physiology of speech production

Speech itself is air that is moved from the lungs through a series of anatomic structures that mold sound waves into intelligible speech. there are three functional areas 32. The resonators produce a person’s recognizable voice. Through the resonance of the vocal tract, the glottal sound is modified so that some frequency components are amplified and others are attenuated. The Anatomy and Physiology of Speech Production(Phonetics) 1. Anatomy and Physiology of Speech Production. Koyama T, Kawasaki M, Ogura JH, Louis SM (1969) Mechanics of voice production. Normal voice production relies on three things: A power source (lungs) A vibrating source (vocal folds, or larynx) Anatomy to modify the sound (throat, mouth, tongue, lips and) teeth; The lungs expel air through the voice box cause the vocal folds to vibrate. Speech production at the peripheral level consists of three stages: exhalation, phonation, and articulation (Table 2.1). In: Daniloff RG (ed) Speech science.

Perkell, unknown edition, The data would also interest engineers concerned with speech simulation by computer. The “spoken word” results from three components of voice production: voiced sound, resonance, and articulation. Over 10 million scientific documents at your fingertips. Authors Nina Dronkers, Jennifer Ogar. This section deals with what is involved in the production of speech sounds and which organs or parts of the body play a role in it. The quality of the sounds produced depends on the force and volume of air pushed from the lungs to the vocal cords.

Unformatted text preview: ANATOMY AND PHYSIOLOGY OF SPEECH PRODUCTION COMPONENTS OF SPEECH Respiration Phonation Resonance Articulation RESPIRATION Muscles of the thorax particularly the Diaphragm contract to cause the lungs to expand or compress The flow of air is from areas of high pressure to low pressure The lungs naturally collapse and are held open by negative pressure between … The air flow is cut into puffs (alternating current) at the closed glottis as the vocal cords vibrate. The following processes are involved in speech production. Dr Mike explains how speech is produced in the cortex and transmitted to the muscles of articulation (words) and phonation (sound).

Voiced sound: The basic sound produced by vocal fold vibration is called “voiced sound.” This is frequently described as a “buzzy” sound.

An extensive study of articulatory motions is clearly presented with carefully organized and detailed quantitative data derived from tracings of a lateral cineradiography. providing air for speech production. The monograph also gives some analysis and interpretation of the data in terms of underlying linguistic categories. Pract Oto 21: 425–450, van den Berg Jw, Tan TS (1959) Results of experiments with human laryngEs. The third stage of speech production is articulation, which is the execution of the articulatory score by the lungs, glottis, larynx, tongue, lips, jaw and other parts of the vocal apparatus resulting in speech.

ROLE IN SPEECH PRODUCTION Broca’s Area is a part of the brain particularly notable for its involvement in speech. This system includes the throat and the larynx, which is actually quite complicated. Session: The Physiology of Speech Phonetics and Phonology 7 2 Session: The Physiology of Speech In order to develop an understanding for speech sounds it is important to work out where and how they are produced. However, it will be useful to begin our discussion of the source–filter theory of speech production by considering voiced sounds in which the larynx produces a periodic source. Speaking is in essence the by-product of a necessary bodily process, the expulsion from the lungs of air charged with carbon dioxide after it has fulfilled its function in respiration. An electromyographic investigation of some laryngeal muscles. Resonance: Voice sound is amplified and modified by the vocal tract resonators (the throat, mouth cavity, and nasal passages). Movement of the entire lower jaw can alter the size of the mouth cavern and influence the tone and volume of the speech. Exhalatory movement of the respiratory organ provides the subglottal air flow (direct current). It makes a passive contribution to speech production by forming part of the length of suraglottal vocal tract, but its geometry and volume can also be adjusted to vary this contribution or for other articulatory effects.
