A speech system has a speech input channel including a speech recognizer, and a speech output channel including a text-to-speech converter. Associated with the input channel is a barge-in control for setting barge-in behavior parameters determining how the apparatus handles barge-in by a user during speech output by the apparatus. In order to make the barge-in control more responsive to the actual speech output from the output channel, a barge-in prediction arrangement is provided that is responsive to feature values produced during the operation of the text-to-speech converter to produce indications as to the most likely barge-in points. The barge-in control is responsive to these indications to adjust at least one of the barge-in behavior parameters for periods corresponding to the most likely barge-in points.

Abstract For small, portable devices, speech input has the advantages of low-cost and small hardware, can be used on the move or whilst the eyes & hands are busy, and is natural and quick. Rather than rely on imperfect speech recognition we propose that information entered as speech is kept as speech and suitable tools are provided to allow quick and easy access to the speech-as-data records. This paper summarises our work on the technologies needed for these tools – for organising, browsing, searching and compressing the stored speech. These technologies go a long way towards giving stored speech the characteristics of text without the associated input problems.
