Evaluation of influence of CD, FID and OD on speech.

Perceptual analysis of speech (using rating by one SLP)
- More speech problems in the experimental group compared with the
Runte et al. (2001)
Evaluation of influence of the position of the upper incisives on the /s/ sound.
n: 20 12 8
Spectral analysis of speech
- There was less energy in the /s/sound in the situations 2 and 3.
- A labial direction evoked a lower frequency, a palatal direction evoked

control group. Especially with the /s/-/z/ and /t/-/d/. Analysis of oromyofunction
No differences between the two groups.
n4: (FID/FID): 15
Questionnaire satisfaction
- No change of satisfaction with speech before and after treatment.
- No difference between the control group and the experimental group.
