CMU Sphinx Python Modules

These are a number of modules that can be used to do speech processing, generally oriented towards CMU Sphinx file formats. In fact, there is a wide variety of stuff here, mostly things created during my (David Huggins-Daines) PhD work. You will find for instance pure-Python (but using numpy and scipy) implementations of certain feature extraction and adaptation algorithms, along with code to read and write the various files produced by SphinxTrain.

There is some code to convert things to FSTs and play with them, but it does not work, since the Python bindings for OpenFst have mutated greatly since it was written. In fact, it may have used my own personal wrapper library which may or may not still exist. Sorry.
