Method Details

onPartialResult

void onPartialResult(String transcript)

Best-effort transcript while the user is still speaking. May fire many times before onResult(String, float, String[]). Skip overriding if RecognitionOptions.setPartialResults(false) was passed.

onResult

void onResult(String transcript,
 float confidence,
 String[] alternatives)

Final transcript for a single utterance. confidence is in [0.0, 1.0] when the platform supplies one, or -1 when it doesn't. alternatives may be empty.

onEnd

void onEnd()

Recognition session ended (timeout, mic released, or SpeechRecognizer.stop()). No more callbacks will fire.

onError

void onError(Throwable t)

Recognition failed (no permission, no network for online engines, hardware error).
