2. PHONETICS
• Phonetics may be defined as the science of speech. It is
concerned with all aspects of the production, transmission, and
perception of the sounds of language.
• Example :- lips, tongue and teeth, to produce particular
3. AREAS OF PHONETICS
• Accordingly, there are three branches of Phonetics,
namely, Articulatory Phonetics, Acoustic Phonetics and Auditory
Phonetics. All the three branches together give us crucial
information about speech sounds.
4. ARTICULATORY PHONETIC
• Articulatory phonetics is the branch of phonetics concerned with describing the speech sounds of the
world's languages in terms of their articulations, that is, the movements and/or positions of the vocal
organs (articulators).
• Examples:-
• Lips. We use lips in the production of numerous consonant sounds. ...
• Teeth. When we say words with the sound of t, y, f, and v, we need to use our teeth to create sounds. ...
• Tongue. Tongue is one of the most important organs, and it plays a major role in sound production. ...
• Nasal Cavity.
5. ACOUSTIC PHONETIC
• Acoustic phonetics is the study of the acoustic characteristics of speech,
including an analysis and description of speech in terms of its physical
properties, such as frequency, intensity, and duration.
• Following are some examples where we can hear how the acoustic
phonetics sounds: Human voices. Whale sounds. Wind.
6. AUDITORY PHONETIC
• Auditory phonetics is the branch of phonetics concerned with the hearing of speech
sounds and with speech perception.
• Examples:
• Communication between humans.
• Sirine.
• Listening based test.
• Horn.
