声调协同发音通常会引起F0（Xu，1997; Brunelle，2009）以及语音质量（DiCanio，2012）的变化。在普通话中，语音质量与F0相关，因此当F0高于或低于中音时，语音质量通常会变得更脆弱（Kuang，2017）。然而，很少有研究探讨协同发音如何影响音调的音质。本研究利用音频和电声门图（EGG），探讨了协同发音对普通话声调F0和音质的影响。刺激包括三音节的普通话复合词，其中四个普通话声调中的每一个都被不同的声调所包围，以实现全方位的上下文变化。我们期望高音调的F0（例如，音调1）在两侧是低音时会变得更低（例如，音调3），而当与高音相邻时，低音的F0将变得更高。此外，如果语音质量取决于F0，则在F0中提高的音调3的语音质量应该变得更加模态。结果的讨论将强调如何F0和语音质量的普通话音调可以根据音调的上下文和如何发音（EGG测量）通知声学实现的模式。
Tonal coarticulation often induces changes in F0 (Xu, 1997; Brunelle, 2009) as well as voice quality (DiCanio, 2012). In Mandarin, voice quality covaries with F0, such that when the F0 is higher or lower than the mid-range pitch, the voice quality often becomes creakier (Kuang, 2017). However, fewer studies have examined how coarticulation can affect a tone’s voice quality. Using audio and electroglottography (EGG), this study investigates how F0 and voice quality of Mandarin tones are affected by coarticulation. The stimuli consisted of trisyllabic Mandarin compounds, where each of the four Mandarin tones is flanked by varying tones, for a full range of contextual variation. We expect that the F0 of a high tone (e.g., Tone 1) would become lower when flanked by a low tone (e.g., Tone 3), whereas the F0 of a low tone would become higher when adjacent to a high tone. Moreover, the voice quality of Tone 3 that is raised in F0 should become more modal, if voice quality depends on F0. Discussion of results will emphasize how F0 and voice quality of Mandarin tones can vary according to tonal context and how articulation (as measured by EGG) informs patterns of acoustic realization.
