Problems solved by technology

[0004] As the application becomes more and more widespread, some problems have also occurred, including the voiceprint recognition technology is vulnerable to the attacks of recording playback / speech synthesis / speech generation / speech conversion, which causes the recognition system to judge the voice of the non-real speaker as The voice of the speaker, which leads to the illegal intrusion of the application system and brings unexpected losses

Abstract

The invention relates to the technical field of voiceprint recognition and provides an audio data recognition method which comprises the following steps: acquiring audio data input by a user; cuttinga data segment of a preset length from the audio data; converting the data segment into voiceprint characteristics; on the basis of a preset GRU (Gated Recurrent Unit) neural network recognition model, recognizing the voiceprint characteristics, and confirming that the voiceprint characteristics belong to real human voice or replayed recorded voice. By adopting the method provided by the invention, real human voice or replayed recorded voice can be accurately recognized, anti-replay recognition on audio data input by a user can be achieved, and hostile attack can be prevented. In addition, theinvention further provides a human voice anti-replay recognition system.

Description

technical field [0001] The invention relates to the technical field of audio recognition, in particular to an audio data recognition method and a human voice voice anti-replay recognition system. Background technique [0002] Voiceprint recognition, a kind of biometric technology, also known as speaker recognition, has two types, namely speaker identification and speaker confirmation. Different tasks and applications will use different voiceprint recognition technologies. For example, identification technology may be required when narrowing the scope of criminal investigation, while confirmation technology is required for bank transactions. Voiceprint recognition is to convert the acoustic signal into an electrical signal, and then use a computer to identify it. [0003] With the development of computer technology, voiceprint recognition technology has been widely used in banking, finance, security and other fields. This technology has the characteristics of low cost and hi...
