Speech Recognition Technology Based On Microphone Array

摘要

In recent years, with the development of voice technology and the improvement of technology level, speech recognition technology has reached a large-scale commercial level. However, speech recognition technology still has many defects, and the existence of these defects restricts the accuracy of speech recognition. For example, when the multi speaker problem exists, the accuracy of speech recognition will drop dramatically, which will affect the effect of speech recognition. From the perspective of microphone array, this paper attempts to combine the positioning and noise reduction technology of microphone array with speech recognition technology in order to solve this problem. Experimental results show that microphone arrays can locate specific speakers, and design nulls to remove noises beyond the speaker's direction.
