Abstract

The invention discloses a sensitive speaker monitoring and recording control method and system based on deep learning. The method comprises the following steps of: acquiring recorded audio information, extracting an audio characteristic value of the audio information by adopting a triple loss method based on a time pool and cosine similarity, inputting the audio characteristic value into a pre-trained speaker model of the sensitive speaker, and outputting a matching value of the voice matching degree with the sensitive speaker, comparing the matching value with a preset matching threshold value, if the matching value is smaller than the matching threshold value, determining that the speaker is not a sensitive speaker, and not recording the audio information, otherwise, storing the audio information, and meanwhile, updating the speaker model of the sensitive speaker. The method has the advantages that the accuracy of monitoring the sensitive speaker is improved; and the problem that existing recording does not distinguish speakers or cannot accurately judge a target speaker is solved.

Description

technical field [0001] The invention relates to a sensitive speaker monitoring and recording control method and system based on deep learning, belonging to the technical field of speech signal processing. Background technique [0002] Voice monitoring is one of the main means of stealing intelligence in espionage. In contemporary countries, monitoring has been regarded as an important technical means to steal other countries' military, political, economic, scientific and industrial intelligence, among which the monitoring of specific sensitive speakers is particularly important. Now there are all kinds of monitoring devices, such as wireless pinhole camera monitoring devices, "light" monitoring devices, "desk lamp" monitoring devices, laser monitoring devices, etc. These monitoring devices can hide themselves very well without being discovered. However, these monitoring devices can only save all the monitored content without reservation, and these content is not necessaril...
