homeService: Voice-enabled assistive technology in the home using cloud-based automatic speech recognition
Heidi Christensen, Iñigo Casanueva, Stuart P. Cunningham, Phil Green, Thomas Hain · 2013
We report on the development of a system which will bring personalised state-of-the-art automatic speech recognition into the homes of people who require voice-controlled assistive technology. The ASR will be sited remotely (‘in-the-cloud’) and run over a broadband link. This will enable us to adapt the system to the user’s requirements and improv the accuracy and range of the system while it is in use. We outline a methodology for this: the ‘Virtuous Circle’. A case study indicates that we can obtain acceptable performance by adapting speakerindependent recognisers with 10 examples of each word in a 30word command-and-control vocabulary. We explain the idea of a PAL- a Personal Adaptive Listener- which we intend to develop out of this study.
