Although repetition is the most commonly used conversational repair strategy, little is known about its relative effectiveness among listeners spanning the adult age range. The purpose of this study was to identify differences in how younger, middle-aged, and older adults were able to use immediate repetition to improve speech recognition in the presence of different kinds of maskers. Results suggest that all groups received approximately the same amount of benefit from repetition. Repetition benefit was largest when the masker was fluctuating noise and smallest when it was competing speech.
尽管重复是最常用的会话修复策略,但对于其在不同年龄段听众中的相对有效性却知之甚少。本研究的目的是确定年轻人、中年人及老年人在不同类型掩蔽音存在的情况下,如何利用即时重复来提高语音识别能力的差异。结果表明,所有组从重复中获得的益处大致相同。当掩蔽音为波动噪声时,重复带来的益处最大;当掩蔽音为竞争语音时,重复带来的益处最小。
