In this manual, the phonetic structure of the Azerbaijani language and its phonological systems have been (systematically) explained by focusing on comparative materials from a number of different languages. Thus, the author defends his theoretical position, as well as persues common principles, through the topics raised. Additionally, he demonstrates his thoughts and considerations, while basing his own investigations upon existing perceptions in literature. As such, this book is primarily intended for philologists. However, these materials can be used by teachers of language or literature, along with postgraduates, dissertants, and students of philological faculties: including everyone interested in linguistics.
