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 comprises the steps: obtaining far-field audio data through a sound collection device; obtaining the far-field audio data by a recording sound card and saving the far-field audio data to a processor; converting the far-field audio data into a far-field text annotation by a processor according to a far-field model database; obtaining near-field audio data from a near-field model database according to the far-field text annotation, wherein the near-field audio data is used for amplified playing. According to the invention, the sound can be amplified without affecting the sound quality of the sound, noises can be removed, interference caused by echoes is effectively avoided, and the sound in different distance scenes is selectively played, a more human-friendly effect is realized, and the sound is 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 ...
