The invention discloses a training method and device of a voiceprint recognition model, electronic equipment and a storage medium. The method incudes: acquiring a training set which comprises user audio data; inputting the acoustic feature vector corresponding to each audio data into a voiceprint recognition model to obtain the acoustic feature vector corresponding to each audio data in the training set and predicted probability distribution; calculating cross entropy loss according to the predicted probability distribution corresponding to each audio data in the training set and the real probability distribution corresponding to each audio data; calculating central loss according to the voiceprint feature vector corresponding to each audio data in the training set and the reference voiceprint feature vector corresponding to user identification; updating the model parameters of the voiceprint recognition model according to the cross entropy loss and the central loss. By the training method, the voiceprint fea
