Getting LineUnavailableException using more than one LiveSpeechRecognizer (Sphinx 4-5 prealpha)

[Romain L]

I tried to run the dialog example into the lastest version of CMU Sphinx, but I get this error :

javax.sound.sampled.LineUnavailableException: line with format PCM_SIGNED 16000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian not supported.

It happens only when I use more than 3 instances of LiveSpeechRecognizer. In the example given with the last version, the LiveSpeechRecognizer is instanced 3 times :

    configuration.setGrammarName("dialog");
    LiveSpeechRecognizer jsgfRecognizer = LiveSpeechRecognizer(configuration);

    configuration.setGrammarName("digits.grxml");
    LiveSpeechRecognizer grxmlRecognizer = LiveSpeechRecognizer(configuration);

    configuration.setLanguageModelPath(LANGUAGE_MODEL);
    LiveSpeechRecognizer lmRecognizer = LiveSpeechRecognizer(configuration);

Sorry, microphone access can not be shared, you can not create multiple live recognizers at once.

I'm using sphinx4-5prealpha-src.zip, and I'm getting the same LineUnavailableException, and I noticed that edu.cmu.sphinx.demo.dialog uses three instances of LiveSpeechRecognizer. Was this demo not meant for 4-5prealpha? If so, where can I find example files that are meant to work with sphinx4-5prealpha?

Thanks!

It means that either your microphone is unavailable, or that the required sample rate is not acceptable. Take a look at sphinx4-core/src/main/java/edu/cmu/sphinx/frontend/util/Microphone.java for more information.

Great, I'll take a look. Thanks for your help, and thanks for replying so fast!

I'm really excited about Sphinx.
