BACKGROUND
Ultrasound has shown promise as visual feedback in remediation of /r/.
AIMS
To compare treatment for /r/ with and without ultrasound.
METHODS & PROCEDURES: A Canadian English-speaking adolescent participated in a case study with a no treatment baseline, alternating treatment blocks with and without ultrasound and a final no treatment period.
OUTCOMES & RESULTS: Formant values and trained listener ratings of speech samples indicated improvement in /r/ production, particularly after the introduction of ultrasound.
CONCLUSIONS
Ultrasound appeared to facilitate the acquisition of /r/ for the participant. Large-scale studies are needed to evaluate ultrasound further.
背景
超声已显示出有望作为/r/音矫治中的视觉反馈手段。
目的
比较有无超声辅助的/r/音治疗效果。
方法与过程
一名说加拿大英语的青少年参与了一项案例研究，研究包括无治疗基线期、有无超声辅助的交替治疗阶段以及最后的无治疗期。
结果与结论
语音样本的共振峰数值及经过训练的听众评分表明，/r/音的发音有改善，尤其是在引入超声之后。
结论
超声似乎有助于该参与者习得/r/音。需要开展大规模研究以进一步评估超声的作用。
