<P>PROBLEM TO BE SOLVED: To provide a speech synthesizer capable of performing speech synthesis which is naturally heard by using a naturally spoken voice DB. <P>SOLUTION: The speech synthesizer includes a balance sentence voice DB 34 wherein language information is labeled, the naturally spoken voice DB 42, a waveform generation part 36 and a speech signal synthesis part 38 which composes a speech signal of an input XML 30 given non-language information and the balance sentence voice DB 34, a candidate selection part 44 which selects a plurality of candidates for similar voice data from the naturally spoken voice DB 42 as to respective parts of an acoustic target 40 outputted from the speech signal synthesis part 38, a filter part 48 which calculates metric features from the candidate array 46 and selects information matching the non-language information given to the input XML 30 most, and a waveform generation part 52 which composes a synthesized speech signal 54 by connecting the selected natural speaking data. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
