    I'm trying to use the HUB4 acoustic model and language model with Sphinx4.1.0 Beta2.
    I'm receiving the following error message when allocating the recognizer:

      Most probably it's a typo somewhere. See this thread:

      https://sourceforge.net/forum/message.php?msg_id=7062951

      To help you more I need to get the complete test, not just the configuration file.
