Patent ID: 7225134

Claim:
A voice-input communication system having a user system with a user terminal and a center system being connected to the user system through a first communication line for sending an instruction from the user terminal to the center system, the voice-input communication system comprising: voice instruction recognition processing means composed of a plurality of partial voice instruction recognition processing means having different functions for recognizing an instruction content from a result of waveform analysis of an inputted voice instruction; phonation instruction means for creating a voice synthesis control parameter for a phonation content to be phonated by a user and transmitting the parameter to the user system; voice synthesis means for creating a synthetic voice with the phonation content based on the voice synthesis control parameter; waveform analysis means provided for extracting characteristics of an inputted voice through analysis of a waveform of the inputted voice; and speaker recognition means for recognizing a speaker based on the characteristics of the inputted voice, wherein the plurality of the partial voice instruction recognition processing means are dispersed to the user system and the center system.
