Full eligibility criteria
Inclusion Criteria: * Medical diagnosis of cerebral palsy, or a similar, related condition that affects early motor development and presents as a chronic motor disability * Age between 7 and 17 years * Clinical dysarthria with speech intelligibility between 10-85 percent * Able to produce connected speech in English, with a minimum utterance length of 3 words * Able to use hands to point to items on a communication board * Cognitive/language skills that enable basic picture identification on a communication board * Pass pure tone hearing screening Exclusion Criteria: * Failure to meet all inclusion criteria. * Vision impairment that precludes being able to see items on a communication board. * Not suitable for participation due to other reasons at the discretion of the investigators.
About the study
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
