Abstract

This paper proposes a framework for prosody conversion of emotional speech based on LIBSVM support vector regression model and PAD three dimensional emotion model. We design an emotional speech corpus including 11 kinds of emotional utterances. Each utterance is labeled the emotional information with PAD value. A five-scale tone model is employed to model the pitch contour of emotional speech at the syllable level. A LIBSVM SVR-based prosody conversion model is proposed to realize the transformation of pitch contour, duration and pause duration of emotional speech according to the PAD values of emotion and context information of text. Speech is then re-synthesized with the STRAIGHT algorithm by modifying pitch contour, duration and pause duration, and is compared with the results obtained by the generalized regression neural network. Experimental results show that the modified speech achieves 3.8 of average Emotional Mean Opining Score (EMOS).
