Try HTK HMM toolkit or Sphinx speech recognizer.
There are some acoustic models and language model for Sphinx in American
English.
It is not so robust, but works.

Subject: [speech-recognition] Need advices on speech recognition project
Hello, I am an undergraduate student looking to do a senior project on
speech recognition. The object of my project is to used speech recognition
system to control a device. My partner is working on designing this particular
device and my part on this project is the speech recognition. So far on my
research, I learned that speech recognition is related to dsp. It uses
algorithms to recognized/analysis a speech input and produces a desired output
that say it recognized this speech pattern.
What I need advices on is how to go about doing my part. So far from my
research, an algorithm called "Hidden Markov Model" is the most efficient way to
analysis a speech input. I'm thinking of getting a dsp board to program
this algorithm and produce an output in binary code that would go into a
microcontroller board that will control a device. What I don't know is how
overwhelming programming this algorithm would be. I have experience with basic
computer programming and very little C#. I read a dsp overview book before and
my partner do have experience in C++. I do know the block diagram for hidden
markov model, but do not fully understand it.
My desired output is somehow getting the dsp board to recognized a speech
pattern and produce a binary code that represent this pattern so that I can use
it to control something. I have 6 months to do this. Is this something doable in
6 months or will programming this algorithms be too much for me and I should
focus more on getting some sort of a speech recognition chip and say stick it on
a dps board and focus on getting the dsp board to produce the binary code
output? Or is there a better way about going at this. If you have any advices,
suggestions, or even experience with something like this that can help me out I
would really appreciate it.
