Using CMU's Pocketsphinx with a small set of words

http://stackoverflow.com – I want to use CMU pocket sphinx for recognizing between a small set of words. I created a corpus for them and created the model files here - http://www.speech.cs.cmu.edu/tools/lmtool.html. Now when I run the pocketsphinx_continuous executable with this model on my 12 core Linux machine, it takes about 5 seconds to recognize each word. Is this library usually this slow or am I doing something wrong? the console output shows that it is still searching and evaluating a large number of words where as the size of my model is only 12 words. Is there any other lightweight and easy to use library (HowTos)
