I'm not 100% sure of this, however since it's been so long since you posted, I may as well give it a shot. It seems that you are doing something wrong in the code. As the commenter said, it would be helpful if you actually posted the code that is returning this error. However, in the source code for the Android speech recognition service found here:

http://source-android.frandroid.com/frameworks/base/core/java/android/speech/RecognitionService.java we have a function called dispatchStopListening which seems to end the listening process. However, before it actually ends it, there are a few checks for illegal states, including this:

else if (mCurrentCallback.mListener.asBinder() != listener.asBinder()) {
            listener.onError(SpeechRecognizer.ERROR_RECOGNIZER_BUSY);
            Log.w(TAG, "stopListening called by other caller than startListening - ignoring");
        }

This seems to imply that you are trying to end the listening process by some other guy than you started it with, which raises this error. I hope this helps, but it would be extremely beneficial if you posted the code.
