Controlled natural language in speech recognition based user interfaces

Abstract

In this paper we discuss how controlled natural language can be used in speech recognition based user interfaces. We have implemented a set of Estonian speech recognition grammars, a speech recognition server with support for grammar-based speech recognition, an Android app that mediates the communication between end-user Android apps and the speech recognition server, and an end-user Android app that lets the user execute various commands and queries via Estonian speech. The overall architecture is open and modular, offers high precision speech recognition, and greatly simplifies the building of mobile apps with a speech-based user interface. Although our system and resources were developed with the Estonian speaker in mind and currently target a small number of domains, our results are largely language and domain independent. © 2012 Springer-Verlag.
