Subject: Taps and flaps

In May I asked the List for suggestions about 'flaps' in
American English.
Thanks to the following people, who responded personally to
my query:

Sandra Bott, Karen S. Chung, John Coleman, Bruce Connell,
David Iannucci , Laura L. Koenig, Mark A. Mandel, Henry
Rogers, Larry Shriberg, David Stampe, Larry Trask.

A number of correspondents slapped my wrists for using the
term 'flap' to refer to the sound in American English in
words such as 'butter' and 'city', pointing out that most
authorities (Ladefoged, and Laduslaw and Pullum (!) being
the most often cited) carefully distinguish between 'flap'
and 'tap'. The American sound is a TAP.

What no one could offer, at least so far, is an operational
acoustic definition of a flap/tap such that I could distin-
guish a tap from a regular stop on a waveform or spec-
trogram. I am working on a possible methodology, but since
the relevant acoustic research has not yet been begun, I
will keep the speculation to myself until such time as I can
confirm my suspicions. It might, of course, be possible to
use the Microbeam facility, but I suspect that it's much
harder to do that and get reliable taps, since tapping is
partly a function of relaxed speech, and I really wonder how
relaxed the tip of the tongue can be with a pellet glued to
it...

The following is a half-baked bibliography that is the
result of all the responses. I have not yet had a chance to
dig them up, and in relevant cases fill in missing informa-
tion.
