Design of Speech Recognition System Based on Linear Microphone Array

In order to achieve the accuracy of voice recognition in the process of voice interaction in complex scenes, and to achieve functions such as noise suppression, reverberation removal, sound source direction finding, and sound source tracking, a linear microphone array has been studied to achieve speech recognition. Firstly, for complex speech recognition scenarios, a linear microphone array with 6 elements is used to perform space-time processing on the collected sound signals in different spatial directions to achieve noise suppression, reverberation removal, vocal interference suppression, sound source direction finding, Sound source tracking. Then improve the speech signal processing quality to improve the speech recognition rate in the real environment. The design of Speech Recognition System Based on Linear Microphone Array,The embedded design scheme has realized the directional pickup and processing of the sound signal of the 6-line microphone array. Experiments have proved that the system is stable and reliable, has a large amount of collected data, has good synchronization, has a high signal-to-noise ratio, and has a friendly human-machine interface. It can be widely used in vehicles, shipborne, airborne and other devices with voice recognition.
