简要总结
This research will meet a public health need by evaluating the efficacy of speech intervention supplemented with real-time visual-acoustic biofeedback when delivered using remote technologies.
详细描述
In a crossover design, participants will be randomly assigned to receive 10 weeks/20 sessions of visual-acoustic biofeedback treatment via telepractice followed by a 10-week period of no treatment, or the same two conditions in the reverse order. Production accuracy will be assessed with standard probes (20 syllables, 30 words, and 10 sentences containing /r/ in various phonetic contexts) administered prior to the beginning of treatment (baseline), after the first 10-week phase, and again at the end of the study.

盲法说明
All perceptual ratings will be obtained from blinded, skilled clinician listeners recruited through online crowdsourcing. Following protocols refined in previous published research, binary rating responses (1=correct; 0=incorrect) will be aggregated over at least 9 unique listeners per token.

研究组 & 干预措施
Visual-Acoustic Biofeedback Treatment via Telepractice Followed by No Treatment
Condition1: Treatment phase followed by no-treatment
Children with RSE and typical perception will be allocated to a randomized controlled trial measuring the efficacy of online visual-acoustic biofeedback treatment. Twenty children with RSE will receive 10 weeks of visual-acoustic biofeedback training via video call.

结局指标
主要结局
Rhotic Accuracy (/r/)
时间窗: BL - (Initial Assessments:1-2 weeks), MP-(Midpoint assessment -1 day following First Period (10 weeks), MN - (Maintenance Assessment -1 day following Second Period (10 weeks).
To evaluate the generalization of treatment effects to untreated words, participants will complete standardized word probes comprising 50 target words. The primary outcome measure is the proportion of words rated as "correct" across all tokens, reflecting perceptual accuracy of the participant's responses.
次要结局
- Change in Social-emotional Well-being(Survey completed at BL ( evaluation) and MN ( 1 day following Second period duration). Same for both groups.)
