P-base is a database of several thousand sound patterns in 500+ languages, which I used in my dissertation to argue for emergent feature theory, which is intended to account for the prevalence of phonetically natural classes, something which universal distinctive features have also been used to account for.

A new version of P-base is available (November 29, 2007).

P-base 1.92 for Windows (also runs in Linux under Wine)

P-base 1.93 for Linux

Mac version coming soon?

To run the program, unzip/extract and click on "pbase1.92.exe" in the pbase1.92 folder (Windows) or type "./pbase1.93" (Linux).

Updates:

1 December 2007: version 1.93 for Linux: fonts don't look as nice as in the Windows version.

29 November 2007: New in version 1.92: languages load faster, negative searches are allowed, inventories and feature analyses can be copied and pasted, feature economy can be calculated for inventories, new "add new language" feature added. Complicated searches involving sound patterns are still a little flaky, but searching inventories works well.

11 November 2007: fixed problem that caused languages starting with the letter A to appear twice in the menu.
