Ask a Therapist: Bite Block Speech Sounds



I am an SLP who attended the "A Three-Part Treatment Plan for Oral Placement Therapy" workshop. I would like to find out if there is a set of speech sounds corresponding to the jaw height for Bite Blocks? For example, Bite Block #7 corresponds to "ah" vowel. 



My name is Monica Purdy and I am a TalkTools Instructor and teach the mentioned course.  I just wanted to answer your questions regarding the sounds that go with the bite blocks.

Bite blocks 2 and 3 work on the high position of the jaw and address the following sounds:  m,b,p,f,v,n,s,z,sh,ch and r  and the following vowels:  I (as in big), e (as in me), u (as in blue).

Bite blocks 4 and 5 address the medium position of the jaw and work on following sounds:  "th" voiced and voiceless, l, t and d and the following vowels:  uh, o, a (as in ball), e (as in bed).

Bite blocks 6 and 7 work on the low position of the jaw and address the following sounds:  g,k, and h  and following vowels:  a (as in mad) and a (as in ahh).

I hope this helps, please let me know if you have any further questions.

    Hi , I teach are class on lisps. If the child is under 7, I recommend that you refer to Sara Rosenfeld Johnson’s book OPT for /s/ and /z/ . If the child is over 7, I suggest you look at my SMILE Program. In these cases, most often there is a lack of tongue retraction with tip dissociation, and often there are myofunctional challenges such as a tongue thrust. If you do not treat the swallow , the speech lags behind. The tools you have are all excellent, but without considering the three part approach that includes sensory-motor and feeding, it is often challenging to make progress. Hope that helps !
