在竞争性语音中，目标语音的识别可能会受到干扰声的数量和特性的限制，这些干扰声会产生能量掩蔽、包络掩蔽和/或信息掩蔽。在这项研究中，使用一个、两个或四个干扰声测量了言语识别阈（SRT）。目标语音和干扰声的性别相同或不同，并且使用正向时间或反向时间的干扰声测量了SRT。对于正向时间的干扰声，目标语音和干扰声的性别差异对SRT有显著影响，但对于反向时间的干扰声则没有。当说话者多于两人时，使用反向时间的干扰声时的多干扰声惩罚比使用正向时间的干扰声时大得多。
In competing speech, recognition of target speech may be limited by the number and characteristics of maskers, which produce energetic, envelope, and/or informational masking. In this study, speech recognition thresholds (SRTs) were measured with one, two, or four maskers. The target and masker sex was the same or different, and SRTs were measured with time-forward or time-reversed maskers. SRTs were significantly affected by target-masker sex differences with time-forward maskers, but not with time-reversed maskers. The multi-masker penalty was much greater with time-reversed maskers than with time-forward maskers when there were more than two talkers.
