This paper describes the method of generation of intonated speech for natural speech synthesis using prosody generation model. The effect of pitch modification through pitch contour stylization for parameter extraction and time scale modification for its implementation has been mentioned. An approach for close-copy syllabic stylization has been described.
In the latter part, algorithm for implementation of time scale modification with necessary approximation for sinusoidal signal has been mentioned. Experimental results of applying the technique for pitch modification on Bengali sentence have been shown. The output shows satisfactory performance of sound quality after necessary pitch modification to make synthetic speech natural.
