Abstract
The relative independence of time-unit processing during speech reception was examined. It was found that temporally interpolated noise, even at very high levels, had little effect on sentence recognition using masking-release conditions similar to those of Kwon et al. [(2012). J. Acoust. Soc. Am. 131, 3111-3119]. The current data confirm the earlier conclusions of Kwon et al. involving masking release based on the relative timing of speech and noise. These data also indicate substantial levels of independence in the time domain, which has implications for current theories of speech perception in noise.
摘要
研究了言语接收过程中时间单元处理的相对独立性。结果发现，即使在非常高的水平下，使用与Kwon等人（2012年，《美国声学学会杂志》131卷，3111 - 3119页）类似的掩蔽释放条件时，时间内插噪声对句子识别影响很小。当前数据证实了Kwon等人基于语音和噪声相对时间的掩蔽释放的早期结论。这些数据还表明在时域中存在相当程度的独立性，这对当前的噪声中语音感知理论具有启示意义。
