Abstract :
In the present paper, a method for the real-time conversion of whisper to normal phonated speech in Chinese through a multiple excited linear prediction (MELP) analysis-by-synthesis codec is discussed. In the analysis codec processing of whisper speech, parameters from unchanged MELP model are changed, such as the pitch and the formants which aims to reconstruct the target phonated speech using the synthesis codec. Subjective evaluation results show the effectiveness of the technique.
