1. A speech recognition method, comprising:
- receiving a phonetic sequence output by a phonetic recognizer;
matching the phonetic sequence with one of a plurality of reference phoneme sequences stored in a reference list that matches closest thereto, wherein at least one of the plurality of reference phoneme sequences stored in the reference list includes additional information with respect to a phonetic sequence that is capable of being output by the phonetic recognizer.

Abstract
A speech recognition method includes a step of receiving a phonetic sequence output by a phonetic recognizer. The method also includes a step of matching the phonetic sequence with one of a plurality of reference phoneme sequences stored in a reference list that matches closest thereto. At least one of the plurality of reference phoneme sequences stored in the reference list includes additional information with respect to a phonetic sequence that is capable of being output by the phonetic recognizer.
