Getting a text to speech synthesis (TTS) system to speak lively animated stories like a human is very difficult. To generate expressive speech, the system can be divided into 2 parts: predicting expressive information from text; and synthesizing the speech with a particular expression. Traditionally these blocks have been studied separately. This paper proposes an integrated approach, sharing the expressive synthesis space and training data across the two expressive components. There are several advantages to this approach, including a simplified expression labelling process, support of a continuous expressive synthesis space, and joint training of the expression predictor and speech synthesiser to maximise the likelihood of the TTS system given the training data. Synthesis experiments indicated that the proposed approach generated far more expressive speech than both a neutral TTS and one where the expression was randomly selected. The experimental results also showed the advantage of a continuous expressive synthesis space over a discrete space. © 2013 IEEE.
