Speech input communication system, user terminal and center system
First Claim
1. 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, whereinthe plurality of the partial voice instruction recognition processing means are dispersed to the user system and the center system.

Abstract
A user system incorporating a voice instruction recognition processing portion and a transmission control portion is connected through a communication line to a center system incorporating a reception control portion, a voice instruction recognition processing portion and an output control portion. Processing for obtaining a voice instruction content based on a waveform analysis result of the voice instruction is shared by voice instruction recognition processing portions. This share prevents decrease of a recognition rate occurred in the case of disposing a voice analysis recognition processing function only on the center system. The share also eliminates waiting time for transfer of lexical grammar data generated in the case of disposing the voice analysis recognition processing function only on the user system. Further, a processing load of the user system is decreased. Thus, high recognition capability is obtained even with voice input from a user terminal low in power consumption.
