It is hence difficult to design one especially for speech synthesis. To alleviate these drawbacks, establishing an end-to-end speech synthesis system, we propose to use character-level word2vector and recurrent neural networks (RNNs) to directly convert input character sequences into latent linguistic feature vectors for context dependent. In the end, we use a mixed English-Chinese speech synthesis system to test this idea. Experimental results show that proposed approach provides comparable performance with conventional NLP parser-based methods.
