I recently had a client that was struggling with the /t/ and /d/ sounds and realized I have not yet covered these on Mommy Speech Therapy, so I thought I’d share some thoughts on how to teach these sounds. I have grouped these sounds together because they are produced in the same manner and place. The only difference between the /t/ and /d/ sounds is the /d/ sound is voiced while the /t/ sound is not. If your child can produce a /t/ sound and not the /d/ sound you simply teach them to “turn on their voice” for the /d/ sound. Or if it is the other way around you teach them to “turn off their voice” by whispering the sound for the /t/.
