"The book provides useful insights into phonetic and phonological perspectives of language research, including the basics of data collection, methods of recording, and selecting equipment. [...] The collection is a valuable tool of individual resources for anyone interested in an in-depth study of various phonetic and phonological theories, along with their assumptions and interpretation. The exhaustive treatment of the underlying forms of features with special reference to certain African languages, both in terms of tones and features, makes the book an important contribution to the field of phonology."Seetha Jayaraman in: Linguist List 23.2378
