简要总结
The goal of this randomized-controlled trial is to determine how artificial intelligence-assisted home practice may enhance speech learning of the "r" sound in school-age children with residual speech sound disorders. All child participants will receive 1 speech lesson per week, via telepractice, for 5 weeks with a human speech-language clinician. Some participants will receive 3 speech sessions per week with an Artificial Intelligence (AI)-clinician during the same 5 weeks as the human clinician sessions (CONCURRENT treatment order group), whereas others will receive 3 speech sessions per week with an AI-clinician after the human clinician sessions end (SEQUENTIAL treatment order group.
详细描述
Artificial Intelligence-assisted treatment that detects mispronunciations within an evidence-based motor learning framework could increase access to sufficiently intense, efficacious treatment despite provider shortages. A successful Artificial intelligencesystem that can predict the clinical gold standard of trained listeners' perceptions could not only improve access to clinical care but also mitigate known confounds to accurate clinical feedback, including clinical experience and drift due to increasing familiarity between the speaker and listener. The Artificial intelligence tool used in this study includes a speech classifier trained to predict clinician judgment of American English "r" that is integrated into an existing evidence-based treatment software called Speech Motor Chaining.

盲法说明
All perceptual ratings will be obtained from trained listeners who are blinded to treatment group and to timepoint. Binary rating of accuracy of the "r" sound (i.e., judgments of correct or incorrect) will be obtained from three listeners per token.

结局指标
主要结局
Change in percent correct for the /ɹ/ sound in untreated words, rated by blinded listeners.
时间窗: Before the initiation of treatment and again 5 weeks later.
To assess generalization of treatment gains to untreated words, participants will read a word list eliciting /ɹ/. Stimuli in each list will be presented individually in randomized order. Individual words will be isolated from the audio record of each word probe and presented in randomized order for perceptual rating by trained listeners who are blind to treatment condition and time point (but will see the written representation of each target word). We will use the change in percent correct as our primary measure of perceptually rated accuracy.
次要结局
- Survey evaluating impacts of speech disorder on participants' social, emotional, and academic well-being.(Before the initiation of treatment and again 5 weeks later.)
- Change in percent correct for the /ɹ/ sound in untreated words, rated by blinded listeners.(After 5 weeks of treatment and again 10 weeks later.)
- Change in percent correct for the /ɹ/ sound in practiced words, rated by blinded listeners.(After 5 weeks of treatment and again 10 weeks later.)
- Retention of percent correct for the /ɹ/ sound in untreated words, rated by blinded listeners.(Before the initiation of treatment and again 10 weeks later.)
- Change in percent correct for the /ɹ/ sound in practiced words, rated by blinded listeners.(Before the initiation of treatment and again 5 weeks later.)
- Change in percent correct for the /ɹ/ sound in practiced words, rated by blinded listeners.(Before the initiation of treatment and again 10 weeks later.)
