9.2.2 Distribution of aspirated stops

Aspiration affects syllable-initial GA /p,t,k/ in strong syllables, unless /s/ precedes. This accounts for the presence of aspiration and approximant devoicing in the words below.  Aspiration (only) is present in the first two words; there is both aspiration and approximant devoicing in the second four.

 

Aspiration

peel – /piːl/

recall – /riˈkɑːl/

Other examples

return

ten

posses

call

caress

appeal

 

Aspiration and Approximant Devoicing

pure – /pjʊr/

twin – /twɪn/

betray – /biˈtreɪ/

acute – /əˈkjuːt/

Other examples

queen

repute

predict

tremendous

cravat

 

The words below have no aspiration and/or approximant devoicing. Note in particular the lack of aspiration in words like spaghetti, stability, skill, etc., and the lack of approximant devoicing in display, distract, obscure, where /s/ precedes the stop in the onset.

Lack of aspiration

spaghetti – /spəˈgɛt̬i/

stability – /stəˈbɪlət̬i/

skill – /skɪl/

Other examples

spin

stern

aspire

restore

discuss

musketeer

 

Lack of both aspiration and approximant devoicing

display – /dɪˈspleɪ/

distract – /dɪˈstrækt/

obscure – /əbˈskjʊr/

Other examples

spray

string

screen

splenetic

strategic

sclerosis

 

Ambisyllabic GA /p,t,k/ are not aspirated. While aspiration is always present in couponlatexacorn, it is absent in openlateracre (except in a very formal style of pronunciation). The /p/ in open, for instance, is subject to WSP and as a result is ambisyllabic, and therefore fails to be aspirated. By contrast, the /t/ in latex, which is followed by a strong vowel, is not affected by WSP, and is aspirated. Further examples are found below. Thus, [k] in reckon is similar to AN [k] in rekken, and [p] in happy is similar to AN /p/ in Appie.

Aspiration occurs in

biped – /ˈbaɪpɛd/

latex – /ˈleɪtɛks/

viscount – /ˈvaɪkaʊnt/

Other examples

Ampere

suntax

encore

 

No aspiration (because of WSP) in

bumpy – /ˈbʌmpi/

after – /ˈæftər/

anchor – /ˈæŋkər/

Other examples

open

atom

reckon

 

It should be noted that for most speakers, approximant devoicing (as opposed to aspiration proper) does apply after ambisyllabic /p,t,k/. In words like Aprilliquidaccuratemicrophone, where /p,k/ are ambisyllabic because of WSP, (/(eɪ(p)rəl)/, etc.), approximant devoicing devoices /r,w,j/ and /r/, respectively.

April – /ˈeɪprəl/

liquid – /ˈlɪkwɪd/

 

For all speakers it is the case that /r/ is devoiced after /t/, not just in words like nitrateinquestmicrobe, where /t/ is unisyllabic in the onset of a strong syllable (/(ˈnaɪ)(treɪt)/, etc.), but also in words like countrycontraentry, where /t/ is ambisyllabic.

nitrate – /ˈnaɪtreɪt/

inquest – /ˈɪŋkwɛst/

 

Advice for Dutch speakers
Try to pronounce a brief voiceless [h] as you release the closure for /p,t,k/ in words like payteakey. If this fails to produce the right results, compare the articulation of Dutch /p,t,k/ in words like poptotkok. You will find that while the initial stops are unaspirated in Dutch, the final stops may be aspirated. If they are, try to pronounce the initial stop in GA paTomcalm like the final Dutch stops. Avoid overgeneralizing aspiration to non-aspirating contexts like those in spinsteelschool. Remember that aspiration is strongest in accented syllables and longer after /k/ and /t/ than after /p/.
