Hi,

When I tried to run the DialogDemo.java, the following exception happened.

Exception in thread "main" java.lang.IllegalStateException: javax.sound.sampled.LineUnavailableException: line with format PCM_SIGNED 16000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian not supported.

It seems 3 LiveSpeechRecognizer run at the same time.

If I commented out two recognizers, this demo can run correctly.

Does it mean, only single recognizer can run at one time? Right?

Thanks a lot!
