目的：最近的研究表明，视听生物反馈可以有效地治疗残余语音错误，但由于成本高和缺乏对技术的熟悉等障碍，采用仍然有限。这个案例研究报告的结果，从第一个参与者完成一个过程中的视觉-声学生物反馈使用一个不以营利为目的的iOS应用程序，语音治疗师的应用程序/r/ Treatment.Method：基于应用程序的生物反馈治疗的发音错误提供了每周30分钟的会议，为20周。使用临床感知评级和声学测量记录治疗内进展。泛化收益进行了评估，使用声学措施的字探针引起的基线，治疗，和maintenance sessions.Results：两个临床医生的评级和声学措施表明，参与者显着提高了她的rhotic生产的准确性，在治疗过程中引起的试验。然而，这些收益并没有转移到泛化probes.Conclusions：这项研究提供了一个概念验证的演示，基于应用程序的生物反馈是一个可行的替代昂贵的专用系统。在没有生物反馈的情况下推广收益仍然是一个挑战，需要进一步研究。应用程序提供的生物反馈可以使临床医生研究伙伴关系，这将加强证据基础，同时为残留的旋转错误儿童提供更好的治疗。
Purpose: Recent research suggests that visual-acoustic biofeedback can be an effective treatment for residual speech errors, but adoption remains limited due to barriers including high cost and lack of familiarity with the technology. This case study reports results from the first participant to complete a course of visual-acoustic biofeedback using a not-for-profit iOS app, Speech Therapist's App for /r/ Treatment.Method: App-based biofeedback treatment for rhotic misarticulation was provided in weekly 30-min sessions for 20 weeks. Within-treatment progress was documented using clinician perceptual ratings and acoustic measures. Generalization gains were assessed using acoustic measures of word probes elicited during baseline, treatment, and maintenance sessions.Results: Both clinician ratings and acoustic measures indicated that the participant significantly improved her rhotic production accuracy in trials elicited during treatment sessions. However, these gains did not transfer to generalization probes.Conclusions: This study provides a proof-of-concept demonstration that app-based biofeedback is a viable alternative to costlier dedicated systems. Generalization of gains to contexts without biofeedback remains a challenge that requires further study. App-delivered biofeedback could enable clinician-research partnerships that would strengthen the evidence base while providing enhanced treatment for children with residual rhotic errors.
