What is Phonetics?

 

Phonetics is the study of the physical properties of speech sounds and how they are produced, transmitted, and perceived. It examines the physical properties of speech sounds such as their acoustic characteristics, the way they are produced in the vocal tract, and the physiological processes involved in speech production. It also considers the perception of speech sounds and how they are understood by listeners.

Phonetics can be divided into two main branches: articulatory phonetics, which deals with how speech sounds are produced by the vocal tract, and auditory phonetics, which deals with how speech sounds are perceived by the ear and brain.

Articulatory phonetics examines the movement and positioning of the vocal organs such as the tongue, lips, and larynx, in the production of speech sounds, and classifies speech sounds based on their articulatory properties. Auditory phonetics, on the other hand, examines the acoustic properties of speech sounds such as frequency and duration, and how they are perceived by the ear and brain.

Phonetics is essential for understanding the nature of speech sounds and how they are used in different languages, and also for the fields such as speech pathology, speech synthesis, and speech recognition.

Key Terms

• Articulatory, acoustic and auditory phonetics: the three branches: how sounds are made, how they travel as sound waves, and how they are heard.
• IPA: the International Phonetic Alphabet, one symbol for each sound, used in learner dictionaries.
• Place and manner of articulation: where and how the air is blocked: /p/ is made with both lips (bilabial) and a complete stop (plosive).
• Voicing: whether the vocal cords vibrate: /b/ is voiced, /p/ is voiceless.

An Example

Say fan and van with a finger on your throat. The lips and teeth are in the same position for /f/ and /v/; the only difference is the vibration you feel for /v/. Phonetics describes sounds at this level of physical detail.

Why It Matters for Teachers

Bangla-speaking learners often replace English /z/ with a sound like /dʒ/ (so zoo sounds like Jew) and may not separate /v/ from /b/ or /bʱ/. Showing students where the tongue and lips should be, and teaching them to read IPA in a dictionary, gives them a way to correct pronunciation on their own.
