研究了真实的房间混响（T=0.75秒）对年轻听力正常受试者语音识别的影响。初始与最终和安静与混响的结果显着不同。位置信息的影响最大，其次是摩擦。停止和鼻信息其次受到影响。发声是相当强大的;和持续时间，咝咝声，和液体信息几乎不受影响。出现了几种有趣的混淆模式。除了相对较高的摩擦敏感性外，混响对语音识别的影响似乎与掩蔽和低通滤波的报告有些相似。混响似乎导致语音信号的时间拖尾，从而充当语音形状的掩蔽噪声。此外，短持续时间的事件出现延长，似乎与停止被报告为摩擦音;和相对较长的时间传播的基本共振峰和较低的共振峰似乎与停止被报告。
The effects of real room reverberation (T=0.75 sec) on speech sound recognition was investigated for young, normal‐hearing subjects. Initial versus final and quiet versus reverberant results were significantly different. Place information was most affected, followed by frication. Stop and nasal information were next affected. Voicing was quite robust; and duration, sibilance, and liquid information were virtually unaffected. Several interesting confusion patterns emerged. Except for the relatively high susceptibility of frication, the effects of reverberation on speech recognition seem somewhat similar to that reported for masking and low‐pass filtering. Reverberation appears to result in temporal smearing of the speech signal, so as to act as a speech‐shaped masking noise. Also, short‐duration events appear lengthened, and seem to be associated with stops being reported as fricatives; and relatively long temporal spreading of the fundamental and lower formants appears to be associated with stops being re...
