These experiments reflect work by Bruce Christensen during December 2006.

Note that the title of each experiment (e.g. vowel-pitch) has a 1:1 correspondence to a .def.xml file in the Language-ID/defs directory.

Using pitch (sampled at 100Hz) instead of F0

Using pitch sampled at 200Hz

This set of experiments is the same as the previous one, except that the pitch was sampled at 200 samples per second instead of 100 samples per second (committed as revision 195 in Subversion). Note that performance is worse in almost every case than when running the same experiments with 100Hz sampling. This seems to indicate that there is an error somewhere in the pipeline.
