Types of Phonetics & Phonetic Symbols

Introduction

Phonetics is an important branch of linguistics. It studies speech sounds. Human language is mainly spoken, so sounds are the base of communication. Phonetics helps us understand how these sounds are made, how they travel, and how people hear them. It does not study spelling or writing. It studies only sounds. This is very helpful in learning and teaching languages, especially English, where spelling and pronunciation are often different.

What is Phonetics?

Phonetics is the study of speech sounds. It tells us how sounds are produced by the human body, how they move in the air, and how they are heard by the ear and understood by the brain.

In simple words, phonetics studies:

• how sounds are produced
• how sounds travel
• how sounds are heard and understood

Phonetics does not study meaning or grammar. It studies only pronunciation. For example:

• cat → /kæt/
• phone → /fəʊn/
• think → /θɪŋk/

These are not spellings, but sound forms. English spelling is often confusing. Words like though, through, and tough look similar but sound different. Phonetics helps to remove this confusion.

Types (Branches) of Phonetics

Phonetics has three main branches:

1. Articulatory Phonetics

This branch studies how sounds are made by the speech organs. These organs are lungs, vocal cords, tongue, lips, teeth, palate, and nose.

It explains:

• how vowels and consonants are produced
• which organs are used in making sounds
• whether a sound is voiced or voiceless

For example, /p/ is made without voice and /b/ is made with voice. This branch is useful for learning correct pronunciation.

2. Acoustic Phonetics

This branch studies sounds as sound waves. It explains how sounds travel in the air.

It studies:

• loudness of sound
• pitch of sound
• quality of sound

This branch uses machines and technology to study sounds. It is useful in language labs, speech technology, and voice recording systems.

3. Auditory Phonetics

This branch studies how sounds are heard and understood.

It explains:

• how the ear receives sound
• how the brain understands sound
• how people पहचान (recognize) different sounds

It is useful in language learning, speech therapy, and hearing studies.

Phonetic Symbols

Phonetic symbols are special signs used to show speech sounds. Each symbol shows one sound. The most important system of phonetic symbols is the International Phonetic Alphabet (IPA). Phonetics symbols (International Phonetic Alphabets) were first created in 1888 by various British linguists.

Importance of Phonetic Symbols

Phonetic symbols:

• help in correct pronunciation
• remove spelling confusion
• help students and teachers
• are used in dictionaries
• help in speech training
• are useful in linguistics

Conclusion

Phonetics is the study of speech sounds. It helps us understand how sounds are made, how they travel, and how they are heard. The three branches of phonetics are articulatory, acoustic, and auditory phonetics. Phonetic symbols, especially IPA symbols, help us write correct pronunciation. Phonetics is very useful for students, teachers, language learners, and speakers of English.
