Vocal characteristics

“Analysis of vocal characteristics, also called paralinguistic data (Draisma & Dijkstra, 2004), like behavior codes, examines audio recordings of interviews to identify notable traits of the interviewer’s voice itself, rather than behaviors during the interview. These vocal properties include pitch (higher or lower sounding voices), intonation (rising or falling pitch), speech rate, and loudness” (Olson & Parkhurst, 2013).
