I have speech recognition now working with large lm. My app is designed to start speech recognition when user presses button and stop when hypothesis is retuned. In code below I am doing resumeRecognition and suspendRecognition. I then do multiple speaks via Flite.
1. From the log below it appears that every time Flite has finished speaking – Pocketsphinx has resumed recognition. Is there a way to prevent this?
2. From the log below I use Flite to say “error netfor: hand”. Then “Love”. And finally “Thirty”. I only hear “error netfor: hand”. Is there away to wait after each phase to make sure speech is complete as there is using Google TTS?
3. I am using speech punctuation “:” is this any problem with Flite?
