• Method Detail

  • onReadyForSpeech

    void onReadyForSpeech(Bundle params)

    Called when the endpointer is ready for the user to start speaking.

    Parameters:

    params - parameters set by the recognition service. Reserved for future use.

  • onBeginningOfSpeech

    void onBeginningOfSpeech()

    The user has started to speak.

  • onRmsChanged

    void onRmsChanged(float rmsdB)

    The sound level in the audio stream has changed. There is no guarantee that this method will be called.

    Parameters:

    rmsdB - the new RMS dB value

  • onBufferReceived

    void onBufferReceived(byte[] buffer)

    More sound has been received. The purpose of this function is to allow giving feedback to the user regarding the captured audio. There is no guarantee that this method will be called.

    Parameters:

    buffer - a buffer containing a sequence of big-endian 16-bit integers representing a single channel audio stream. The sample rate is implementation dependent.

  • onEndOfSpeech

    void onEndOfSpeech()

    Called after the user stops speaking.

  • onError

    void onError(int error)

    A network or recognition error occurred.

    Parameters:

    error - code is defined in SpeechRecognizer

  • onResults

    void onResults(Bundle results)

    Called when recognition results are ready.

    Parameters:

    results - the recognition results. To retrieve the results in ArrayList<String> format use Bundle.getStringArrayList(String) with SpeechRecognizer.RESULTS_RECOGNITION as a parameter. A float array of confidence values might also be given in SpeechRecognizer.CONFIDENCE_SCORES.

  • onPartialResults

    void onPartialResults(Bundle partialResults)

    Called when partial recognition results are available. The callback might be called at any time between onBeginningOfSpeech() and onResults(Bundle) when partial results are ready. This method may be called zero, one or multiple times for each call to SpeechRecognizer.startListening(Intent), depending on the speech recognition service implementation. To request partial results, use RecognizerIntent.EXTRA_PARTIAL_RESULTS

    Parameters:

    partialResults - the returned results. To retrieve the results in ArrayList<String> format use Bundle.getStringArrayList(String) with SpeechRecognizer.RESULTS_RECOGNITION as a parameter

  • onEvent

    void onEvent(int eventType,
               Bundle params)

    Reserved for adding future events.

    Parameters:

    eventType - the type of the occurred event

    params - a Bundle containing the passed parameters
