研究概览
简要总结
Previous research suggests that biofeedback can outperform traditional interventions for RSE, but no controlled studies have tested this hypothesis in the context of app-delivered biofeedback. The objective of this aim is to use the staRt app to test our working hypothesis that speakers will make larger gains in /r/ accuracy when app-based treatment incorporates biofeedback, compared to a non-biofeedback condition. With a network of cooperating SLPs, this project will recruit 15 children with /r/ misarticulation to receive 8 weeks of intervention using staRt. Individual sessions will be randomly assigned to include or exclude the visual biofeedback display. Randomization tests will be used to evaluate, for each individual, whether larger increments of change are associated with biofeedback and non-biofeedback sessions.

结局指标
主要结局
F3-F2 Distance, an Acoustic Measure That Correlates With Perceptual Accuracy of /r/, Measured From /r/ Sounds Produced in Treatment Sessions.
时间窗: F3-F2 distance was measured in all 16 treatment sessions (eight of each type), which were administered over eight weeks.
From recordings of words containing /r/ produced during treatment sessions, the sound /r/ was flagged for measurement and the first three formants (F1, F2, F3) were extracted from the center of the /r/ interval. The distance between the second and third formants (F3-F2) was used as the index of rhoticity. F3-F2 is small in perceptually accurate /r/, larger values indicate lower accuracy. Summary statistics report the mean and standard deviation of normalized F3-F2 distance for each treatment condition, pooled across participants and sessions. A two-tailed paired-samples t-test (superiority criterion) was used to compare mean F3-F2 distance for each treatment condition across subjects.
