Articulatory and physiological classification of speech sounds
Мета:to find out about articulatory and physiological features of speech sounds.
Короткі теоретичні відомості
Auditory phonetics (аудитивна фонетика) studies the perceptual response to speech sounds, as mediated by ear, auditory nerve and brain, i.e. its interests lie more in the sensation of hearing, which is brain activity, than in the psychological working of the ear or the nervous activity between the ear and the brain. The means by which we discriminate sounds – quality, sensations of pitch, loudness, length, are relevant here.
Before analysing the linguistic function of phonetic units we need to know how the vocal mechanismacts in producing oral speechand what methods are applied in investigating the material form of the language, that is its substance.
Human speech is the result of a highly complicated series of events. The formation of the concept takes place at a linguistic level, that is in the brain of the speaker; this stage may be called psychological. The message formed within the brain, is transmitted along the nervous system to the speech organs. Therefore we may say that the human brain controls the behaviour of the articulating organs which effects in producing a particular pattern of speech sounds. This second stage may be called physiological.The movements of the speech apparatus disturb the air stream thus producing sound waves. Consequently the third stage may be called physical or acoustic.Further, any communication requires a listener, as well as a speaker. So the last stages are the receptionof the sound waves by the listener's hearing physiological apparatus, the transmissionof the spoken message through the nervous system to the brain and the linguistic interpretation of the information conveyed.
Articulatory phonetics borders with anatomy and physiology and the tools for investigating just what the speech organs do are tools which are used in these fields: direct observation, wherever it is possible, e.g. lip movement, some tongue movement; combined with X-ray photography or X-ray cinematography; observation through mirrors as in the laryngoscopic investigation of vocal cord movement, etc.
