Problems solved by technology

However, this way of sound amplification will amplify the surrounding noise together, forming interference, making it difficult for people to hear clearly, and the echo will also enter the microphone of the loudspeaker again, and will be released again after sound amplification. Heavy voice greatly affects the quality and efficiency of the meeting

Abstract

The invention discloses a far-field audio amplification method based on cloud data. The method includes: acquiring far-field audio data through a sound collection device; acquiring and saving the far-field audio data by a recording sound card, and then transmitting the far-field audio data to a processor; The processor converts the far-field audio data into far-field text annotation according to the far-field model database; obtains near-field audio data from the near-field model database according to the far-field text annotation, and the near-field audio data is used for Amplified playback. The invention can amplify the sound without affecting the sound quality of the sound, can remove the noise, effectively avoid the interference caused by the echo, and selectively play the sound in different distance scenes, which is more humanized and makes the sound clearer.

Description

technical field [0001] The invention belongs to the technical field of speech recognition, and in particular relates to a far-field audio sound amplification method and system based on cloud data. Background technique [0002] Voice amplification technology is very common in daily life. For example, in a meeting, when the conference room is relatively large, in order to allow everyone to hear, devices such as loudspeakers will be used. [0003] Existing loudspeaker equipment converts all received sounds into electric currents, amplifies the electric currents, and releases them in the form of sounds to achieve the purpose of sound amplification. However, this way of sound amplification will amplify the surrounding noise together, forming interference, making it difficult for people to hear clearly, and the echo will also enter the microphone of the loudspeaker again, and will be released again after sound amplification. Heavy voice greatly affects the quality and efficiency ...
