 One of the good things about Sphinx is that it comes with precompiled binaries for Ubuntu and derivatives. Additionally, it has many language models , so you can use it for many human languages.

CMU Sphinx toolkit has a number of packages for different tasks and applications. It’s sometimes confusing what to choose. To cleanup, here is the list

• Pocketsphinx — recognizer library written in C.
• Sphinxbase — support library required by Pocketsphinx
• Sphinx4 — adjustable, modifiable recognizer written in Java
• CMUclmtk — language model tools
• Sphinxtrain — acoustic model training tools

You can download CMU Sphinx Toolkit from sourceforge

For installation of Sphinx 4 check the installation instructions in the wiki page.

- For Ubuntu and LinuxMint:

There is a PPA available for CMU Sphinx, but seems that is  not updated to work in Ubuntu 10.10 maverick Meerkat, at least for me didn`t work.The PPA is the following
