spectral subtraction method meaning in English

光谱差减法

This paper studies the speech enhancement technology , and proposes an improved spectral subtraction method based on the auditory characteristics and the speech spectrum characteristics
本文以语音增强为研究课题,提出基于人耳听觉特性和语音语谱特性的语音增强方法。
In this paper , a new spectral subtraction method is presented , which breaks the assumption that the noise is gaussian distribution with mean 0 in the original spectral subtraction method
本文针对谱减法中关于噪声是零均值的高斯分布的假设,提出了一种可以打破这一假设的改进谱减算法。
Then this spectral subtraction method is applied to noise speech recognition system as the front - end processing . noise speech signal are processed to improve its snr before recognition . so the recognition rate can be improved in noise environments
并将改进谱减算法作为噪声下语音识别系统的前端处理过程,即通过对含噪的语音进行语音增强以提高信号的信噪比,从而提高语音识别系统的抗噪声性能。
