Title:
VOICEPRINT DETECTION METHOD, APPARATUS AND DEVICE BASED ON SHORT TEXT, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/177380
Kind Code:
A1
Abstract:
Disclosed are a voiceprint detection method, apparatus and device based on a short text, and a storage medium. The method comprises: training a preset deep neural network by means of a training sample; acquiring a speech signal to be recognized; preprocessing the speech signal to be recognized, and carrying out feature extraction on the preprocessed speech signal to obtain a mel-frequency cepstral coefficient; taking the mel-frequency cepstral coefficient as an input and transmitting same into the pretrained deep neural network, and acquiring an output vector of the deep neural network on a last full connection layer and taking same as a voiceprint vector of the speech signal; and comparing the voiceprint vector of the speech signal with a voiceprint vector prestored in a voiceprint model library, and outputting a voiceprint detection result according to a comparison result, wherein the training sample and the speech signal are both a short text. The present application solves the problems of a redundant speech signal, a large quantity of sample information and a high requirement for computing resources in an existing voiceprint detection method.
