1. A distributed speech recognition system comprising:
- a terminal which decodes a feature vector that is extracted from an input speech signal into a recognized sequence of phonemes; and
a server which performs symbol matching on the recognized sequence of phonemes provided from the terminal and transmits a final recognition result to the terminal.

Abstract
Provided are a distributed speech recognition system, a distributed speech recognition speech method, and a terminal and a server for distributed speech recognition. The distributed speech recognition system includes a terminal which decodes a feature vector that is extracted from an input speech signal into a sequence of phonemes and generates the final recognition result by rescoring a candidate list provided from the outside; and a server which generates the candidate list by performing symbol matching on the recognized sequence of phonemes provided from the terminal and transmits the candidate list for the rescoring to the terminal.
