几项研究表明，语音中的扩展高频（EHF; >8 kHz）不仅是可听的，而且对语音识别也有一定的实用性，包括当掩蔽者背对听者时的语音识别。然而，EHF频谱与时间信息对语音识别的贡献是未知的。在这里，我们表明，访问EHF的时间信息改善语音识别语音相对于语音带宽限制在8 kHz，但额外的访问EHF频谱细节提供了一个额外的小，但显着的好处。结果表明，EHF频谱结构和时间包络有助于观察到的EHF的好处。语音识别性能对掩蔽头方向非常敏感，仅旋转15°就提供了非常显著的益处。探索性分析表明，纯音阈值在高频语音识别性能比低频纯音阈值更好的预测。
Several studies have demonstrated that extended high frequencies (EHFs; >8 kHz) in speech are not only audible but also have some utility for speech recognition, including for speech-in-speech recognition when maskers are facing away from the listener. However, the contribution of EHF spectral versus temporal information to speech recognition is unknown. Here, we show that access to EHF temporal information improved speech-in-speech recognition relative to speech bandlimited at 8 kHz but that additional access to EHF spectral detail provided an additional small but significant benefit. Results suggest that both EHF spectral structure and the temporal envelope contribute to the observed EHF benefit. Speech recognition performance was quite sensitive to masker head orientation, with a rotation of only 15° providing a highly significant benefit. An exploratory analysis indicated that pure-tone thresholds at EHFs are better predictors of speech recognition performance than low-frequency pure-tone thresholds.
