1) perceptual weighting
感觉加权
1.
Speech enhancement method based on multi-band spectral subtraction plus perceptual weighting;
多带谱相减结合感觉加权的语音增强方法研究
2.
A speech enhancement method based on multi-band spectral subtraction plus the perceptual weighting algorithm is put forward.
谱减法通过处理后的语音中会留下所谓的"音乐噪声",针对这个问题,提出了一种多带谱相减与感觉加权相结合的语音增强方法。
2) Perceptual Weighting Filter
感觉加权滤波器
1.
For solving this problem and improving the wideband synthesis speech quality more efficiently,a novel perceptual weighting filter is proposed in this paper.
由于宽带语音编码低频到高频的谱动态范围加宽,频谱倾斜现象更加显著,为了解决宽带语音编码频谱倾斜问题,进一步提高宽带语音合成语音质量,该文提出了一种新的感觉加权滤波器,并将其应用到了自适应多速率宽带语音编码AMR-WB算法中,仿真实验结果表明,新设计的感觉加权滤波器不仅有效解决了宽带语音频谱倾斜问题,且使AMR-WB 9种语音编码模式的平均w-PESQ值得到了提高。
3) conception power of mean square error
感觉加权均方误差
4) Perceptual Linear Predictive(PLP)
感觉加权线性预测
1.
Aiming at the acoustic features of some easily confused mandarin speech recognition, this paper directs towards revising the Perceptual Linear Predictive(PLP) acoustic feature of these consonants by applying wavelet packet decomposition theory, in which a new feature extraction algorithm is proposed.
针对汉语普通话语音识别中易混淆音素的声学特征,把小波包分解理论应用在感觉加权线性预测(PLP)特征中,提出一种新的特征参数提取算法,可以更精确地描述易混淆音素的频谱特征。
5) sensory processing
感觉加工
6) Perceptualw eighting
知觉加权
