PRB: Recognizing from wave file seems to ignore grammars
The information in this article applies to:
- SpeechKit 3
Using the Record method to recognize from a wave file appears to use dictation recognition mode rather than recognizing from other active grammar vocabularies.
The Microsoft SAPI5 recognizer appears to use dictation mode even though other grammars may be active. The Record method automatically adds (if one does not exist) and enables a dictation vocabulary. If the application adds and enables other grammars, they do not appear to be factored in the recognition context.
Fixed in SpeechKit 3 SR1. When using Record with non-live audio sources, the ChantSR component only adds and enables a dictation vocabulary if no other vocabulary is active.
