Low Back Vowel Query

[Terry Irons]

Across much of the south, the back vowel in words such as hawk has a
strong back upglide.  In fact, in some cases, it is the upglide that
distinguishes words such as cod and cawed, which show a near merger in
the speech of some. But in analyzing the speech of some people in
Kentucky, I have noticed a curious pattern, which is the basis of this
query.

Again and again, I have observed the lose of the back upglide before
voiceless alveolar stops.  For example, cawed and  talk both have an
upglide, but words such as bought and taught do not.  They are
monophthongal.  I am wondering if anyone else has observed or commented
on such a conditioned loss of this glide, and whether this process may
be a factor in the back vowel merger.  If so, it might such that the
merger is merger by approximation in some places, rather than merger by
expansion as has been argued by others (e.g. Herold)
