PURPOSE:To easily correct the length of continuation time in a speech rule synthesizer. CONSTITUTION:A text analysis means 101 analyzes an inputted text and obtains an information relative to phonemes and rhythm. Based on the information, a pitch pattern generating means 102 generates the pitch pattern which indicates time variation of fundamental frequencies, a continuation time length generating means 103 generates the trains of continuation time length of each phoneme. An input means 111 inputs the pair of the phoneme trains and the continuation time length of each phoneme included in the phoneme train, a storage means 112 which stores the phoneme trains and the corresponding continuation time length trains. A waveform generating means 104 refers to the means 111 and 112 in accordance with the input of the phoneme trains and when a proper continuation time length train is retrieved, the continuation time length train from the means 103 is replaced by the continuation time length train retrieved from the means 112 and a replacement means 113 transmits the train to the means 104. |
