| Abstract(in English) | This paper describes a technique for controlling voice quality of synthetic speech using multiple-regression hidden semi-Markov model (MRHSMM). To achieve voice quality control with a small amount of training data, we incorporate a speaker adaptation technique from an average voice model into MRHSMM-based voice quality control. In the proposed technique, we first adapt the average voice model to respective training speakers using a small amount of adaptation data. Then, using obtained speaker-adapted HSMMs and low-dimensional voice quality control vector for each training speaker, the regression matrices of MRHSMM are estimated based on least square method and maximum likelihood estimation. We attempt to control voice quality of synthetic speech using 20 speakers' data of 50 sentences for each speaker. From results of subjective evaluation, we show that the proposed technique can control several voice qualities of synthetic speech. Furthermore, we propose model interpolation technique for the MRHSMMs and show its evaluation results. |
