This is, as they say, "on behalf of colleagues not on the net" at
Cambridge University Linguistics Department.  They are working on
speech, especially with reference to accent, in relation to speech
synthesis/recognition, and publishing working papers with
phonetic/phonemic material included.  At present they have to put those
bits in by hand.  It seems to me that TeX could do a good job of
typesetting such material, IFF someone has made some suitable fonts.
We don't have Metafont working here, and anyway I don't know enough about
phonetic script to be able to design fonts for it.

Has anyone produced such fonts?
