Lee Silverman Voice Treatment (LSVT) has well-documented treatment efficacy for individuals with hypokinetic dysarthria associated with Parkinson's disease (PD). Positive changes have been noted after treatment not only for vocal loudness but also for many other speech dimensions, including intonation (monotonicity). There have been few studies investigating the effect of LSVT on lexical tone which, like intonation, is controlled by variations in fundamental frequency. This study involved 12 Cantonese speakers with idiopathic PD who were enrolled in a standard LVST treatment protocol. Speech data were collected 3-4 days before treatment and 1 day after treatment. A wide variety of perceptual and acoustic variables were analyzed. The results showed significant improvements in loudness and intonation after treatment, but no significant changes in lexical tone. These results have theoretical implications for the relationship between tone and intonation and for models of the physiological control of fundamental frequency.
李·西尔弗曼嗓音治疗（LSVT）在治疗帕金森病（PD）相关运动迟缓性构音障碍方面具有良好的疗效记录。治疗后不仅可以改善声音的响亮程度，还可以改善许多其他言语维度，包括语调（单调）。很少有研究调查 LSVT 对声调的影响，而声调与语调一样，是由基频的变化控制的。这项研究涉及 12 名患有特发性帕金森病的粤语使用者，他们参加了标准的 LSVT 治疗方案。在治疗前 3-4 天和治疗后 1 天收集语音数据。分析了各种感知和声学变量。结果表明，治疗后音量和语调显著改善，但声调无显著变化。这些结果对声调与语调的关系以及基频生理控制模型具有理论意义。
