本质上是语音的语音错误的治疗程度(即,失真)对未训练的声音产生泛化作用。本案例研究报告了一名儿童,该儿童被转介治疗美式英语//,他还表现出/l/的不一致的线性失真。声学分析显示,在治疗前,//和/l/之间存在隐蔽的对比。超声生物反馈治疗和知觉训练有针对性//仅,但跟踪//和/l/的进度。观察到两种声音在感知上的准确性和声学特征的显着变化方面的显着改善,表明泛化。这些结果突出表明,对于具有以语音失真为特征的残余语音错误的儿童,可以从训练到未训练的声音进行概括。
The extent to which treatment of speech errors that are phonetic in nature (i.e., distortions) produces generalization to untrained sounds is not well understood. This
case study
reports a child referred for treatment of a velarized distortion of American English /ɹ/, who also demonstrated an inconsistent velarized distortion of /l/. Acoustic analysis revealed evidence of a covert contrast between /ɹ/ and /l/ prior to treatment. Ultrasound biofeedback treatment and perceptual training targeted /ɹ/ only, but progress was tracked for both /ɹ/ and /l/. Substantial improvements in perceptually rated accuracy and significant changes in acoustic features were observed for both sounds, indicating generalization. These results highlight that generalization from trained to untrained sounds is possible for children with residual speech errors characterized by phonetic distortions.
