摘要：
The present invention relates to a method and device for performing real-time conversion of whispered speech into synthetic natural speech, through efficient and compact parametric signal analysis, signal modelling, and signal synthesis techniques. More particularly, according to the present invention, the whispered speech signal, which is produced by the human phonetic apparatus without the contribution of the vocal folds in the larynx, is taken as input and synthetic periodic signals components are implanted in selected regions of the whispered signal, thereby restoring the missing periodic components as a consequence of inoperative or non-existing vocal folds. This is done in such a fashion as to enhance the linguistic content of the speech, to improve the voice projection, and to convey elements of the sound signature of a specific speaker.
