Abstract

The invention discloses a sensitive content identification method, device and terminal based on voice analysis and a medium, wherein the terminal acquires an audio segment to be detected and a currentvoice scene and acquires a voice characteristic vector of each voice frame in the audio segment to be detected, according to a pre-established feedforward sequence memory network model, semantic textcorresponding to the voice feature vector is obtained by using the voice characteristic vector as an input, and a sensitive information base corresponding to the current voice scene is determined, different voice scenes correspond to different sensitive information bases, the accuracy of judging sensitive contents is improved, a sensitivity index of the semantic text is determined according to abidirectional neural network model established in advance and the determined sensitive information bases, and the semantic text is compared with the semantics of the sensitive information bases to further improve the accuracy, and the audio segment to be detected is marked as sensitive content when the sensitivity index is larger than a preset sensitivity threshold.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a sensitive content identification method, device, terminal and medium based on speech analysis. Background technique [0002] Artificial intelligence is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence. Artificial intelligence is a branch of computer science that attempts to understand the essence of intelligence and produce a new intelligent machine that responds in a manner similar to human intelligence. Research in this field includes robotics, speech recognition, image recognition, natural Language processing and expert systems, etc., and speech recognition technology is particularly important in artificial intelligence. [0003] At present, the speech recognition technology of sensitive words is mainly based on the established corpus o...
