Embodiment Construction

[0057] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0058] Such as figure 1 As shown, it is a flow chart of the speaker role separation method in the interrogation scene of the embodiment of the present invention, including the following steps:

[0059] Step 101, acquire voice data in an interrogation scene.

[0060] Step 102, extracting character recognition features of each analysis unit from the voice data, each analysis unit only includes one speaker's voice segment.

[0061] Each analysis unit is a complete effective speech segment. Specifically, when each analysis unit is determined, the speech data can be firstly subjected to endpoint detection to obtain each effective speech segment, and then the effective speech segment is segmented , to get each analy...

Abstract

The invention discloses a speaker's role separation method and system in a trial scene, and the method comprises the steps: obtaining the voice data in the trial scene; extracting a role recognition feature of each analysis unit from the voice data, wherein each analysis unit just comprises a voice segment of one speaker; sequentially inputting the role recognition features of each analysis unit into a pre-built speaker's role recognition mode, and determining a speaker's role corresponding to the current analysis unit according to the model output, wherein the speaker's role comprises an interrogating person and an interrogated person. According to the invention, the method and system can achieve the accurate recognition of the speaker's role in the trial scene.

Description

technical field [0001] The invention relates to the field of voice signal processing, in particular to a speaker role separation method and system in an interrogation scene. Background technique [0002] At present, a large number of interrogation cases are handled across the country every year, and the procuratorate needs to record the interrogation situation and the content of the questions and answers in detail during the interrogation, and the related work consumes a lot of manpower. At the same time, there are omissions or inaccurate records due to personal reasons, and the development of speech recognition technology provides an effective way to solve this problem. [0003] Most of the current interrogation recordings use ordinary pickup equipment, which may be one or more. The equipment is generally placed on the wall or on the table in the interrogation room to record the voice of the entire interrogation process. However, this interrogation recording device has the...
