5. Regulatory system
Regulatory System
Regulation: The Role of the Brain and Nervous System
The brain plays a pivotal role in controlling and coordinating the speech mechanism.
Broca s Area: The Seat of Speech Production
Located in the left frontal lobe, Broca s area is responsible for speech production and motor planning for speech movements.
Wernicke s Area: Understanding Spoken Language
Found in the left temporal lobe, Wernicke s area is crucial for understanding spoken language and processing its meaning.
Arcuate Fasciculus: Connecting Broca s and Wernicke s Areas
The arcuate fasciculus is a bundle of nerve fibers that connects Broca s and Wernicke s areas, facilitating communication between speech production and comprehension centers.
Motor Cortex: Executing Speech Movements
The motor cortex controls the muscles involved in speech production, translating neural signals into precise motor movements.
1.4 Speech as an overlaid function
According to Sapir, 1921 physiologically, speech is an overlaid function, or to be more precise, a group of overlaid functions. It gets what service it can out of organs and functions, nervous and muscular, that have come into being and are maintained for very different ends than its own.

Speech is considered as an overlaid function because the primary function of the organs involved in speech production is not speech! For example Larynx is just a valve to prevent foreign bodies from entering the trachea and its primary function is not speech. The same applies for all the other organs of speech production. Therefore speech is considered as overlaid function.
Speech makes use of existing physiological systems that evolved for other purposes, such as breathing, swallowing, and vocalizing, to perform the specialized task of verbal communication. Essentially, speech is built on top of (or overlays) these basic functions, rather than being a completely separate or independent biological function.
1.5 Introduction to Speech and Language Disabilities
Speech and language disabilities refer to a range of conditions that affect a person's ability to communicate effectively. These disabilities can impact both the production of speech and the comprehension or use of language, leading to challenges in social, educational, and professional settings.
Here are some common types of speech and language disabilities:
1. Speech Disabilities
These disabilities affect the physical production of speech sounds.
Common Types of Speech Disabilities
a) Articulation Disorders: These disorders involve difficulty pronouncing sounds correctly. A person with an articulation disorder may substitute one sound for another, omit sounds, or distort sounds when speaking.
o Example: Saying "wabbit" instead of "rabbit" or "thun" instead of "sun."
b) Fluency Disorders: These disorders affect the flow of speech, often resulting in disruptions such as stuttering. People with fluency disorders may repeat words, syllables, or sounds, or experience long pauses in speech.
o Example: Stuttering (repetition of sounds or syllables, such as "I...I...I want to go").
c) Voice Disorders: These affect the pitch, volume, or quality of the voice. A person may have a voice that sounds hoarse, breathy, strained, or overly soft. This can be caused by physical issues with the vocal cords or improper voice use.
o Example: A person who speaks in a very raspy or whispery voice, or who has difficulty projecting their voice.
d) Apraxia of Speech: Apraxia is a motor speech disorder where the brain has difficulty coordinating the muscle movements needed to make speech sounds. This results in difficulty pronouncing words, even though the person knows what they want to say.
o Example: A person might know the word they want to say, but they might say "pa" instead of "cat."
e) Dysarthria: Dysarthria is a speech disorder caused by weakness or lack of coordination in the muscles that are used for speech. It often results from neurological conditions such as stroke, cerebral palsy, or Parkinson's disease.
o Example: Speech that sounds slurred or difficult to understand because of weakened or paralyzed muscles involved in speech production.
f) Speech Delay: A speech delay refers to a condition where a child develops speech and language skills later than expected. Children with speech delays may have difficulty pronouncing words, using correct grammar, or speaking in full sentences. Some children catch up with age-appropriate speech and language skills, while others may need therapy to catch up.
2. Language Disabilities
These disabilities affect a person's ability to understand, use, or process language. They can involve problems with vocabulary, grammar, or sentence structure.
Common Types of Language Disabilities
a) Receptive Language Disorder: Receptive language disorder involves difficulty understanding language. This means a person may have trouble following directions, understanding questions, or grasping the meaning of spoken or written words.
o Example: A child may struggle to understand the difference between "above" and "below" or may have trouble following a simple instruction like "Put the book on the table."
b) Expressive Language Disorder: Expressive language disorder is characterized by difficulty using language to express thoughts, ideas, or feelings. This can involve problems with vocabulary, sentence structure, grammar, or the ability to convey clear messages.
o Example: A person might say "I goed to the store" instead of "I went to the store," or they might use limited vocabulary and have trouble forming complete sentences.
c) Mixed Receptive-Expressive Language Disorder: This disorder involves difficulties with both understanding and using language. It s a combination of receptive and expressive language issues, and individuals with this disorder may have trouble both understanding what others say and conveying their own thoughts effectively.
o Example: A child may not understand what is being asked of them and may also struggle to express themselves clearly, using incomplete or incorrect sentences.
d) Aphasia: Aphasia is a condition that affects language skills, often caused by brain damage due to stroke, injury, or neurological disorders. It can involve difficulty speaking, understanding speech, reading, or writing. The severity and specific areas of language affected depend on the location and extent of brain damage.
o Example: A person with aphasia might have trouble finding the right words (anomia), forming sentences (agrammatism), or understanding complex sentences or spoken words.
e) Auditory Processing Disorder (APD): APD refers to a difficulty in processing and interpreting sounds, despite normal hearing. People with APD have trouble understanding speech, especially in noisy environments, even though their hearing abilities may be normal.
o Example: A person may have difficulty distinguishing between similar sounds (like "pat" vs. "bat") or understanding speech in a crowded room.
f) Specific Language Impairment (SLI): SLI, also known as Developmental Language Disorder (DLD), is a condition where children experience language delays that are not caused by other developmental issues, such as hearing loss or intellectual disabilities. It may affect vocabulary, grammar, and sentence structure.
o Example: A child with SLI may have trouble with word endings (e.g., "-ed" in "walked") or may have a limited vocabulary for their age.
g) Social (Pragmatic) Communication Disorder: This disorder involves difficulties with the social aspects of communication, including understanding and using language in socially appropriate ways. It may affect the ability to take turns in conversation, interpret nonverbal cues, or understand the context of communication.
o Example: A person may have difficulty with sarcasm or jokes, struggle to maintain eye contact during a conversation, or have trouble starting or ending conversations appropriately.
Causes of Speech and Language Disabilities
Speech and language disabilities can arise from various causes, including:
Treatment and Support
Treatment often involves working with professionals like speech-language pathologists (SLPs) who can assess, diagnose, and create treatment plans tailored to the individual's needs. Interventions can include:
Impact on Daily Life
People with speech and language disabilities may face challenges in various aspects of life:
The key to supporting people with speech and language disabilities is early identification, personalized treatment plans, and understanding from others in social and professional contexts.
