| 摘 要： | 语音增强技术一直是语音信号处理中的重要课题之一,语音增强的目的是从有噪声的信号中尽可能完好地恢复原始声音。目前常用的增强算法很多,本文对传统的基于短时谱估计的增强算法和近年来发展起来的基于小波变换的增强算法进行仿真实验比较研究。

| Abstract: | The speech intensified technique is an important lesson in the speech signal processing. The purpose is to get back speech signal from the signal containing noise, At present, there are many speech intensified techniical arithmetics. This paper contrasts two kinds of speech intensified techniques which are based on short time spectrum and based on wavelet transform. |
