PURPOSE:To generate a synthesized voice of high quality with good understanding and high naturalness by finding the understanding difficulty of each word of an input character string, controlling the rhythm of the synthesized voice according to the found difficulty and controlling the syllable clearness. CONSTITUTION:A KANJI (Chinese character) and KANA (Japanese syllabary) mixed sentence which is inputted from an input part 10 is divided into respective words by a word division processing part 21 in a character string analysis part 20 by referring to a Japanese dictionary 14a and the understanding difficulty of each word is calculated. When a word divided by the processing part 21 is a word divided matching the storage contents of the dictionary 14a, a processing part 22 performs identical type word selection processing and outputs the result to a rhythm processing part 23. When not, on the other hand, a KANJI dictionary 14b is referred to and the word is converted by a processing part 24 into rendering, which is given an accent by a processing part 25 and outputted to the processing part 23. The processing part 23 calculates a rhythm parameter by using a memory 15 according to the understanding difficulty and performs rhythm limitation processing. A generation part 26 receives the parameter and performs the control processing of syllable clearness according to the understanding difficulty by referring to a dictionary 16, and a voice is synthesized 12 and outputted 13. |
