This paper describes an application of speech rate conversion technology to video editing. In video editing, it is common to search through the material at several times normal speed. The speech rate conversion technology maintains the original pitch and timbre of speech despite playing it back at a faster rate, which is varied adaptively to permit fast listening in real-time. In listening tests, users were able to comprehend speech played at up to 5 times normal speed which was incomprehensible without the adaptive rate conversion.
