intrusive schwa

[Prof. Roly Sussex]

The Irish schwa between /l/ and /m/ is also well known in
Australia - we have a big Irish population. What is more
interesting, though, is a tendency for "thrown" to become
"throwen", similarly "blown" and other verb forms, but
apparently not "throne". Is this phenomenon known in the
US, and does anyone have any comments on it? In Australia
it's clearly non-standard, but it's creeping into use
in the media.
