在不同水平和时间调制率（TMR）的语音调制噪声中测量可懂度。声学分析测量了高于当地信噪比标准（LC）的一瞥。瞥见的比例和速率与可懂度相关，特别是分别与掩蔽水平或TMR操作相关。在不同的分析LC中，每个指标的可懂度相关性最大化。回归分析表明，在-2 dB LC测量的这两个指标需要最好地解释总方差（R-2 = 0.49）为个别句子的可懂度。声学条件与识别语音在复杂的掩蔽最好的解释使用多维的一瞥指标。(C)2018年美国声学学会
Intelligibility was measured in speech-modulated noise varying in level and temporal modulation rate (TMR). Acoustic analysis measured glimpses available above a local signal-to-noise ratio criterion (LC). The proportion and rate of glimpses were correlated with intelligibility, particularly in relation to masker level or TMR manipulations, respectively. Intelligibility correlations for each metric were maximized at different analysis LCs. Regression analysis showed that both metrics measured at -2 dB LC were required to best explain the total variance (R-2 = 0.49) for individual sentence intelligibility. Acoustic conditions associated with recognizing speech in complex maskers are best explained using multidimensional glimpse metrics. (C) 2018 Acoustical Society of America
