The embodiment of the invention discloses a monitoring processing method and system of audio data. The monitoring process method of the audio data comprises the steps of obtaining multiple audio sample files; preprocessing the audio sample files, and obtaining annotation information of the audio sample files; obtaining multiple Mel frequency cepstrum coefficient (MFCC) characteristic matrices according to the preprocessed audio sample files; adopting a tensorflow framework for training according to the MFCC characteristic matrices and scene information to obtain an audio scene recognition prediction model; obtaining monitored audio data, and utilizing the audio scene recognition prediction model for conducting analytical prediction on the monitored audio data to obtain scene information ofthe audio data. According to the monitoring processing method and system, the mode of converting audios into texts is not needed, instead, monitored audios can be recognized to judge a scene (such asa pornographic / common scene / music scene) where a speaker is located, a scene prediction is made accordingly, and then an early warning about abnormal behaviors under a monitored environment is given.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of audio processing, and in particular to a method and system for monitoring and processing audio data. Background technique [0002] The existing audio monitoring technology mainly realizes audio monitoring by recording audio and storing it, then converting the audio into text, and then recognizing the text. This method does not identify the audio itself, let alone achieve real-time early warning. Contents of the invention [0003] To this end, the embodiments of the present invention provide a method and system for monitoring and processing audio data, so as to solve the problems in the prior art that audio itself cannot be identified and audio monitoring cannot be performed in real time. [0004] In order to achieve the above purpose, embodiments of the present invention provide the following technical solutions: [0005] The embodiment of the first aspect of the present inventio...
