This paper is an attempt to do a contrastive study of some aspects of the supra-segmental features of Igala and English phonology. It provides an opportunity to analyse the errors in the speech of Igala second language (L2) speakers of English. The framework used in the analysis is the autosegmental theory. Autosegmental theory lays claim to non-linear representation of sounds. Autosegmental phonology is adopted for its theoretical elegance and empirical relevance. A tiered approach to the study gives one an opportunity to analyse the speech errors in terms that are easy to appreciate; especially since the processes are characterized in such a way as to reflect the realities of phonological structure and organisation. Interviews and participant observation were used to obtain data. These were later supplemented by listening comprehension tests.
