Prosody Tutorial: Lecture 14: Introduction to Features

This is Video 14 of our series on prosody, starting four lectures on prosodic features. To support both research and development, we need automatically-computable features for the various prosodic properties. Feature computation is typically done in three or four stages. Computed features never perfectly reflect perceptions, so observers and researchers need to use caution in interpreting them. 00:00 Features are Measurements 01:28 Low-Level, Mid-Level, and Meaningful Features 02:46 Technical Pitfalls 03:15 Computed Features at best Correlate with Perceptions 04:20 The Irreducible Subjectivity of Perceptions
