Microsoft Speech SDK
SpLexicon
The SpLexicon automation object provides access to lexicons. Lexicons contain information about words that can be recognized or spoken.
SAPI defines two types of lexicons. The first is the application lexicon. Application lexicons are the words that all applications can use. They are installed by speech-enabled applications and are read-only. As a result, the application lexicons may vary slightly among computers. The second type is the user lexicon. User lexicons store words specific to a speech user.
An SpLexicon object includes the user lexicon and all application lexicons available on the computer. Calls to SpLexicon methods may return data from several different lexicons.
The SpUnCompressedLexicon object represents a single application lexicon.
