Speech samples were obtained from one hundred and four college students and rated for loudness and tempo. Four voice profile types were identified: loud-fast, loud-slow, soft-fast, and soft-slow. A distinctive personality profile is said to correlate strongly with each voice profile type. There were very few personality traits, however, that would not be easily discerned in forms of behavior other than voice type in the rather sketchy personality profiles elicited (using the Minnesota Multiphasic Personality Inventory).
