Intelligent voice-to-text and simultaneous translation system based on microphone array

Abstract

The invention provides an intelligent voice-to-text and simultaneous translation system based on a microphone array. The intelligent voice-to-text and simultaneous translation system can remove or reduce a plurality of competitive interference noises in real time; a target sound source is intelligently recognized, and enhancement processing of a target voice signal is realized; then, the voice-to-text and simultaneous translation functions are further realized; and the equipment is small in size and easy to carry. In the technical scheme of the invention, a pickup system composed of double microphones (microphone arrays) based on core hardware is used for picking up voice signals. A module based on digital signal processing (DSP) intelligently selects target voice in real time and removesor reduces competitive interference noise in real time. The intelligent voice-to-text and simultaneous translation system is used in cooperation with a mobile phone capable of converting voice into characters and translating, target voice signals can be intelligently recognized in real time in a multi-competitive interference noise environment, target voice is enhanced, and finally the functions of converting voice into characters and translating at the same time are achieved.

Description

technical field [0001] The invention relates to the technical field of speech recognition, in particular to an intelligent speech-to-text and simultaneous translation system based on a microphone array. Background technique [0002] In the current international background, we have more and more opportunities to communicate with international friends, but people of different nationalities have different mother tongues, and different languages ​​are a huge obstacle in communication; although translation software and simultaneous translation software have already However, in a noisy environment, due to the existence of competing sound sources, the sound source with low signal-to-noise ratio (SNR) makes the effect of speech-to-text translation and the translation effect of simultaneous translation software not very satisfactory. [0003] There are already some related invention patents and related application software in China. In terms of front-end denoising, Zeng Qingning and...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems existing in the existing simultaneous translation equipment, such as the difficulty in identifying the target sound source among the competing sound sources, and the equipment being too large to carry easily, the present invention provides an intelligent speech-to-text and simultaneous translation system based on a microphone array, It can intelligently identify the target sound source, remove or reduce competitive noise, perform speech-to-text transcription and translation after speech enhancement on the target sound source, and the device is small and easy to carry
