When recognizing with multiple grammars enabled with VoCon 3200 V3, recognition quality begins to decrease.


Multi-context recognition with VoCon 3200 V3 may or may not return matches for all contexts (grammars) for each request and results are unordered. The result with the highest confidence may be skipped.


Fixed in ProfileKit build and SpeechKit build
