This book serves as a guide for the native and non-native speaker of English in overcoming various problems in articulation, rhythm, and intonation. It is also useful in group therapy speech programs. Forty-five practice chapters offer drill materials for all the vowels, diphthongs, and consonants of American English plus English stress and intonation. Examples of common spellings for each sound are included for non-native speakers of English. A number of ear-training exercises and aural discrimination tests are offered to assist aural recognition and provide information regarding probable errors. Suggestions and examples are provided for persons who cannot produce the isolated sound or who have difficulty with simple use of stress or intonation. The volume consists of 49 chapters, beginning with a series of background chapters, and is divided into four parts: "An Introduction to Speech Improvement,""The Pronunciation of the Consonant Targets of American English,""The Pronunciation of the Vowel and Dipthong Targets of American English," and "The Use of Stress and Intonation." Included in the appendix are an articulation test and two copies of an evaluation form to facilitate the diagnosis of students' problems. (RB)
