摘要

频率重要度函数量化了频谱频率对感知的贡献。频率重要性在安静和稳态噪声的语音识别中得到了很好的描述。然而,目前还不清楚频率重要性估计值是否适用于更复杂的条件,如在多人掩蔽下或当目标和掩蔽者在空间上分离时的听力。在这里,频率重要性是通过量化听觉滤波器库输出的局部目标与掩蔽者比率与句子关键词识别准确率之间的关联来估算的。与用于测量频率重要性的传统方法不同,该技术在估算频率重要性时无需改变目标或掩蔽者的声学特性。在噪声和双语掩蔽器中的句子,以及在与目标同处或空间上分离的双语掩蔽器中的句子,频率重要性都进行了比较。结果表明,频率的重要性取决于掩蔽器的类型和空间配置。相对于噪声掩蔽器,在双语掩蔽器存在的情况下,频率高于 5 kHz 的频率重要性较低,频率在 600 到 1900 Hz 之间的频率重要性较高。空间隔离增加了 600 Hz 至 5 kHz 频率的重要性。因此,频率重要性函数在不同的聆听条件下会有所不同。

Frequency importance for sentence recognition in co-located noise, co-located speech, and spatially separated speech.

Frequency importance functions quantify the contribution of spectral frequencies to perception. Frequency importance has been well-characterized for speech recognition in quiet and steady-state noise. However, it is currently unknown whether frequency importance estimates generalize to more complex conditions such as listening in a multi-talker masker or when targets and maskers are spatially separated. Here, frequency importance was estimated by quantifying associations between local target-to-masker ratios at the output of an auditory filterbank and keyword recognition accuracy for sentences. Unlike traditional methods used to measure frequency importance, this technique estimates frequency importance without modifying the acoustic properties of the target or masker. Frequency importance was compared across sentences in noise and a two-talker masker, as well as sentences in a two-talker masker that was either co-located with or spatially separated from the target. Results indicate that frequency importance depends on masker type and spatial configuration. Frequencies above 5 kHz had lower importance and frequencies between 600 and 1900 Hz had higher importance in the presence of a two-talker masker relative to a noise masker. Spatial separation increased the importance of frequencies between 600 Hz and 5 kHz. Thus, frequency importance functions vary across listening conditions.
