The accurate modelling of fundamental frequency, or F0, in HMM-based speech synthesis is a critical factor in achieving high quality speech. However, it is also difficult because F0 values are normally considered to depend on a binary voicing decision such that they are continuous in voiced regions and undefined in unvoiced regions. A widely used solution is to use a multi-space probability distribution HMM (MSDHMM), which directly models discontinuous F0 observations. An alternative solution… CONTINUE READING
