最近的研究表明，高频（>6 kHz）和扩展高频（EHF; >8 kHz）听力对于噪声中的语音识别是有价值的。一些研究还表明，EHF纯音阈值预测语音噪声性能。这些发现与广泛接受的“语音带宽”相矛盾，该带宽在历史上被限制在8 kHz以下。这项不断增长的工作是对Pat Stelmachowicz工作的致敬，他的研究有助于揭示先前语音带宽工作的局限性，特别是对女性说话者和儿童听众。在这里，我们提供了一个历史回顾，展示了Stelmachowicz和她的同事的工作如何为后续研究铺平了道路，以测量扩展带宽和EHF听力的影响。我们还提出了在我们的实验室，其结果表明，16 kHz的纯音阈值的语音噪声性能的一致预测，无论是否EHF线索存在于语音信号中收集的以前的数据的重新分析。基于Stelmachowicz和她的同事以及后来的研究，我们认为，现在是时候让儿童和成人的言语感知的言语带宽有限的概念退休了。
Recent work has demonstrated that high-frequency (>6 kHz) and extended high-frequency (EHF; >8 kHz) hearing is valuable for speech-in-noise recognition. Several studies also indicate that EHF pure-tone thresholds predict speech-in-noise performance. These findings contradict the broadly accepted “speech bandwidth” that has historically been limited to below 8 kHz. This growing body of work is a tribute to the work of Pat Stelmachowicz, whose research was instrumental in revealing the limitations of the prior speech bandwidth work, particularly for female talkers and child listeners. Here, we provide a historical review that demonstrates how the work of Stelmachowicz and her colleagues paved the way for subsequent research to measure effects of extended bandwidths and EHF hearing. We also present a reanalysis of previous data collected in our lab, the results of which suggest that 16-kHz pure-tone thresholds are consistent predictors of speech-in-noise performance, regardless of whether EHF cues are present in the speech signal. Based on the work of Stelmachowicz, her colleagues, and those who have come afterward, we argue that it is time to retire the notion of a limited speech bandwidth for speech perception for both children and adults.
