Ooh. Hold on. :D dispense has two pronunciations,Originally Posted by japanjapan
1. di'spense, with a [p]. :D
2. dis'spense, with a [p]. :D
The [p] sound has unreleased aspiration after [s]. That is, the puff of air we usually hear with [p], as in pet, is not fully released or not released at all. That [p] often sounds like a [b], especially to speakers whose first language does not have unaspirated sounds.
There's no [b] in dispense. :D
