Speech Work : Consonant sounds - JSS1 English Language Lesson Note

Introduction to Consonant Sounds

Consonant sounds are an essential part of spoken language. They are produced by obstructing or restricting the airflow through the vocal tract. Here's an introduction to consonant sounds:

Definition:

Consonant sounds are speech sounds produced by constricting or obstructing airflow using various parts of the mouth, such as the lips, tongue, teeth, and palate.

2. Types of Consonants:

-Voiced Consonants : Produced with vibration of the vocal cords, such as /b/, /d/, /g/.
   Voiceless Consonants : Produced without vibration of the vocal cords, such as /p/, /t/, /k/.
   - Nasal Consonants:  Produced by lowering the velum to allow air to pass through the nose, such as /m/, /n/, /ŋ/.
   - Fricative Consonants : Produced by forcing air through a narrow channel, creating friction, such as /f/, /s/, /ʃ/.
   - Stop Consonants: Produced by completely obstructing the airflow, then releasing it, such as /p/, /t/, /k/.

3. Articulation :  Consonant sounds are articulated by manipulating the airflow using specific articulators, such as the lips, tongue, and teeth. For example, the sound /b/ is produced by closing the lips and then releasing them to let out a burst of air.

4. Examples: Here are some examples of consonant sounds:
   - /b/ as in "bat"
   - /d/ as in "dog"
   - /f/ as in "fish"
   - /s/ as in "snake"
   - /m/ as in "moon"
   - /tʃ/ as in "chair"
   - /ŋ/ as in "sing"
   - /h/ as in "hat"

5. Importance: Understanding and mastering consonant sounds is crucial for clear and effective communication. They form the building blocks of words and enable us to convey meaning accurately.

By familiarizing yourself with consonant sounds and practicing their articulation, you can improve your pronunciation and communication skills in English.
