Interactive manipulation of replay speed while listening to speech recordings

Abstract

Today's interfaces for time-scaled audio replay have limitations especially regarding highly interactive tasks such as skimming and searching, which require quick temporary speed changes. Motivated by this shortcoming, we introduce a new interaction technique for speech skimming based on the so called rubber-band metaphor. We propose an "elastic" audio slider which is especially useful for temporary manipulation of replay speed and which integrates seamlessly into standard interface designs. The feasibility of this concept is proven by an initial user study.
