摘　　要：文章基于MATLAB软件,对一段录制并加入高斯噪声的wav语音信号进行综合分析与处理。处理操作包括语音加密、音量标准化、滤波处理及音段定位。经过处理后,语音信号的访问安全性与信噪比得以提升。基于语音间隙进行音段定位后,便于提取语音片段中的关键信息。Based on MATLAB software,this paper comprehensively analyzes and processes a recorded wav speech signal with Gaussian noise.Processing operations include voice encryption,volume standardization,filtering processing and segment positioning.After processing,the access security and signal-to-noise ratio of voice signals are improved.It is convenient to extract the key information in the speech segment after locating the speech segment based on the speech gap.

关 键 词：语音加密 音量标准化 滤波处理 音段定位
