摘要 本研究调查了语音时间模式对外国口音话语清晰度降低的影响。使用LPC重新合成和动态时间扭曲对中文母语者说出的短英语短语进行仪器修改，以便将声学片段的持续时间与英语母语者说出的相同短语的标记对齐，同时保留中文使用者的频谱和源特征。同样，母语人士的作品也会被扭曲，以匹配非母语人士的持续时间模式。这些刺激的清晰度是根据以英语为母语的听众在强制选择识别测试中的表现来测量的，该测试有四种选择：正确的短语加上通过听中文作品建议的三个语音相似的干扰短语。未经修饰的中文重音短语的可理解性较差（正确率为 39%），但经过时间校正后显着改善（至 58%）。本土作品的表现很高（94%），但根据中文使用者的时间安排，在时间失真后显着下降（至 83%）。这些结果表明，如果对外语说话者的语音时间特性进行显式训练，那么外语说话者的清晰度可能会得到提高。
Abstract This study investigates the contribution of the temporal patterning of speech to the reduced intelligibility of foreign-accented utterances. Short English phrases spoken by a native Chinese speaker were instrumentally modified, using LPC resynthesis and dynamic time warping, so as to align the duration of acoustic segments with tokens of the same phrases spoken by a native English speaker, while retaining the spectral and source characteristics of the Chinese speaker. Similarly, the native speaker’s productions were distorted to match the durational patterns of the non-native speaker. Intelligibility of these stimuli was measured, based on native English listeners’ performance in a forced-choice identification test with four alternatives: the correct phrase plus three phonetically similar distractor phrases suggested by listening to the Chinese productions. Intelligibility of the unmodified Chinese-accented phrases was poor (39% correct), but improved significantly (to 58%) after temporal correction. Performance on the native productions was high (94%), but declined significantly (to 83%) after temporal distortion according to the Chinese speaker’s timing. These results suggest that intelligibility of foreign-language speakers may be enhanced if explicit training is provided on temporal properties of their speech.
