Written by a speech therapist and Metropolitan Opera language coach, this book does what its title indicates it will. It concerns itself with speech production--pitch, speed, ennunciation, volume, etc., and with the general personality quality of the individual's speech. There is a special section for the preservation of youthful feminine voices. Packed with exercises for adults and children, this is a helpful and common sensical text which will be particularly useful to parents and teachers of children with minor speech eccentricities.
