  • Intelligibility, Speech

Age
7 Years - 17 Years
Healthy Volunteers

Interventions

  • AAC Speech supplementation — BEHAVIORAL
    The speech supplementation intervention involves learning to point to pictures, words, or letters on a communication board while simultaneously producing speech. Children will spend up to 30 minutes learning to use the strategy in one- on-one interaction with a speech therapist and demonstrate mastery by using the strategy successfully on a series of test stimuli.

Study Details

The goal of this clinical trial is to learn if speech supplementation can improve speech intelligibility in children ages 7 to 17 years with cerebral palsy. The main questions it aims to answer are: * To what extent can speech supplementation improve intelligibility in children with CP compared with habitual speech produced without speech supplementation? * How much intelligibility change is necessary for meaningful improvement when children use speech supplementation strategies? Participants will: * complete speech and language assessments * complete a speech pre-test using habitual speech * learn a speech supplementation strategy with training from a speech-language pathologist * complete a speech post-test using the speech supplementation strategy * complete a speech repetition task where specific words are emphasized (emphatic stress) * use the previously learned speech supplementation strategy + emphasis on specific words while producing a set of sentences
