[0003] However, using the above-mentioned method to give the entire recording material to experts for comparison from beginning to end, it takes a lot of energy and takes a long time; in addition, when the suspect has an accent or dialect, the expert cannot understand In some cases, it will affect the judgment result. It is not convenient enough for translators to compare with experts or need translators to record and give to experts.

[0057] The data structure of the marked content is as follows:

[

[0058] {tag:'Hello',start:1818,end:3456},

[0059] {tag:'The weather is good today',start:3933,end:7020},

[0060] {tag:'ong4',start:8334,end:8640}

];

[0061]Its parsing of the wavf audio format is as follows: the first 44 bytes are analyzed according to the standard wav header, and information such as the audio file format, sampling rate, sampling accuracy, pcm encoding format, and pcm data length can be obtained. The length of the 44-byte wav header plus The total data length byte of pcmdata above is the offset address of the marked content, until the last byte of the file, and this part of the content is the content marked information.

[0062] 205. Acquire the audio in the audio format, and compare the marked parts optionally.

[0063] It should be noted that the marked part may include audio clips that are useful or useless to the staff, therefore, any desired clip can be selected for comparison an...

Abstract

The application discloses an audio comparison method, device and equipment. The method comprises the steps of obtaining to-be-identified audio frequency; marking a time period in which the to-be-identified audio frequency needs to be translated; generating a required audio format for the marked audio frequency; and acquiring the audio frequency in the audio format, and optionally selecting an annotation part for comparison. According to the method, the content needing to be compared is reduced in a mode of marking the time period in which translation is needed, and the comparison duration is shortened.

Description

technical field [0001] The present application relates to the technical field of audio recognition, in particular to an audio comparison method, device and equipment. Background technique [0002] In the voiceprint recognition of suspects in the public security and judicial fields, if it cannot be automatically recognized by the system or the case is special, experts may need to manually compare and analyze the speech of the test material and the sample speech to determine whether the two speeches belong to the same person. conclusion. [0003] However, using the above-mentioned method to give the entire recording material to experts for comparison from beginning to end, it takes a lot of energy and takes a long time; in addition, when the suspect has an accent or dialect, the expert cannot understand In some cases, it will affect the judgment result. It is not convenient for translators to compare with experts or need translators to record and give to experts. Contents o...
