Document Type and Number:
WIPO Patent Application WO/2021/000498
Kind Code:
A1
Abstract:
A composite speech recognition method, device, equipment, and a computer-readable storage medium. The method comprises: detecting a composite speech within a preset range (S10), acquiring a voice signal of the composite speech (S20); performing short-time Fourier transform with respect to the voice signal, generating a time-frequency graph of a composite speech signal (S30); extracting multiple spectrums of the time-frequency graph on the basis of a preset capsule network model, acquiring coefficients of the spectrums (S40), calculating vector moduli of the coefficients, and determining the type of the composite speech on the basis of the vector moduli (S50).
