PRB: Destroying vocabulary stops event notification

The information in this article applies to:

  • SpeechKit 9


No recognition events are detected once a vocabulary is destroyed.


Vocabularies can be enabled and disabled as needed by the application. Once a vocabulary is destroyed however, the destructor releases the client reference preventing future event callbacks from firing.

Vocabulary destructors in client objects are updated to eliminate the possible release. Compiling C++, C++Builder, Delphi, Java, and .NET applications with the update libraries eliminates the problem.


Fixed in SpeechKit 9 build
