Paul Moses

Paul J. Moses (1 April 1897 – 7 June 1965) was a clinical professor in charge of the Speech and Voice Section, Division of Otolaryngology at the Stanford University School of Medicine, San Francisco, where he conducted research into the psychology of the human voice, seeking to show how personality traits, neuroses, and symptoms of mental disorders are evident in the vocal tone or pitch range, prosody, and timbre of a voice, independent of the speech content.

Moses was influenced by both Sigmund Freud, Carl Jung, and notable preceding and contemporary researchers into the psychology of voice, including Sándor Ferenczi, Edward Sapir, Hadley Cantril, Gordon Allport, and Ross Stagner. Moses believed that the human voice was capable of expressing the contents of the psyche acoustically, comparing such a possibility with the way the founders of Psychoanalysis and Analytical Psychology suggested that dreams provide a visual expression.

Moses cited the work of singing teacher Alfred Wolfsohn, who taught his students extended vocal technique, by which some of them acquired vocal ranges in excess of five octaves, as a practical demonstration of the theories he developed at Stanford University School of Medicine, regarding the relationship between voice and personality.
