All Implemented Interfaces:

RecognitionListener

public class SpeechRecognizerDbmHandler
extends DbmHandler<Float>
implements RecognitionListener

Implementation of DbmHandler for SpeechRecognizer. Note: make sure you're calling AudioVisualization.onPause() when RecognitionListener.onEndOfSpeech() event called to stop visualizing.

Method Detail

startListening

public void startListening(Intent recognitionIntent)

Start listening for speech.

Parameters:

recognitionIntent - contains parameters for the recognition to be performed

See Also:

SpeechRecognizer.startListening(Intent)

stopListening

public void stopListening()

Stop listening for speech.

See Also:

SpeechRecognizer.stopListening()

innerRecognitionListener

public SpeechRecognizerDbmHandler innerRecognitionListener(RecognitionListener innerRecognitionListener)

Set inner recognition listener.

Parameters:

innerRecognitionListener - inner recognition listener

innerRecognitionListener

public RecognitionListener innerRecognitionListener()

Get inner recognition listener.

Returns:

inner recognition listener

onDataReceivedImpl

protected void onDataReceivedImpl(Float rmsdB,
                                  int layersCount,
                                  float[] dBmArray,
                                  float[] ampsArray)

Description copied from class: DbmHandler

Implement your own data conversion.

Specified by:

onDataReceivedImpl in class DbmHandler<Float>

Parameters:

rmsdB - any data

layersCount - layers count

dBmArray - array of normalized (in range [0..1]) dBm values that should be populated by you. Array size is equals to layersCount value.

ampsArray - array of amplitude values that should be populated by you. Array size is equals to layersCount value.

This values affect the appearance of bubbles. If new amplitude value is greater than previous value and normalized dBm value is greater than 0.25, bubbles will appear on screen. In case if amplitude is less than previous value, exponential smoothing (Holt - Winters) used for smoothing amplitude values.

release

public void release()

Description copied from class: DbmHandler

Called after AudioVisualization.release() ()} call.

Overrides:

release in class DbmHandler<Float>
