This paper describes construction of an HMM-based spontaneous speech
synthesizer and investigates effectiveness of the statistical models
in the system. In our system, cepstral features are modeled by HMMs and phoneme duration and fundamental frequency (F0) features are modeled by Quantification Theory (Type 1). These three models are trained with spontaneous lecture speech extracted from the Corpus of Spontaneous Japanese (CSJ). For comparison, we prepared a speech synthesizer where all models were trained with read speech. Spontaneity of the synthesized spontaneous speech was evaluated by subjective pair comparison tests. Experimental results show that the preference score for the synthesized spontaneous speech is significantly higher than that for the synthesized read speech. This implies that HMM-based speech synthesis using actual spontaneous utterances for model training is effective for producing spontaneous speech. Additional subjective evaluations were also conducted to analyze the effect of individual models used in our synthesizer on the impression of spontaneity. |
