  • Device and method for generating synchronous corpus
    Patent number: 11222650
    Abstract: A device and a method for generating synchronous corpus is disclosed. Firstly, script data and a dysarthria voice signal having a dysarthria consonant signal are received and the position of the dysarthria consonant signal is detected, wherein the script data have text corresponding to the dysarthria voice signal. Then, normal phoneme data corresponding to the text are searched and the text is converted into a normal voice signal based on the normal phoneme data corresponding to the text. The dysarthria consonant signal is replaced with the normal consonant signal based on the positions of the normal consonant signal and the dysarthria consonant signal, thereby synchronously converting the dysarthria voice signal into a synthesized voice signal. The synthesized voice signal and the dysarthria voice signal are provided to train a voice conversion model, retain the timbre of the dysarthria voices and improve the communication situations.
