This was done to see whether there is a covert contrast between the participants’ correctly and incorrectly pronounced bilabial plosives. A pairwise t-test showed that there is a covert contrast between what English children intended as [pᑋ] and what they intended as [b], although these two forms were both transcribed by adults as [b]. Similarly, a pairwise t-test showed that there is a covert contrast between what Dutch children intended as [ ̬b] and what they intended as [p], although these two forms were both transcribed by adults as [p]. It was also found that while English and Dutch participants both reverted to a short-lag labial plosive, the VOT values of these short-lag plosives did not overlap between the languages.Show less
