Methods of Phonetic Investigation

Methods applied in investigating the sound matter of the language have changed greatly with the development of technology and computer science. From the beginning of phonetics the phonetician has relied mainly on what he could feel of his own speech and on what he could hear both of his own and the informant’s speech. Such methods are called direct and consist in observing the movements and positions of one's own or other people's organs of speech in pronouncing various speech sounds, as well as in analysing one's own kinaesthetic sensations (muscle tense) during the articulation of speech sounds and in comparing them with the resultant auditory impressions. Investigation by means of this method can be effective only if the persons employing it have been specially trained and have acquired considerable skills in associating the qualities of the perceived sound with the nature of the articulations producing it.

Instrumental methods were introduced into phonetics in the last century to supplement the impressions deriving from the human senses. These methods are based upon registering or computing machines and technical devices, such as spectrograph, intonograph, x-ray photography and cinematography, laryngoscope and some others. The introduction of machines for measurements and for instrumental analysis into phonetics has resulted in their use for detailed study of many of the phenomena which are present in the sound wave or in the articulatory process at any given moment. These techniques can be very useful both for discovering in detail how English speakers produce their speech sounds, and for demonstrating to learners of English their pronunciation. Computers can provide additional pronunciation training, displaying useful information on the screen and being a powerful visual aid for effective phonetic practice. One more advantage of the modern experimental study of speech is the enormous amount of varied spoken speech data stored on computers. It facilitates the process of looking for cross-language differences and similarities. The data obtained from instrumental analysis supplement and verify those obtained by means of direct observation, thus making the research results more detailed and precise.
