PROBLEM TO BE SOLVED: To achieve cost reduction by eliminating rhythm processing, shortening processing time and suppressing the increase of a memory capacity. SOLUTION: A phonemic sequence output part 2 outputs the phonemic sequence of phonemic symbols identical with the phonemic sequence in which input text information is decomposed and which is stored in the speech database 1 to a phonemic sequence waveform selection part 3. The phonemic sequence waveform part 3 extracts a candidate phonemic sequence from the speech database 1 while successively paying attention to each phonemic sequence inputted from the phonemic sequence output part 2, and selects and outputs the optimal phonemic sequence. A fundamental frequency pattern generating means 4 divides the input text information into a plurality of phonemic sequences having one accent, and generates a fundamental frequency pattern about this. A selection means 5 narrows the number of candidate phonemic sequences by comparing the fundamental frequency of the waveform data of each candidate phonemic sequence with the value of the fundamental frequency pattern, discriminating whether the difference between the two is in a prescribed range, and discriminating further whether each candidate phonemic sequence satisfies a prescribed reference. |
