Task interference with a discrete word recognizer
Speaker dependent, discrete word recognition is the simplest and most successful form of automatic speech recognition. In the near future, it is likely that this technique will be the basis for a variety of commercial speech interfaces. However, discrete word recognition requires users to insert relatively long pauses between each word of an utterance. This paper describes an experiment that was performed to determine whether this unusual way of speaking will interfere with the performance of complex tasks.
