This book is directed at students studying the economic and social development of Russia and the Soviet Union, as well as the nature of Russian government and its impact on the Russian people in this period at AS/A-level. It forms part of the new Heinemann Advanced History series which has been written specifically to cover modules set by each of the three Awarding Bodies (OCR, Edexcel and AQA).

The importance of an individual's voice in everyday social interaction can scarcely be overestimated. It is an essential element in the listener's analysis of the speaker's physical, psychological and social characteristics. Differences in voice quality reflect different habitual adjustments, or settings, of the vocal apparatus. Individual consonant and vowel segments can be thought of as momentary actions superimposed on these settings and voice quality, as the characteristic sound of a speaker's voice, thus pervades and to a certain extent determines the phonetic character of these linguistic segments. This volume sets out a phonetic description of voice quality, which has largely been neglected in other studies. Dr Laver's integrative approach is a major advance in general phonetic theory and his standardisation of descriptive terminology for the voice will be welcomed by those working in the fields of speech therapy, speech pathology, social psychology and communications engineering, as well as by students and specialists in speech science, phonetics and phonology.

This major new textbook is designed for readers who wish to pursue the study of phonetics from an initial to an advanced stage. It moves from a discussion of general concepts to a total of eleven chapters on phonetic classification, and it includes discussion of other issues such as the relationship between phonetics and phonology. There are illustrations from over 500 of the world's languages. Principles of Phonetics will be required reading for all serious students of speech and language.
