Problems solved by technology
[0002] At present, the voiceprint recognition technology usually first obtains the voice information of the suspect, extracts the voiceprint information in the voice information, compares the voiceprint information with the data in the public security voiceprint database, and obtains the comparison result; among them, the public security voiceprint The library includes the national voiceprint library and the provincial voiceprint library. The national voiceprint library and the provincial voiceprint library will be updated and stored in real time, which will cause the audio information in the national voiceprint library and the provincial voiceprint library to be different. , it is easy to miss some audio information, and even affect the detection of the case, which will lead to data redundancy in the national voiceprint database and provincial voiceprint database, and affect the efficiency of voiceprint recognition

Embodiment Construction
[0041] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0042] The main solution of the embodiment of the present invention is: the synchronization terminal receives the audio synchronization instruction; reads the provincial audio information from the provincial voiceprint database according to the audio synchronization instruction, and reads the provincial audio information from the national voiceprint database according to the audio synchronization instruction. Read national audio information; compare each piece of provincial audio information with each piece of national audio information in turn; if the similarity between the provincial audio information and the national audio information is less than the preset synchronization threshold, save the provincial audio information to the national voiceprint database.

The invention discloses an audio data synchronization method; the audio data synchronization method is applied to an audio data synchronization device; the audio data synchronization device comprisesa synchronization terminal; the method comprises the steps: receiving an audio synchronization instruction by the synchronization terminal ; reading provincial audio information from a provincial voiceprint library according to the audio synchronization instruction, and reading national audio information from a national voiceprint library according to the audio synchronization instruction; comparing each piece of provincial audio information with each piece of national audio information in sequence; and if the similarity between the provincial audio information and the national audio information is smaller than a preset synchronization threshold, storing the provincial audio information in the national voiceprint library. The invention further discloses a device and a computer readable storage medium. According to the invention, the national voiceprint library and the provincial voiceprint library can be synchronized, the redundancy of data of the national voiceprint library and the provincial voiceprint library is reduced, and the recognition efficiency of the national voiceprint library and the provincial voiceprint library is improved.
Description
technical field [0001] The invention relates to the technical field of public safety, in particular to an audio data synchronization method, device and computer-readable storage medium. Background technique [0002] At present, the voiceprint recognition technology usually first obtains the voice information of the suspect, extracts the voiceprint information in the voice information, compares the voiceprint information with the data in the public security voiceprint database, and obtains the comparison result; among them, the public security voiceprint The library includes the national voiceprint library and the provincial voiceprint library. The national voiceprint library and the provincial voiceprint library will be updated and stored in real time, which will cause the audio information in the national voiceprint library and the provincial voiceprint library to be different. , It is easy to miss some audio information, and even affect the detection of the case, which wil...
