混响声能对语音清晰度的负面影响是有据可查的。然而，最近，事先暴露于室内声学已被证明可以提高模拟室内环境中许多听众的可懂度。这种房间自适应效果是动态回声抑制的一种可能的扩展，已经被证明是混响房间所特有的，并且需要双耳输入。因为这种效果已经证明，只有使用协调反应测量（CRM）语料库，重要的是要确定是否增加可懂度分数报告先前是由于CRM任务的特定性质。在这里，我们展示了一个可比的房间声学效果，使用修改后的押韵测试（MRT）语料库在多个房间的环境。实验结果与混响环境中的房间适应效应是一种自然现象的观点是一致的。
The negative effect of reverberant sound energy on speech intelligibility is well documented. Recently, however, prior exposure to room acoustics has been shown to increase intelligibility for a number of listeners in simulated room environments. This room adaptation effect, a possible extension of dynamic echo suppression, has been shown to be specific to reverberant rooms and requires binaural input. Because this effect has been demonstrated only using the Coordinated Response Measure (CRM) corpus it is important to determine whether the increase in intelligibility scores reported previously was due to the specific nature of the CRM task. Here we demonstrate a comparable room-acoustic effect using the Modified Rhyme Test (MRT) corpus in multiple room environments. The results are consistent with the idea that the room adaptation effect may be a natural phenomenon of listening in reverberant environments.
