How do you usually pronounce button
ən] or [bʌtn̩], as in my belly button is itching
. (No, I'm not going to discuss body hygiene). It's fine to use the former version with the schwa if you prefer a very clear and a more formal way of enunciation. In a normal, relaxed situation you will hear native speakers say [bʌtn̩] and you're invited to follow suit.
What happens here phonetically after you've dropped the schwa? The process is called
The consonants /t, d/ have the same place of articulation as /n/; they are all alveolar sounds (phoneticians call them homorganic consonants). Your tongue approaches the alveolar ridge to form a closure (= the approach
stage of a plosive) and the soft palate (= velum) is raised to shut off the nasal cavity. Then the closure is held for a few milliseconds (= the hold
stage), while the air that you exhale is blocked and compressed behind the closure. As the /n/ has the same place of articulation, all you have to do is to lower the velum, let the compressed air escape through the nasal cavity and make the vocal folds vibrate because the /n/ is a voiced sound, is it not? You can practise the nasal release in isolation by repeatedly saying /tn, tn, tn, tn, .../. What happens when you pinch your nostrils shut and try to say /tn/? You simply can't or can you? If you can still say /tn/, the air must be able to escape through some hitherto undetected crevice. Hmm ... where would that be?
But let's get serious again:
Nasal release (which some phoneticians call nasal plosion
) also occurs when there's no schwa to be dropped as in chestnut
or bet now
. It would, however, sound very peculiar to say [ʧesth
] rather than [ʧestnʌth
] and less relaxed to pronounce bet now
naʊ]. The same process of nasal release applies to the sequences /dn/, /pm/ and /bm/ as in sudden, bad news, topmost, lap memory, webmaster
or nab meat
, though - again - there's not always a schwa to be deleted first.The plosives /p, b/ are bilabial as is /m/, so that at the transition from the first to the second consonant it's just the velum which has to be lowered. And you can say the two consonants in isolation without any intervening aspiration: /dn, dn, dn, ..., pm, pm, pm, ..., bm, bm, bm, .../.
