 Further analysis showed that dominant Italian bilinguals had detectable foreign accents when speaking English, but early bilinguals (English dominant) had no accents in either language.This suggests that, though interlingual interference effects are not inevitable, their emergence, and bilingual dominance, may be related to a CP.These difficulties are attributed to a phase around age eight months where bilingual infants are insensitive to vowel contrasts, despite the language they hear most.
