METHOD OF SPEECH SYNTHESIS

摘要

A method of speech synthesis for reproduction of facial movements of a person with synchronized speech synthesis. The speech is put together of polyphones that are taken from a database. A databank is established containing polyphones with the polyphones belonging to facial movement patterns of the face of a first person. Polyphones from a second person are also registered and stored in the database. The duration of sound segments in corresponding polyphones in the databank and the database are compared and the facial movements in the databank are modified in accordance with the deviation. The modified facial movements are stored in the databank and related to the polyphone in question. These registered polyphones are then utilized to put together words and sentences at the same time as corresponding facial movements build up a face model from the modified facial movements in the databank.
