Self-adaptive gain intelligent interrogation recording device and recording method

Abstract

The invention discloses a self-adaptive gain intelligent interrogation record device and method. The method comprises the steps that S1, sound source collection is carried out through a multi-channel sound collection device; s2, the sound source is analyzed, and corresponding text information is generated; s3, based on the target text information, text file data are generated and output; the self-adaptive sound source gain process provided by the invention is not limited by a specific field environment structure, hardware sound collection equipment and behaviors of a spokesman, and sound source gain which contributes to improving the recognition effect can be dynamically carried out on the acoustic signal of the spokesman in real time, so that the tuning cost of a traditional method is avoided, and the real recording process is guaranteed; meanwhile, acoustic signal collection and crosstalk processing processes are comprehensively considered, and crosstalk channels are identified and filtered in real time through effective acoustic feature extraction and a crosstalk identification strategy model, so that the occurrence of crosstalk phenomena is remarkably reduced; and meanwhile, the method can be effectively suitable for recording sites of various practical applications.

Description

technical field [0001] The invention relates to the field of audio processing, in particular to an adaptive gain intelligent interrogation recording device and recording method. Background technique [0002] At present, during the court hearing, the speech information of the judges and the parties need to be recorded, and after the trial is over, it will be compiled into a court transcript, which will be signed and confirmed by the parties for archiving. In the traditional trial process, a clerk will be assigned. During the entire trial process, the clerk will record the speeches of each role. After the recording is completed, it needs to be organized into court transcripts in a fixed format. The whole process has certain requirements on the typing level of the clerk, and also requires a certain understanding of the content of the case in court, and a certain degree of professional depth in laws and regulations. During this process, due to the different typing speeds of the...

Problems solved by technology

[0010] The present invention is to overcome the following phenomena in the prior art that are prone to occur in the recording environment of the applied speech recognition system: 1) it is difficult for a speaker with a small voice to be picked up and recognized; 2) a speaker with a loud voice is easy to be strung into other acquisition devices Cause interference; 3) Multiple speakers speaking at the same time are prone to crosstalk and drop words. 4) The on-site environment has poor noise filtering effect, resulting in a large number of interference sound sources, which leads to problems such as confusion in the recognition results. A feed-forward memory network based on The multi-channel anti-crosstalk dynamic planning strategy greatly solves the problem of low sound source loss and crosstalk of each channel, effectively improving the effect of speech recognition
