Method and Device for Selecting Acoustic Units and a Voice Synthesis Method and Device

摘要

A method for selecting acoustic units each of which contains a natural speech signal and symbolic parameters involves a stage ( 4 ) for determining at least one target symbolic unit sequence; a stage ( 5 ) for determining a contextual acoustic model sequence corresponding to the target sequence; a stage ( 6 ) for determining an acoustic template on the basis of the contextual acoustic model sequence and a stage ( 7 ) for selecting the acoustic unit sequence according to the acoustic template applied to the target symbolic unit sequence. The invention is used for voice synthesis.
