摘要
针对语音和噪音的特点,提出在高噪声条件下,用LPC全极点模型的增强算法,进行系统实现及比较和测试。系统在较高噪声背景下,该方法具有很好的去噪效果。
After analyzing the features of speech and noise, an speech enhancement method in view of LPC autoregressive for command words recognition used . in noise environment is proposed, and an experimental system is realized . The experimental results show w the method is effective in noise environment.
