Putting Linguistics into Speech Recognition Manny Rayner, Beth Ann Hockey, and Pierrette Bouillon High-performance spoken dialogue interfaces typically use a spoken command grammar, which defines what the user can say when talking to the system. For complex applications, implementation and maintenance of this grammar is a major task requiring specialised expertise in computational linguistics and software engineering. The resulting grammars are difficult to maintain, and do not port easily to new domains. Regulus is an Open Source toolkit for construction of spoken command grammars, which has been developed since 2001 by a consortium whose main partners have been NASA Ames, the University of Geneva, and Fluency Voice Technology. Grammar development with Regulus is carried out using example-based methods and reusable grammar resources, which reduces the level of expertise needed and makes the process more automated. The Regulus approach is effective for building command grammars even at initial stages of a project when there may be little or no domain data available. Regulus has been used to build command grammars for several major projects. Among these are NASA's Clarissa, which in 2005 became the first spoken dialogue system to be deployed in space, and MedSLT, an Open Source medical speech translator developed at Geneva University. This book presents a complete description of both the practical and theoretical aspects of Regulus, including several example applications which can be downloaded from the companion website.
