本研究探讨了短暂接触非母语语言的感知益处。以英语为母语的听众听非英语为母语的人说的英语句子。通过测量每个句子后对视觉探测词的反应时间来跟踪感知处理速度。用西班牙语和汉语口音进行的三个实验表明，口音语音的处理速度最初比母语语音慢，但这种缺陷在一分钟内就会消失。控制条件排除了基于任务练习和处理困难言语的一般策略的适应效应的解释。进一步的结果表明，适应可以在短短两到四个句子长度的话语中发生。研究结果强调了人类语音处理的灵活性，并要求口语单词识别模型能够迅速适应与母语语音模式的显著声学-语音偏差。(C) 2004美国声学学会。
This study explored the perceptual benefits of brief exposure to non-native speech. Native English listeners were exposed to English sentences produced by non-native speakers. Perceptual processing speed was tracked by measuring reaction times to visual probe words following each sentence. Three experiments using Spanish- and Chinese-accented speech indicate that processing speed is initially slower for accented speech than for native speech but that this deficit diminishes within one minute of exposure. Control conditions rule out explanations for the adaptation effect based on practice with the task and general strategies for dealing with difficult speech. Further results suggest that adaptation can occur within as few as two to four sentence-length utterances. The findings emphasize the flexibility of human speech processing and require models of spoken word recognition that can rapidly accommodate significant acoustic-phonetic deviations from native language speech patterns.
