Experimental Phonetics

Stage 2: Articulatory phonetic
Although most techniques are expensive and difficult to use, but they 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 errors in a way that helps them to correct them. For example, recording the airflow from speaker’s speaker’ mouths can show how successfully they are producing the aspiration appropriate for p, t, and k.
(1) Recently developed, safer X-ray techniques can help Xus to observe articulatory movements taking place within the vocal tract, and contact between the tongue and the palate can be measured electrically. (2) It is also possible to detect the electrical activity that is produced when muscles contract, and we can thus observe the complex co-ordination of activity in the comuscles controlling speech production.

What is Experimental Phonetics?
Experimental phonetics is the branch of general phonetics that deals with the study of the sounds and other human speech units applying the experimental method. This scientific field covers basic areas of phonetics articulatory phonetics, acoustic phonetics and auditory phonetics.

Experimental Phonetics
Experimental phonetics has been an important part of phonetics for almost century, and experimental work in phonetics laboratories has produced many important discoveries about how speech is produced and perceived. There is a hope that in coming years the fields of pronunciation teaching and of experimental phonetics will become much more closely linked.
Stage 3: Acoustic phonetic
Acoustic phonetic the study of the physical
transmission of speech sounds from the speaker to the listener
Recently, it is possible to get an accurate computer analysis of the fundamental frequency of speech , and it is also possible to get a computer to produce a simple phonetic transcription of what is said to it. If such techniques are further developed, it should be possible to use computers to provide additional pronunciation training at times when a human teacher is not available.
Stage 4、5：Auditory phonetic 4、
Auditory phonetic: the study of the reception and phonetic: perception of speech sounds by the listener. It is of great importance to discover more about how the listener’s brain identifies what it receives from ear, listener’ the experimental phonetics has made much use of speech produced by machines called speech synthesisers. It is possible that synthetic speech may have a useful role to play in testing language learner’s ability to learner’ perceive important segmental and suprasegmental distinctions in the language they are learning.
