VOICE RECOGNITION TERMINAL, VOICE RECOGNITION SERVER, AND VOICE RECOGNITION METHOD FOR PERFORMING PERSONALIZED VOICE RECOGNITION
First Claim
1. A voice recognition terminal, comprising:
- a feature extraction unit for extracting feature data from an input voice signal;
an acoustic score calculation unit for calculating acoustic model scores using the feature data; and
a communication unit for transmitting the acoustic model scores and state information to a voice recognition server in units of one or more frames, and receiving transcription data from the voice recognition server,wherein the transcription data is recognized using a calculated path of a language network when the voice recognition server calculates the path of the language network using the acoustic model scores.
