Carefully selected and organized speech material
The lessons are arranged in four groups, each emphasizing different aspects of auditory-visual speech understanding: (a) Vowels, (b) Consonants, (c) Stress, Intonation and Length, and (d) Everyday Communication. The lessons offer more than 1,200 speech utterances, with a set of 6 to 12 in each lesson.
