内容摘要:

 

A universal principle, where a statistics embodied in a Maximum Likelihood (ML) Hidden Markov Model (HMM) is used for searching the optimal sequence of real samples (examples), to creating a high quality, Text-to-Speech (TTS) system and a photo-realistic talking head. Both systems have many human-machine interface applications, e.g. reading email, news stories, or eBooks, acting as an intelligent agent, a language learning tutor, etc. and a lively, lip-sync talking head can make such an interface even more engaging. In this talk we will concentrate more on the photo-realistic talking head which consists of two parts, training and synthesis. In training, an audio/visual database is first collected to train statistical HMM. In synthesis, trained HMM is used to generate (synthesize) smooth mouth trajectories from given natural or Text-to-Speech (TTS) synthesized speech. The rendered talking head is photo-realistic. Additionally, facial expressions like eye blinking/gazing, eyebrow movement, smiles or other emotions can be learned and rendered with collected and labeled data.
