• Method Detail

  • beginningOfSpeech

    public void beginningOfSpeech()
                           throws RemoteException

    The service should call this method when the user has started to speak.

    Throws:

    RemoteException

  • bufferReceived

    public void bufferReceived(byte[] buffer)
                        throws RemoteException

    The service should call this method when sound has been received. The purpose of this function is to allow giving feedback to the user regarding the captured audio.

    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.

    Throws:

    RemoteException

  • endOfSpeech

    public void endOfSpeech()
                     throws RemoteException

    The service should call this method after the user stops speaking.

    Throws:

    RemoteException

  • error

    public void error(int error)
               throws RemoteException

    The service should call this method when a network or recognition error occurred.

    Parameters:

    error - code is defined in SpeechRecognizer

    Throws:

    RemoteException

  • partialResults

    public void partialResults(Bundle partialResults)
                        throws RemoteException

    The service should call this method when partial recognition results are available. This method can be called at any time between beginningOfSpeech() and results(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.

    Parameters:

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

    Throws:

    RemoteException

  • readyForSpeech

    public void readyForSpeech(Bundle params)
                        throws RemoteException

    The service should call this method when the endpointer is ready for the user to start speaking.

    Parameters:

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

    Throws:

    RemoteException

  • results

    public void results(Bundle results)
                 throws RemoteException

    The service should call this method 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

    Throws:

    RemoteException

  • rmsChanged

    public void rmsChanged(float rmsdB)
                    throws RemoteException

    The service should call this method when 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

    Throws:

    RemoteException
