PURPOSE: To generate a natural synthesized speech including a place name by generating the synthesized speech corresponding to an input sentence on the basis of phoneme information on the input sentence and rhythm information including an accent type. CONSTITUTION: A KANJI(Chinese character)-KANA(Japanese syllabary) mixed sentence including a place name is supplied as the input text to a text analysis part 10 and a morpheme analysis part 1 takes a morpheme analysis and outputs respective morphemes while a reading (phoneme information), part of speech, and an accent type are added. In principle, no accent type is added to the place name, but an accent type is given to a special place name described in a place name dictionary. A reading pronunciation symbol generation part 2 converts the readings of the respective phonemes into pronunciation symbol sequences, and rhythm information is determined by a rhythm information generation part 3 and included in the pronunciation symbol sequences. For a place name to which no accent type is given, its accent type is determined on the basis of its index and phoneme information, On the basis of the outputted phoneme information and rhythm information, the synthesized speech corresponding to the input sentence is generated. |
