Claim:
1. A method of controlling a voice recognition apparatus, the method comprising: generating a plurality of recognition tokens based on a voice signal received by the voice recognition apparatus; searching for a similar token and a peripheral token for each of the recognition tokens, from among a plurality of pre-stored tokens, the similar token being a pre-stored token having a high degree of similarity with the recognition token and the peripheral token being a pre-stored token previously used with the recognition token; generating a token network using the recognition tokens, the similar tokens, and the peripheral tokens; calculating a transition probability between the tokens constituting the token network; and generating text data for the received voice signal using the calculated transition probability, wherein, in response to a first recognition token not being present among the plurality of pre-stored tokens, the searching includes searching for the peripheral token corresponding to a second recognition token located just after the first recognition token.
