Speech Signal Processing of Industrial Speech Recognition

Abstract The noise in the industrial production environment is more complex than application scenario home or office environment, and most of loudness much larger. Automatic speech recognition(ASR) system will fail when front-end signal processing SNR too poor. At this time ability particularly important. product solution mentioned article involves multiple point. It includes omnidirectional Microphones Array scheme selection, selection Mic monomer, sampling, digitization, reduction echo processing, so as to improve overall recognition rate under noise,therefore, it has become an AR head-mounted computer for intelligent accepted by many business worldwide.
