Speech intelligibility has been shown to improve with prior exposure to a reverberant room environment [Brandewie and Zahorik (2010). J. Acoust. Soc. Am. 128, 291-299] with a spatially separated noise masker. Here, this speech enhancement effect was examined in multiple room environments using carrier phrases of varying lengths in order to control the amount of exposure. Speech intelligibility enhancement of between 5% and 18% was observed with as little as 850 ms of exposure, although the effect's time course varied considerably with reverberation and signal-to-noise ratio. In agreement with previous work, greater speech enhancement was found for reverberant environments compared to anechoic space.
先前的研究表明，在存在空间分离噪声掩蔽的混响环境中，人们对语音的可懂度会提高[Brandewie 和 Zahorik（2010）。J. Acoust. Soc. Am. 128, 291-299]。在这里，使用不同长度的载波短语来控制暴露量，在多个房间环境中检查了这种语音增强效果。研究人员发现，即使暴露时间只有 850 毫秒，也能将语音可懂度提高 5%到 18%，尽管该效果的时间进程随混响和信噪比而有很大差异。与之前的研究一致，与消声空间相比，混响环境中的语音增强效果更大。
