29 Teaching /tʃ/ with Teeth Tapping and Airflow
Amarri Rogers
Guided Practice Script
Hello! Today we are going to be practicing the /tʃ/ sound! This sound is heard at the beginning of the word chew and at the end of the word peach. Peaches are really yummy fruits, so let’s start by saying that word. Repeat after me, okay, “peach”. [1] Great!
For this sound today, let’s pull out Mr. Mouth and my trusty mirror! Okay, look at Mr. Mouth, do you see how I am lifting the middle of his tongue to touch the top of his mouth? Awesome, now I want you to try doing that yourself in the mirror. [2] Wow, great job!
Do you remember when we were practicing the /ʃ/ sound? You do great! Well, I have good news /tʃ/ is close to /ʃ/! Now that you have your mouth in that place, I want you to close and open your teeth, not your lips.[3] I know a little confusing here, watch me. Okay, now you. Great try! Now try to add a big puff of air with each closing of your teeth, watch me now you try. That was a good try!”
Target Techniques and Considerations
Elicitation techniques
- Modeling
- Phonetic Placement
- Facilitating Context
Common /tʃ/ Sound Errors
- /t/ is sometimes substituted for /tʃ/. Why? /tʃ/ is a stop plus an affricate which can be difficult for some children, so instead of both some children just produce the stop /t/.
Accent or Dialect Variations
- People who speak Korean or Japanese as their first language may experience native language transfer, for example, substituting “tsu” for chew.
