Sphinxtrain

This is SphinxTrain, Carnegie Mellon University's open source acoustic model trainer. This directory contains the scripts and instructions necessary for building models for the CMU Sphinx Recognizer.

This distribution is free software, see LICENSE for licence.

For up-to-date information, please see the web site at

http://cmusphinx.sourceforge.net

Among the interesting resources there, you will find a link to "Resources to build a recognition system", with pointers to a dictionary, audio data, acoustic model etc.

For introduction in training the acoustic model see the tutorial

Installation Guide:

This sections contain installation guide for various platforms.

All Platforms:

You will need Perl to use the scripts provided. Linux usually comes with some version of Perl. If you do not have Perl installed, please check:

http://www.perl.org

where you can download it for free. For Windows, a popular version, ActivePerl, is available from ActiveState at:

http://www.activestate.com/Products/ActivePerl/

For some advanced techniques (which are not enabled by default) you will need Python with NumPy and SciPy. Python can be obtained from:

http://www.python.org/download/

Packages for NumPy and SciPy can be obtained from:

http://scipy.org/Download

Linux/Unix Installation:

This distribution now uses GNU autoconf to find out basic information about your system, and should compile on most Unix and Unix-like systems, and certainly on Linux. To build, simply run

./configure
make
make install

This should configure everything automatically. The code has been tested with gcc.

Also, check the section title "All Platforms" above.

Note for installation from the GitHub source code, you will additionally require autoconf, automake, libtool, and autoconf-archive, which you can install on Debian/Ubuntu for instance like this:

sudo apt install autoconf automake libtool autoconf-archive

Likely this will be switched to CMake in the very near future.

Windows Installation:

To compile the SphinxTrain under MS Visual Studio 2010 (or newer - we test with Visual C++ 2010 Express):

1. load SphinxTrain.sln located in SphinxTrain directory
2. compile all the projects in SphinxTrain (from SphinxTrain.sln)

MS Visual Studio will build the executables under .\bin\Release or .\bin\Debug (depending on the version you choose on MS Visual Studio), and the libraries under .\lib\Release or .\lib\Build.

If you are using cygwin, the installation procedure is very similar to the Unix installation.

Also, check the section title "All Platforms" above.

Acknowldegments

The development of this code has included support at different times by various United States Government agencies, under different programs, including the Defence Advanced Projects Agency (DARPA) and the National Science Foundation (NSF). We are grateful for their support.

This work was built over a large number of years at CMU by most of the people in the Sphinx Group. Some code goes back to 1986. The most recent work in tidying this up for release includes the following, listed alphabetically (at least these are the people who are most likely able to help you).
