US 2022/0068260 A1 · DEVICE AND METHOD FOR CLARIFYING DYSARTHRIA VOICES

Abstract

A device and a method for clarifying dysarthria voices is disclosed. Firstly, a dysarthria voice signal is received and framed to generate dysarthria frames. Then, the dysarthria frames are received to retrieve dysarthria features. Finally, the dysarthria features are received. Without receiving phases corresponding to the dysarthria features, the dysarthria features are converted into an intelligent voice signal based on an intelligent voice conversion model. The intelligent voice conversion model is not trained by the dynamic time warping (DTW). The present invention avoids the phase distortion of the voice signal and provides more natural and clarified voices with low noise.

Dependent claims

A device for clarifying dysarthria voices comprising:

a first framing circuit configured to receive and frame a dysarthria voice signal to generate dysarthria frames;
a first feature extracter coupled to the first framing circuit and configured to receive the dysarthria frames and extract dysarthria features from the dysarthria frames;
and
an intelligent voice converter coupled to the first feature extracter and configured to receive the dysarthria features, wherein the intelligent voice converter is configured to convert the dysarthria features into an intelligent voice signal based on an intelligent voice conversion model without receiving phases corresponding to the dysarthria features;
wherein the intelligent voice conversion model is not trained based on dynamic time warping (DTW).
