Description: 
Sphinx-3 is CMU's state-of-the-art large vocabulary speech recognition system.
It uses Hidden Markov Models (HMM) with continuous output probability density
functions (PDF).  It supports several modes of operation.  The more accurate
mode, known as the "flat decoder", is descended from the original Sphinx-3
release.  The faster mode, known as the "tree decoder", was developed
separately.  The two decoders were merged in Sphinx 3.5, though the flat
decoder was not fully functional until Sphinx 3.7.

The previous paragraph is upstream's description.  I have named this packages
"cmusphinx3" instead of "sphinx3" because we already have an unrelated "sphinx"
package in Fedora, so "sphinx3" looks like a compatibility package.  Matters
are made more complex by the fact that upstream has "sphinx3" and "sphinx4"
projects (I will be submitting the latter soon) which serve the same purpose
and are both under active development, but sphinx3 is written in C and sphinx4
is written in Java.  Combine that with upstream's tendency to refer to sphinx3
version 0.7 as "Sphinx 3.7", as in the paragraph above, and things get a bit
confusing.

I have chosen to name the packages "cmusphinx3" and "cmusphinx4" to try to
avoid the confusion.
