摘　　要：介绍了一种职业噪声环境下的语音增强技术。根据职业噪声的特点,采用运算简单、实时性好、改进的减谱法,对职业噪声环境下的语音信号进行处理和提取,达到增强语音的目的。采用先进的32位ARM微处理器S3C2410,对采集的语音信号进行处理,然后回放,达到既保护人体免受噪声的危害,又不影响语言交流的目的。A kind of speech enhancement technology in factory, noise enviomment was introduced. According to the characteristics of factory noise, enforced spectral subtration arithmetic, the factory noise speech signal was processed and the speech was derived from it. The system introduced ARM microprocessor $3C2410 as the controller. The speech is replayed under the control of S3C2410,this ensured the speech communication quality and avoided the affect of factory noise to the people.
