Voice pitch data collected by Winter and Grawunder (2012). In an experiment, subjects participated in role-playing dialog under various conditions, while researchers monitored voice pitch (Hz). The conditions spanned different scenarios (eg: making an appointment, asking for a favor) and different attitudes to use in the scenario (polite or informal).
