Abstract

Recent advances in technology have led to the availability of powerful speech recognizers at low cost and to the possibility of using speech interaction in a variety of new and exciting practical applications. The purpose of this research was to investigate and develop the use of speech recognition in live television subtitling. This paper describes how the “SpeakTitle” project met the challenges of real time speech recognition and live subtitling through the development of a customisable speaker interface and use of „Topics‟ for specific subject domains. In the prototype system (described in Hewitt et. al. 2000 and Bateman et. al. 2001) output from the speech recognition system (the IBM ViaVoice ® engine) is passed in to a custom-built editor from where it can be corrected and passed on to an existing subtitling system. The system was developed to the extent that it was acceptable for the production of subtitles for live television broadcasts and it has been adopted by three subtitle production facilities in the UK. The evolution of the product and the experiences of users in developing the system in a live subtitling environment are considered, and the system is analysed against industry standards. Ease-of-use and accuracy are also discussed and further research areas are identified.
