Hello!
I'm trying to use the Speech Recognition API via JavaObjects and Reflection library.
After some hours of research, i finally made (mostly) working version.
This is my Service:
The Service is created once the application is started, the Listen event might be called by a button or a TCP message. But now, the problem:
When i first wrote this code (in the Main activity, not in a service) everything worked really fast - but in the service module the events: 1. getting dispatched very slow, sometimes there is a delay of about 2-3 seconds and 2. some events won't get dispatched - but only sometimes. In example the onError/onEndOfSpeech/onResults event.
Is there a problem with my code, or with the service?
Is there a way to enhance the speed of this service?
