Abstract

In this paper, we propose HMM-based text-to-speech (TTS) using sub-band basis spectrum model (SBM). SBM can represent vocal tract spectra and phase char-acteristics by a linear combination of sub-band basis vectors. Some reports suggest that analysis-synthesized speech based on SBM is close to natural speech and SBM can perform effectively in TTS. Therefore, the SBM framework is expected to have good effects on HMM-based TTS by improving speech quality. Subjective ex-perimental results show that the proposed method im-proves speech quality in some conditions.
