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.
