AI总结:

本研究比较了CamHLS和WHIS两种听力损失模拟器的音质,发现采用DTVF算法的WHIS在非线性处理下仍能显著减少语音失真,为信号合成应用提供了有效方案。

摘要:

听力损失(HL)模拟器能让正常听力(NH)听者体验HL,已用于语音清晰度实验,但因可感知的失真未用于音质实验。若其产生的失真较小,可能有助于NH听者评估如助听器等设备的音质。我们开展了感知音质实验,比较了Cambridge版HL模拟器(CamHLS)和Wakayama版HL模拟器(WHIS),后者包含滤波器组分析合成(FBAS)和直接时变滤波器(DTVF)两种算法。实验结果表明,即使非线性处理在工作,采用DTVF的WHIS在语音中产生的可感知失真也少于CamHLS和采用FBAS的WHIS。这一优势主要归功于DTVF算法的使用,该算法可应用于涉及滤波器组分析的各种信号合成应用。

英文摘要:

Hearing loss (HL) simulators, which allow normal hearing (NH) listeners to experience HL, have been used in speech intelligibility experiments, but not in sound quality experiments due to perceptible distortion. If they produced less distortion, they might be useful for NH listeners to evaluate the sound quality of, for example, hearing aids. We conducted perceptual sound quality experiments to compare the Cambridge version of HL simulator (CamHLS) and the Wakayama version of the HL simulator (WHIS), which has the two algorithms of filterbank analysis synthesis (FBAS) and direct time-varying filter (DTVF). The experimental results showed that WHIS with DTVF produces less perceptible distortion in speech sounds than CamHLS and WHIS with FBAS, even when the nonlinear process is working. This advantage is mainly due to the use of the DTVF algorithm, which could be applied to various signal synthesis applications with filterbank analysis.
