Abstract
An analysis processor applies an analysis process to input speech data thereby to obtain block lengths for respective attributes of voiced sound, voiceless sound and silence. A block data splitter splits the input speech data into blocks having the block lengths dependent on the respective attributes. A block data memory sequentially stores speech data split by the block data splitter as block speech data and the block lengths. A connection data generator generates connection data for connecting the adjacent block speech data each other at every moment by using the block speech data. A connection data storing portion sequentially stores the connection data. A connection order generator generates block connection order of the block speech data and the connection data at every moment according to at least the block lengths output sequentially from the block data storing portion and extension scaling factors in time for the respective attributes. A speech data connector connects sequentially the block speech data and the connection data based on the block connection order. Accordingly, the speed of output speech can be instantly changed in response to an instruction of an operator.
