This paper describes an emotional singing voice synthesis algorithm based on hidden Markov model. To express a particular emotion, the fundamental frequency (F0) contour of singing voice is modified by controlling the parameters consisting of vibrato extent, vibrato rate, overshoot, and preparation. Experimental results on the effectiveness of F0 contour modification in expressing a certain emotion...
This paper describes an algorithm to control the expressed emotion of a synthesized song. Based on the database of various melodies sung neutrally with restricted set of words, hidden semi-Markov models (HSMMs) of notes ranging from E3 to G5 are constructed for synthesizing singing voice. Three steps are taken in the synthesis: (1) Pitch and duration are determined according to the notes indicated...
