The speech of 14 stutterers was analyzed prior to and at the termination of a 5-week stuttering therapy program to examine the relationship between nine selected acoustic variables and stuttering frequency. Group analyses indicated that pre- to post-therapy changes in stuttering frequency were accompanied by mean changes in five of the nine acoustic variables, a finding which is consistent with previous literature. Correlational analyses indicated that only silence in the voiced stop consonant intervocalic interval (IVI) was significantly correlated with stuttering frequency prior to therapy (i.e., lower stuttering frequency values were associated with shorter durations of silence during the IVI). Furthermore, the degree of reduction in silence was positively correlated with the magnitude of reduction in stuttering frequency due to therapy. These findings suggest that silence in the IVI may reflect the operational status of some mechanism which may underlie disfluent speech.
在一项为期5周的口吃治疗项目开始前及结束时，对14名口吃者的言语进行了分析，以研究九个选定的声学变量与口吃频率之间的关系。组分析表明，治疗前后口吃频率的变化伴随着九个声学变量中五个变量的平均变化，这一发现与先前的文献一致。相关分析表明，只有浊音塞音元音间隔（IVI）中的沉默与治疗前的口吃频率显著相关（即，较低的口吃频率值与IVI期间较短的沉默持续时间相关）。此外，沉默减少的程度与治疗引起的口吃频率降低幅度呈正相关。这些发现表明，IVI中的沉默可能反映了一些可能是言语不流畅基础的机制的运行状态。
