These are typically dealt with by either extending the phone set or mapping each phone to a matrix language counterpart. We use acoustic log likelihoods to assist us in identifying the optimal mapping strategy at a context-dependent level (that is, at triphone, rather than monophone level) and obtain new insights in the way English/Sepedi code-switched vowels are produced.enCode-switched speechLanguage mixturesEnglish/Sepedi code-switched speechConference PresentationModipa, T., Davel, M., & De Wet, F.
