Abstract

The invention provides a method of reducing interior noise and improving a voice recognition rate. The method of reducing the interior noise and improving the voice recognition rate includes the steps: S1, processing recorded voice, conducting analog to digital (A/D) conversion, obtaining and storing a voice digital quantity; S2, extracting the voice digital quantity and comparing the voice digital quantity with a preset voice sample, and obtaining a comparison result; S3, executing the comparison result and feeding the comparison result back to a user. The invention further discloses a device and equipment of reducing the interior noise and improving the voice recognition rate. The device of reducing the interior noise and improving the voice recognition rate and equipment of reducing the interior noise and improving the voice recognition rate solve the problem that in an environment with noisy vehicles, the voice recognition rate of a vehicle navigation is low, guarantee the precise voice recognition rate in a complex speech environment and improve reliability and stability of the voice recognition system in a vehicle navigation sound, and meanwhile can be used in voice control systems of other electronic industries.

Description

technical field [0001] The invention relates to the field of speech recognition of vehicle navigation audio, in particular to a method, device and equipment for reducing noise in a car and improving speech recognition rate. Background technique [0002] Speech recognition technology is one of the important technological development technologies in the field of information technology in the future. It is an interdisciplinary subject and is gradually becoming the key technology of human-computer interaction in information technology. Making a machine understand what you say has been a long-held dream. Speech recognition technology is to allow machines to convert voice signals into corresponding commands and instructions through the process of recognition and understanding to achieve every job or complete something. In the past two decades, speech recognition technology has made significant progress. The combination of speech recognition technology and speech synthesis techno...
