VOICE SYNTHESIZING DEVICE

摘要

PURPOSE: To improve the naturality of synthesized voice by maintaining the specified phoneme continuation time and pause length of single sound and forming phoneme symbol strings and vocal sound and rhythm control parameters. CONSTITUTION: Processing to limit the number of the syllables of one word tone is executed according to the instruction of a speed setting section 10 in a text structure deforming section 8. Next, the phoneme and rhythm control parameter value information is so determined as to extend and contract the phoneme continuation time and pause length of single sound at the ratios according to the speed. This determination is executed by a time length determining section 11 according to the instruction from a speed setting section 10. The phoneme and rhythm symbol strings obtd. from the text structure changed in the pause insertion position by the text structure deforming section 8 and the phoneme and rhythm control parameters formed by the instruction of high-speed utterance by the time length determining section 11 are simultaneously formed and are outputted to a parameter forming section 6. The speed synthesis parameters are formed in parameter formation in such a manner. The parameter systems are sent to a synthesizer to obtain the synthesized voices according to the assigned speed.
