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, wherein the plurality of the partial voice instruction recognition processing means are dispersed to the user system and the center system.

Abstract
High recognition capability is obtained even with voice input from a user terminal low in power consumption. A user system (1) incorporating a voice instruction recognition processing portion (4) and a transmission control portion (6) is connected to a center system (2) incorporating a reception control portion (7), a voice instruction recognition processing portion (5), and an output control portion (8) through a communication line (3). 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 (4, 5). This prevents decrease of a recognition rate like the case of disposing a voice analysis recognition processing function only on the center system (2) side. Also, there is eliminated 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 (1) side, and a processing load of the user system (1) side is decreased. This makes it possible to accept a voice instruction with a large lexis even if the user system (1) is a mobile device such as cell phones that are low in power consumption.

12. A user terminal comprising:
-
phoneme recognition means for recognizing an inputted voice per phoneme and creating a phonemic lattice; and
transmission control means for transmitting the phonemic lattice through a communication line.

-
13. A center system for transmitting and receiving information to/from a user system through a communication line, comprising:
-
reception means for receiving a phonemic lattice transmitted through the communication line;
a lexical grammar memory for storing lexical grammar; and
language processing means for performing language processing of the phonemic lattice with use of the lexical grammar.
