Problems solved by technology
[0002] At present, when detecting whether there are preset sounds such as infant crying in the audio, it is usually detected by artificial means. For example, when playing the audio, artificially detect whether there is the above-mentioned preset sound in the audio by listening to the audio. However, this artificial detection method not only has low detection efficiency and low accuracy rate, but also requires too many human operations, and the burden of human detection is relatively heavy.

The invention relates to a sound detection method and device. The method includes: extracting the audio features of the audio frame of the audio to be detected; based on the audio features of the audio frame, determining the posterior probability that the audio frame belongs to a preset sound; according to the preset weight of the audio frame and the The audio frame belongs to the posterior probability of the preset sound, and detects whether the preset sound exists in the audio to be detected. Through the technical solution of the invention, the detection efficiency and correct rate of preset sounds in audio can be improved, the purpose of reducing false detection can be achieved, artificial detection of preset sounds can be avoided, and the detection burden of users can be reduced.
Description
technical field [0001] The present invention relates to the technical field of terminals, and in particular, to a sound detection method and device. Background technique [0002] At present, when detecting whether there is a preset sound such as a baby crying in the audio, the detection is usually performed manually. For example, when the audio is played, the audio is manually detected by listening to the audio. However, this manual detection method not only has low detection efficiency and low accuracy, but also requires too many manual operations, and the burden of manual detection is relatively heavy. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide a sound detection method and apparatus. The technical solution is as follows: [0004] According to a first aspect of the embodiments of the present invention, a sound detection method is provided, including: [0005] Extract the audio features of the audio frame of the audio to be detected; ...
