This work deals with the duration of voicing and silence periods of continuous speech in rooms with very different reverberation times (RTs). Measurements were conducted using the Ambulatory Phonation Monitoring (APM) 3200 (Kaypentax, Montvale, NJ) and Voice-Care devices (developed at the Politecnico di Torino, Italy), both of which have a contact microphone placed on the base of the neck to detect skin vibrations during phonation. Six university professors and 22 university students made short laboratory monologs in which they explained something that they knew well to a listener 6 m away. Seven students also described a map with the intention of correctly explaining directions to a listener who drew the path on a blank chart. Longer speech samples were made by 25 primary school teachers in classrooms. A tendency to increase the voicing periods as the RT increased was on average observed for the university professors, the school teachers, and the university students who described a map. These students also showed longer silence periods than the students who made short monologs. The recognized trends concerned voice professionals or subjects who were highly motivated to make themselves understood in a perturbed speaking situation. Nonparametric statistical tests, which were applied to detect the differences in distributions of voicing and silence periods, have basically supported the findings.
这项工作研究了在混响时间（RT）差异极大的房间中连续语音的发声时长和静音时长。测量使用了动态发声监测仪（APM）3200（Kaypentax公司，新泽西州蒙特瓦尔）和语音护理设备（由意大利都灵理工大学研发），这两种设备都有一个置于颈部底部的接触式麦克风，用于检测发声时的皮肤振动。六位大学教授和22名大学生进行了简短的实验室独白，他们向6米外的听众解释自己熟知的事物。七名学生还描述了一幅地图，目的是向在空白图表上绘制路线的听众正确说明方向。25名小学教师在教室里录制了更长的语音样本。对于大学教授、学校教师以及描述地图的大学生，平均而言，随着混响时间增加，发声时长有增加的趋势。这些学生的静音时长也比进行简短独白的学生更长。所识别出的趋势涉及语音专业人士或在受干扰的说话情境中有强烈意愿让自己被理解的受试者。用于检测发声和静音时长分布差异的非参数统计检验基本支持了这些发现。
