The invention provides a cross-channel voiceprint recognition method and device, equipment and a storage medium, and the method comprises the steps: obtaining to-be-recognized voiceprint audio data, the to-be-recognized voiceprint audio data being collected in channels in a set channel set, and the set channel set comprising at least two different channels; inputting the voiceprint audio data to be recognized into a preset cross-channel voiceprint recognition model to obtain a voiceprint audio data processing result, and performing voiceprint audio data recognition according to the voiceprint audio data processing result, wherein the cross-channel voiceprint recognition model is obtained by training voiceprint audio data collected in the set channel set through multiple iteration processes, and model parameter training is carried out by adopting voiceprint audio data collected in two different channels in each iteration process. According to the technical scheme of the invention, the recognition accuracy of cross-channel voiceprint recognition can be improved.
Description
technical field [0001] The invention relates to the field of geostatistical methods, in particular to a cross-channel voiceprint recognition method, device, electronic equipment and non-transitory computer-readable storage medium. Background technique [0002] In recent years, with the in-depth research of voiceprint recognition technology, the voiceprint recognition system has achieved satisfactory performance under single channel conditions. However, in practical applications, voice signals can be transmitted through different channels, such as network channels, telephone channels, and so on. This channel difference will produce different degrees of distortion on the voice signal, which will affect the performance of the voiceprint recognition system. For example, in the registration phase, the user's voice is collected by the network channel; in the recognition phase, the user's voice is collected by the telephone channel. At this time, due to channel mismatch, the perf...
