When international students have asked about American pronunciations of
'can' and 'can't' -- complaining that they don't hear a -t -- I point out
that the vowel in 'can' lasts a little longer than the one in 'can't'.
They find that explanation useful. DMLance
Or you can refer them to Hans Marchand's "Remarks about English Negative
SEntences", American Studies 20 (1938): 198-204, who observes that post-
auxiliary negation tends to be signalled more by vowel quality, stress, and
rhythm than by the presence of a segmental element. In fact,Jespersen's "Nega-
tion in English" (1917, p. 11) also contains this remark:
If we contrast an extremely common pronunciation of the two opposite
statements "I can do it" and "I cannot [sic] do it", the negative
notion will be found to be expressed by nothing else but a slight
change of the vowel [ai kaen du: it | ai ka:n du: it].
Jespersen is describing a different dialect from mine, but the point is that
vowel quality and length and phrasal rhythm is more of a cue than the presence
of a [t]. Where the rhythmic distinction neutralizes is just when the modal is
contrastively stressed: he CAN come/he CAN'T come. (I discuss this on p. 458 of
my 1989 book _A Natural History of Negation_, where I note I've occasionally
heard the repair query "can-yes or can-T'?")
