All of the English voiced plosives, when
pronounced in a final syllable, pose a lot of
difficulty for Thai learners to master since, in Thai
phonology, there is no voiced plosive occurring
finally, and voiceless plosives: /p/, /t/, /k/, and
/?/, even though they can occur finally, they are
pronounced with no audible release (hence, short
VOT). In this case, it is suggested that when
learning pronouncing English voiced plosives, Thai
students try to vibrate their vocal cords to have
voiced feature in each phoneme1
