| Abstract: | 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. |
