摘要

区分喊叫和非喊叫语音在交流中至关重要。我们研究了喊叫如何影响振幅包络(ENV)的时间特性,共 720 个句子,由 18 位瑞士德语使用者以正常和喊叫模式朗读;喊叫的特点是在距口腔 1 米处保持≥80 dB 声压级(dB-SPL)(C-加权)。广义相加模型显示,喊话语音中的 ENV 有明显的时间变化,其特点是上升更陡、峰值延迟和高电平延长。这些发现为识别喊叫声提供了潜在的线索,在缺乏精细结构和动态范围线索时尤其有用,例如对于人工耳蜗使用者。

Shouting affects temporal properties of the speech amplitude envelope.

Distinguishing shouted from non-shouted speech is crucial in communication. We examined how shouting affects temporal properties of the amplitude envelope (ENV) in a total of 720 sentences read by 18 Swiss German speakers in normal and shouted modes; shouting was characterised by maintaining sound pressure levels of ≥80 dB sound pressure level (dB-SPL) (C-weighted) at a 1-meter distance from the mouth. Generalized additive models revealed significant temporal alterations of ENV in shouted speech, marked by steeper ascent, delayed peak, and extended high levels. These findings offer potential cues for identifying shouting, particularly useful when fine-structure and dynamic range cues are absent, for example, in cochlear implant users.
