Abstract:
A speaker confirmation method and device. The method comprises: obtaining a second voice (S1); converting a first voice obtained in advance and the second voice into a corresponding first sound spectrogram and second sound spectrogram (S2); performing feature extraction on the first sound spectrogram and the second sound spectrogram by using a convolutional neural network to obtain corresponding first features and second features (S3); performing feature extraction on the first features and the second features by using a time delay neural network to obtain corresponding third features and fourth features (S4); and confirming a speaker according to the third features and the fourth features (S5).
