We test both bottom-up and top-down ap- proaches in learning the phonemic status of the sounds of English and Japanese. We used large corpora of spontaneous speech to provide the learner with an input that models both the linguistic properties and statistical regularities of each language. We found both approaches to help dis- criminate between allophonic and phone- mic contrasts with a high degree of accu- racy, although top-down cues proved to be effective only on an interesting subset of the data.
