1. A voice recognition apparatus comprising:
- a context model created by modeling recognition target context;
a model creator configured to classify the recognition target context according to a length of syllables, and to create a context model for each length of syllables; and
a voice recognizer configured to create a candidate group corresponding to a received voice signal based on an acoustic model and the context model for each length of syllables, calculate a length of a user'"'"'s speech based on a Begin of Speech (BoS) and an End of Speech (EoS), and apply a high reliability weight value to a candidate having a length of syllables corresponding to the length of speech.

6. A vehicle comprising:
-
a context model created by modeling each name included in a phone book; a model creator configured to classify the phone book according to a length of syllables of each name, and to create a context model for each length of syllables; and a voice recognizer configured to create a phone number candidate group corresponding to a received voice signal based on an acoustic model and the context model for each length of syllables, calculate a length of speech based on a Begin of Speech (BoS) and an End of Speech (EoS), and to respectively apply different reliability weight values determined according to the length of speech to phone number candidates in the phone number candidate group. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A control method of a vehicle, comprising:
-
creating a phone number candidate group corresponding to a received voice signal from a context model created by modeling each name included in a phone book; classifying the phone book according to lengths of names, and creating a context model for each of the lengths of the names; calculate a length of speech based on a Begin of Speech (BoS) and an End of Speech (EoS); determining reliability weight values according to the length of the user'"'"'s speech; and applying the reliability weight values according to lengths of syllables of phone number candidates selected from the context model for each of the lengths of the names. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
