Problems solved by technology
[0004] However, these technologies can only distinguish noises in different directions, but cannot effectively suppress noises in the same direction, and due to the existence of side lobes, some noises from other directions will leak into the target direction, resulting in the detection of non-targets. The noise suppression ability in the direction is limited. When the signal and noise are in the same direction, it cannot be suppressed, and the distance cannot be effectively distinguished. ) applies
[0005] For the above problems, the industry has not yet provided a better solution

The invention discloses an audio processing method and device. The method comprises the following steps: determining target azimuth information corresponding to a speaker sound source in candidate audio data; judging whether the target azimuth information is in a preset azimuth range or not; if the target azimuth information is out of the preset azimuth range, filtering out the candidate audio data; and if the target azimuth information is within the preset azimuth range, determining target audio data used for being input to a voice recognition module according to the candidate audio data. Therefore, noise at a distance in the same direction can be filtered, and the method is suitable for being applied to a near-field voice scene.
Description
technical field [0001] The invention belongs to the technical field of voice equipment, and in particular relates to an audio processing method and device. Background technique [0002] With the development of speech technology, various speech recognition technologies have been proposed by many experts and scholars, thus improving the reliability of speech recognition results. However, the quality of the collected audio will also affect the reliability of the speech recognition result. For example, if the audio has a large noise component, it will seriously affect the speech recognition result. [0003] In order to improve the quality of collected audio data, some experts and scholars in related technologies have envisioned and designed related solutions, such as using beamforming technology to divide the space into multiple beams, and suppressing signals in other directions by retaining signals in specific directions. Signal. [0004] However, these technologies can only ...
