This is the Nigerian component of the International Corpus of English, a one million word corpus of written and spoken Nigerian English for linguistic research. It can be used as a stand-alone corpus or in conjunction with other components of the International Corpus of English (such as ICE-GB, ICE-India, etc.) to compare international varieties of English. The corpus consists of several parts: the written part is avilable as text files, xml files and xml files with parts of speech tagging. For the spoken part, the eaf files (ELAN files in xml format) together with the text files are available. The corresponding sound files can be downloaded in a separate file. In addition, we provide the corpus manual as well as a spreadsheet with metadata (speaker age, gender, ethnic group and profession) and XML specifications.
