在本文中，我们提出了一种新的技术来设计调制滤波器，以减少混响环境下语音清晰度的退化。利用逆调制传递函数，我们设计了每个语音频带的数据导出调制滤波器。这些过滤器预处理麦克风和扬声器之间的语音信号，扬声器将语音辐射到表演大厅。我们利用调制滤波器对一名听力受损的受试者和两名听力正常的受试者进行了感知实验。测试结果表明，该方法提高了混响语音的可理解性。
In this paper, we propose a new technique to design modulation filters to reduce degradation of speech intelligibility in reverberant environments. Using the inverse modulation transfer function, we design data-derived modulation filters for each speech frequency band. These filters preprocess speech signals between a microphone and a loudspeaker that radiates speech into a performance hall. Using our modulation filters, we conducted perceptual experiments with one hearingimpaired subject and two subjects with normal hearing. Test results indicate that our proposed method improves the intelligibility of reverberant speech.
