Alliteration Locator was built as a simple baseline for detecting alliterations. Although it bases it's decisions on orthographics rather than on pronunciation, it is very simple code.
Download source code at https://github.com/bean5/AlliterationLocator /zipball/master.
To download a compiled version, you can go to http://students.cs.byu.edu/~bean5/ling-utils/AlliterationLocator/dist/alliterationFinder.jar.
This is done by using Java.
