In order to enhance a quality of speech corrupted by additive background noise, this research aims that perceptually good output speech removed the noise is achieved by the spectral subtraction approach based on a perceptual weighting function concerned with an auditory masking effect.I think that this research was approximately done along to the beginning plan. In the first year the result-1 was obtained by introducing the perceptual weighting function to the noise suppression system and by evaluating its performance. In the next year the results-2 were obtained by controlling the scaling factors adaptively. In addition, the results of this research were presented at the international conference and at the domestic meeting or society and contributed to the journal of IEICE.RESEARCH RESULTS1. Introducing of algorithm using perceptual frequency weighting to reduce the noise spectrumIt was proposed that the approach reduces the background noise by using the perceptual scaling function obtained from the spectral envelope of the input speech.2. Improvement of algorithm obtained from the first year's research(1) It was proposed that the approach improves the accuracy of the spectral envelope estimation by the fact that linear prediction coefficients are calculated from the signal which applies one time simple spectral subtraction method. The quality of the output signal reduced the noise was improved.(2) It was proposed that the approach controls adaptively the values of weighting factors by changing the weighting factors from the fixed value (in first year) to the variable value (in the next year). As a result of this approach the accurate estimation of noise spectrum was obtained.

为了提高因添加背景噪声破坏的语音质量，这项研究的目的是，基于与听觉掩盖效果有关的感知加权功能，通过频谱减法方法来消除噪声是通过频谱减法方法实现的。在第一年，结果1是通过将感知加权函数引入噪声抑制系统并评估其性能来获得的。明年，结果2是通过自适应控制缩放因子来获得的。此外，这项研究的结果是在国际会议和国内会议或社会上提出的，并为IEICE杂志做出了贡献。研究结果1。提出了使用感知频率加权引入算法来减少噪声谱的算法，该方法通过使用从输入语音的光谱信封获得的感知缩放函数来降低背景噪声。2。从第一年的研究中获得的算法的改进（1）提出，该方法通过以下事实来提高光谱包络估计的准确性，即线性预测系数是根据应用一次简单光谱减法方法的信号计算得出的。输出信号的质量降低了噪声。（2）提出该方法通过将加权因子从固定值（第一年）更改为可变值（明年）来适应加权因子的值。由于这种方法，获得了噪声光谱的准确估计。
