<br/><br/> This book is based on the modern view that the sounds of a language are significant only when they contrast with each other. It provides tests for finding out what the students's problems of learning the pronunciation of a foreign language are, and exercises to enable them to overcome their difficulties.  Each section concentrates attention on the difference in the pronunciation of a specific set of sounds.
