Vowel Lengthening from V + Voiced Consonant

Some time ago, we had some discussion on this list of an alleged phenomenon whereby English vowels were reputed to be lengthened by a following voiced consonant.
 
This appears to me, at this time, to be incorrect.
 
I am wondering if those who asserted it might be kind enough to cite references — if they can.
