In the mid-sixties, however, with her stage career dimming, she began to conduct vocal coaching classes designed to aid women in how they verbally presented themselves. The six-class course was first called Speech Cosmetics, and then — as it became more popular and increased in scope — Speech Dynamics. Ms. Sarnoff went on to coach businessmen, corporate heads and politicians such as Jimmy Carter, Menachem Begin, Bob Dole and Warren Christopher. Her ethos was that everyone could become a relaxed and commanding speaker if they could only isolate and accentuate their strengths and dispel their weaknesses. She instructed her clients to project "the vibe of joy," "the vibe of concern" and "the vibe of authority" when speaking in public. One of her maxims was "Make sure you have finished speaking before your audience has finished listening."
