目的比较时间压缩对男女说话者可理解性的影响。我们假设时间压缩对女性说话者有更大的影响。方法对4名说话者（2名男性）的句子材料进行时间压缩，并在12人牙牙学语背景下对听力正常的年轻成年听者播放原语速和时间压缩语音材料。每个通话者/处理条件被8个监听者听到（totalN= 64）。采用广义线性混合效应模型研究加工条件和说话者性别对关键词可理解性的影响及其交互作用。额外的事后分析检查了处理条件的影响是否与说话的元音空间和词频有关。结果对于原语速的句子，女性和男性说话者的理解程度基本相同。时间压缩降低了所有说话者的可理解性，但对女性说话者的影响明显更大。补充分析表明，时间压缩的影响取决于说话元音空间和词频，随着词频和词频的增加，有害影响显著降低。元音间隔较大的说话者对词频的影响也更大。虽然小说话者的样本限制了关于说话者性别影响的结论，但二次分析表明，元音空间较大的说话者的可理解性不太容易受到时间压缩的负面影响，尤其是对高频词。
PurposeThis preliminary investigation compared effects of time compression on intelligibility for male versus female talkers. We hypothesized that time compression would have a greater effect for female talkers.MethodSentence materials from four talkers (two males) were time compressed, and original-speed and time-compressed speech materials were presented in a background of 12-talker babble to young adult listeners with normal hearing. Each talker/processing condition was heard by eight listeners (totalN= 64). Generalized linear mixed-effects models were used to determine the effects of and interaction between processing condition and talker sex on keyword intelligibility. Additional post hoc analyses examined whether processing condition effects were related to talker vowel space and word frequency.ResultsFor original-speed sentences, female and male talkers were essentially equally intelligible. Time compression reduced intelligibility for all talkers, but the effect was significantly greater for the female talkers. Supplementary analyses revealed that the effect of time compression depended on both talker vowel space and word frequency: The detrimental effect decreased significantly as word frequency and vowel space increased. Word frequency effects were also greater overall for talkers with larger vowel spaces.ConclusionsWhile the small talker sample limits conclusions about the effects of talker sex, the secondary analyses suggest that intelligibility of talkers with larger vowel spaces is less susceptible to the negative effect of time compression, especially for high-frequency words.
