CMU Sphinx under Ubuntu/Linux

CMU Sphinx is a set of tools for automatic speech recognition. Here's an example of how to install it and a simple C program with comments.

More information can be found here:

Gstreamer

This example requires Gstreamer. Prior to installation, you will have to download and install it.

$ sudo apt-get install gstreamer0.10-plugins-base

Installation

*) Download the latest sources of sphinx base and pocket sphinx (currently, version 0.7):
http://sourceforge.net/projects/cmusphinx/files/sphinxbase/
http://sourceforge.net/projects/cmusphinx/files/pocketsphinx
*) unpack and install
$ tar xvf sphinxbase-0.7.tar.gz
$ cd sphinxbase-0.7
$ ./configure
$ make
$ sudo make install
$ tar xvf pocketsphinx-0.7.tar.gz
$ cd pocketsphinx-0.7/
$ ./configure
$ make
$ sudo make install

*) Make sure you have paths configured correctly in your ~/.bashrc file:
export LD_LIBRARY_PATH=/usr/local/lib
export PATH=$PATH:/usr/local/lib:/usr/local
Test your installation

Download a simple program and type
$ ./run.sh
to compile and run.
It will simply recognize a few words and display them (like "hello world", "who are you".
