Earlier studies report systematic differences across speakers in the occurrence of utterance-final irregular phonation; the work reported here investigated whether human listeners remember this speaker-specific information and can access it when necessary (a prerequisite for using this cue in speaker recognition). Listeners personally familiar with the voices of the speakers were presented with pairs of speech samples: one with the original and the other with transformed final phonation type. Asked to select the member of the pair that was closer to the talker's voice, most listeners tended to choose the unmanipulated token (even though they judged them to sound essentially equally natural). This suggests that utterance-final pitch period irregularity is part of the mental representation of individual speaker voices, although this may depend on the individual speaker and listener to some extent.
早期研究报告了不同说话者在话语结尾不规则发声的出现上存在系统性差异;本文所报告的研究调查了人类听众是否能记住这种特定于说话者的信息,并在必要时获取它(这是在说话者识别中使用此线索的先决条件)。让熟悉说话者声音的听众听成对的语音样本:一个是原始的,另一个是结尾发声类型经过改变的。当被要求选择更接近说话者声音的那一对样本时,大多数听众倾向于选择未被处理的样本(尽管他们认为两者听起来基本同样自然)。这表明话语结尾的音长周期不规则性是个体说话者声音心理表征的一部分,尽管这在一定程度上可能取决于个体说话者和听众。
