【発明の名称】テキスト音声合成装置
Document Type and Number:
Japanese Patent JP3034911
Kind Code:
B2
Abstract:
PURPOSE:To synthesize practical documents and voices which have a variety of voicing speeds by coupling the words of the whole sentence in the order of modification strength between adjacent words and forming a hierarchic structure, and calculating the extent of coupling between clauses and setting a pitch pattern and the pause length between breath groups. CONSTITUTION:A dividing means 21 divides an input sentence into respective words, a setting means 22 sets an accent type of each word and its rendering, and a rhythm control means 23 couples the words of the whole sentence in the order of modification strength between adjacent words to form the hierarchic structure. Then the extent of coupling between adjacent clauses is calculated from the hierarchic structure and the pitch pattern and the pause length between breath groups are set according to the extent of coupling between the clauses and the accent types of the respective words supplied from the setting means 22 to control the rhythm. Lastly, a parameter generating means 24 retrieves a synthesis unit corresponding to the rendering of each word supplied to a word rendering accent processing part 22 to output a time series of voice parameters. Consequently, the practical documents and the voices which has a variety of voicing speeds can be synthesized.
