Mandibular displacement during /s/ production was monitored via a mercury strain gauge which was taped to the face of two normally articulating and six /s/-misarticulating children. Simultaneous audio and jaw displacement visicorder traces were produced from an FM-tape recording of each experimental session, and were subsequently analyzed. Results indicated that various /s/-misarticulating subgroups exhibit different mandibular positions during /s/-production, and phonetic contextual effects upon mandibular position also vary by articulatory type.
通过粘贴在两名正常发音和六名/s/发音错误儿童面部的水银应变仪来监测发/s/音时的下颌位移。每次实验过程的调频磁带录音都生成了同步的音频和下颌位移视频记录，随后进行了分析。结果表明，各种/s/发音错误亚组在发/s/音时表现出不同的下颌位置，并且语音语境对下颌位置的影响也因发音类型而异。
