Can & Can't: differ in stress, vowel, length, (and b, d, g)
misa.j said:
Can you guys suggest me a good way to listen to and pronounce can and can't? I really have a problem with them.
For can't, my husband has suggested me to stretch my lips to the side and press my tongue behind my upper front teeth instead of actually pronouncing a 't' at the end.
For can, I should almost say it like "cun".
Are these good suggestions, or are there better ones?
Phonetic transcription may help.
can = /khae:n/ <== This is the isolated form in the dictionary, not universally applicable. In real life, 'can', as an auxiliary verb, becomes unstressed. An unstressed, non-i vowel tends to turn into the schwa sound /@/. ('Gun' has a vowel that is stressed, but otherwise identical vowel sound.)
"You
can watch TV after doing homework." -- /kh@n/
Here the 'can' is
unstressed & short schwa sound.
When the 'can' and 'not' are merged as 'cannot,' the schwa is retained. /kh@nna':t/. This is because an auxiliary verb is unstressed, whereas an adverb is stressed in consecutive speech. The only instance when 'can' and 'cannot' are pronounded /khae':n/ and /khae':nna't/ is when exphasis is given to the 'can' part to draw proper attention, e.g. when correcting a misunderstanding. In
ordianry (non-emphatic) speech, the
schwa must be used.
When 'cannot' is contracted to 'can't' something interesting happens; with the 'o' of the stressed adverb 'not' is being dropped, the stress associated with the 'o' becomes transferred to the 'a'. In a chain reaction, the stress revives the suppressed 'a' with the schwa sound back into the 'a' with the full /ae':/ sound. (One more phenomenon invoved is the occasional deletion of the /t/ in an 'nt' cluster. Not all the time, but quite often.)
can not > cannot > can't > can' (slang orthography)
/kh@n na':t/ > /kh@nna':t/ > /khae':nt/ > /khae':n/
Try saying the contracted from in answering the question;
Q: "
Can you come to the picnic ?"
A1: "I
can't." "Have a term paper to finish."
Make sure you have the 'can't' part either /khae':nt/ or /khae':n/; the point being
1) vowel position /ae/
2) vowel length long /ae:/
3) stress /ae':/ are all there.
Another quirk comes in when 'can't' is not the last word of a sentence. Especially when the consonant immediately following 'can't' is a /b/, /d/, or a /g/. When these sounds follow 'can't' the suppressed /t/ sound becomes reactivated to have the force of the glottal constriction, like the /h/ in the emphatic 'Ah' exclamation during a tennis match. These particular combinations will produce the
glottalized (intensified at the vocal cord) sounds /?b/, /?d/, and /?g/. Compare the following pairs and try to make an exaggerated distinction for practice.
"She can be really nice." /shi'
kh@m bi ri'

li nai's/
"She can't be the one !" /shi
khae':m ?bi th@ w@'n/
"You can do it !" /yu':
kh@n du': it/
"You can't do it !" /yu
khae':n ?du': it/
"I can go." /ai'
kh@ng gou'/
"I can't go." /ai
khae':ng ?gou'/
In these last three constructions, the intensified /?b/s, /?d/s, and /?g/s will give you another cue to the KAN sound meaning 'can't', not 'can.'
Summary: can vs. can't
can /kh@n/ is
unstressed, schwa, short.
can't /khae':n(?)/ is
stressed, ae, long.
When followed by b, d, g (rough notation: trial)
can+b,d,g -> k@mb, k@nd, c@ngg
can't_b,d,g -> cae':mp, cae':nt, cae':ngk
