Zounds! An IPA Sound changer
Well, there’s more than one way to age a conlang!
And, now Jamie Norrish, the webmaster at artefact.org.nz, has that other way. As you three readers of this sad, little blog know, I have a handy, online Conlang Dialect Maker, which is based on a CPAN module that is based on the Zompist Sound Changer. Well, Mr. Norrish has created a whole different set of libraries for doing the same thing, only in Python! Unfortunately, I don’t know Python and don’t have the time to learn it right now, but if you do, the IPA Zounds application is for you.
Good luck!
