Capture audio from Java ME application

[Ransika deSilva]

Dear All,
Can we capture the voice through a MIDP application. I mean say if the user says 'Hello' to the mouth piece, can we get it as an input to the MIDlet. Thanks a lot. Regards

Yes ... maybe you can capture using MMAPI 1.1 RecordControl and "capture://audio", but will depend on the particular device.
Check java.sun.com/products/mmapi

No ... there is no J2ME API for voice recognition as far as I know.

There is the Java Speech API but it�s not (nor has been ported) for J2ME

The code to capture audio using MMAPI 1.1 (MMAPI javadoc sample)

try {
    // Create a DataSource that captures live audio.
    Player p = Manager.createPlayer("capture://audio");
    p.realize();
    // Get the RecordControl, set the record location, and 
    // start the Player and record for 5 seconds.
    RecordControl rc = (RecordControl)p.getControl("RecordControl");
    rc.setRecordLocation("file:/tmp/audio.wav");
    rc.startRecord();
    p.start();
    Thread.currentThread().sleep(5000);
    p.stop();
    rc.stopRecord();
    rc.commit();
} catch (IOException ioe) {
} catch (MediaException me) {
} catch (InterruptedException e) { }
