This book sets out the sound systems of twelve Nigerian languages and English (both British and American) in order to give teachers a better understanding of why students who are speakers of these languages have difficulty in certain areas of English pronunciation. The Nigerian languages are: Efik, Etsako, Fula, Hausa, Ibgo, Ijo, Isoko, Itsekiri, Nupe, Tiv, Urhobo, and Yoruba. Each language description is arranged in the same way in order to enable the teacher to compare whichever language or language he is interested in with English as regards the features covered. Four aspects of each language are described: consonants, vowels, syllable structure, and tonal or intonation structure. Following this, an account is given of the major difficulties a student speaking that particular Nigerian language is likely to have in learning the English sound system. Finally, a list of publications about the language is given. Technical terminology is kept to a minimum, and a glossary is provided for those technical terms which are used. (FWB)
