Sphinx II – Speech Recognition on Ubuntu Linux

I just set up CMU Sphinx II on Ubuntu. I just want to test how this Linux Speech Recognition work. I installed the following packages: libsphinx2g0, libsphinx2-dev, sphinx2-bin and sphinx2-hmm-6k. The resource file will be in /usr/share/sphinx2/model/ which contains hmm (Hidden Markov model based-file) and model (Language Model related files). I just type

sphinx2-demo

to test it. It works but not perfectly accuracy output. I think it is needed to be trained. However, It’s a nice Speech Recognition system for Linux.

  1. Did you tried it on Asterisk? well, if you are talking about Sphinx with Asterisk PBX, then I’ve never luck to integrate Sphinx 3 and 4 with Asterisk. However I tried Sphinx2 with Asterisk and it worked well for me on Asterisk 1.2.x, I followed the following steps:

    If version 3 and 4 works for anyone please share. Thanks

  2. Thanks for good suggestion Sunny. I’ll try to test it soon.

  3. I’m not sure if this blog is still updated or the comments are checked regularly, but could you explain, after having installed the necessary packages how you set it up to test it? Did you run that command in the terminal and simply talk into a microphone and it transcribed it somewhere for you? How could I setup a simple demonstration in say… a Debian-based distribution where I simply recite words and they are written in a text-editor. Any advice would be greatly appreciated.
