Unit 4.1
Sound: CH
Introduction
The digraph ch represents a velar sound.
Form
The sound of ch is:
| Uppercase | Lowercase | Phonetics |
|---|---|---|
| CH | ch | /k/ |
Example
ch: schedule, scheme, school.
Use
To pronounce the digraph ch the articulation is the same of the letter c. The back of the tongue is pressed against the soft palate, forming a barrier. When a stream breaks through this obstacle, sound is produced.
- ch: voiceless, vocal cords do not vibrate during the articulation
LAURA
Ch is a digraph because two letters represent only one sound, in this case, /k/. To articulate it, the tip of the tongue is pressed against the soft palate, forming a barrier that will be broken by the stream of air, producing the sound. This procedure is the same as in letter c, another velar consonant, as both represent the same sound.
- ch is voiceless, so the vocal cords do not vibrate during the articulation.
