Speech recognition Look, no hands - speech systems provide a novel approach to surfing the Internet There are many situations where keyboards and monitor screens are not the most convenient input and output devices for computer systems. Speech recognition and voice output are now being talked about as a built-in option for the next generation of PCs, but a BT Laboratories development called Speak n Surf has already combined the two to demonstrate hands-free computing. In this application, pages downloaded from the World Wide Web are evaluated and the menu of links leading to other information is converted to speech on the fly to a vocabulary which can be used by the computer to recognise speech.(The high cost of previous systems is avoided because a pre-loaded vocabulary is not required.) Instead of clicking with a mouse, users identify their choice by calling it out. Having demonstrated the underlying technology works, the next step could be to use it in screenless teleshopping and for on-line information applications. Numbers for names A tough test for speech recognition systems is their ability to handle a wide range of regional and national accents. It is one which Brimstone, the name given to a testbed robot corporate enquiry system at BT Laboratories passes with flying colours. Brimstone is a fully interactive voice response system with the potential to provide name and number information for the 3,500 plus staff who work there. The systems is well passed the experimental stage and is undergoing full-scale user trials. Brimstone asks for a surname and how it is spelled; if there is any confusion or if a number of people share the same name, further information is requested. High recognition accuracy is essential since some people have names that sound very similar. There are many opportunities for practical applications using the system, for example, telephone banking, or travel enquiries and reservations.
