A new parameter, the area under the speech envelop, was used to evaluate the degree of speech dysfluency in stutterers. This parameter has been measured for 100-s utterances of 30 fluent speakers and 30 stutterers speaking with simultaneous auditory feedback (SAF) and delayed auditory feedback (DAF). A correlation was found between the area under the speech envelope and the severity of stuttering. Thus for stutterers, this parameter can be used to evaluate the degree of the disturbance of fluency. The values of this parameter were significantly higher in fluent utterances than in nonfluent ones. The reduction of stuttering observed in stutterers under DAF was accompanied by an increase of the area under the speech envelope, making it comparable to the one measured for the utterances of fluent speakers.
一个新的参数，即语音包络下的面积，被用于评估口吃者的言语不流畅程度。已针对30名流利说话者和30名口吃者在同时听觉反馈（SAF）和延迟听觉反馈（DAF）条件下的100秒话语测量了该参数。发现语音包络下的面积与口吃严重程度之间存在相关性。因此，对于口吃者来说，该参数可用于评估流畅性障碍的程度。该参数在流利话语中的值显著高于不流利话语中的值。口吃者在延迟听觉反馈条件下观察到的口吃减少伴随着语音包络下面积的增加，使其与流利说话者话语测量值相当。
