Abstract

Classic demonstrations of the phonemic restoration effect show increased intelligibility of interrupted speech when the interruptions are caused by a plausible masking sound rather than by silent periods. Previous studies of this effect have been conducted exclusively under anechoic or nearly anechoic listening conditions. This study demonstrates that the effect is reversed when sounds are presented in a realistically simulated reverberant room (broadband T(60) = 1.1 s): intelligibility is greater for silent interruptions than for interruptions by unmodulated noise. Additional results suggest that the reversal is primarily due to filling silent intervals with reverberant energy from the speech signal.

摘要

经典的音位恢复效应演示表明，当中断是由合理的掩蔽声而不是静音期引起时，中断的语音可懂度会提高。之前对该效应的研究仅在消声或近乎消声的聆听条件下进行。本研究表明，当声音在逼真的混响室中呈现时（宽带 T（60）= 1.1 秒），该效应会发生反转：静音中断的可懂度大于未调制噪声中断的可懂度。其他结果表明，反转主要是由于用语音信号的混响声填充静音间隔。
