VOICE SYNTHESIZER

PURPOSE: To correct the fault of a point pitch model, to generate a natural pitch pattern and to produce a high quality synthesized sound in a voice synthesizer. CONSTITUTION: The voice synthesizer is provided with a first database section 21 which stores accent type point pitch patterns, a second database section 24 which stores the rule corresponding to the combination of the accent type and phoneme and a pitch pattern generating section 8 which retrieves a point pitch pattern corresponding to the paragraph, that is an object of the voice synthesis, from the section 21 and generates a new point pitch pattern based on the rule of the section 24 from the obtained point pitch pattern. Thus, pitches are given to not only the vowel centroid point but also to a phoneme boundary and the naturality in a head word in a synthesized sound and the vowel chain in an accent kernel is improved.
