**Acknowledgements**

It is thanks to an incredible group of talented people that I wrote this paper. I got to know each of their voices during innumerable conference calls, and their sense of humor in many face2face meetings. First, I would like to thank the chairs, Jim Larson, Dan Burnett, and Debbie Dahl, and not forgetting Scott McGlashan, whom I first met in the early 1990s when he was a PhD student involved in the SUNDIAL project and then later as co-chair with Jim Larson of VBWG. He showed great talent in leading the project's development. His departure in February 2014 was a big loss. I am also indebted to all the people who played such an active role throughout the years. These standards would not have been possible without their efforts. As there are too many to thank individually, I thank them collectively.

The W3C became our home, and from there, I would first like to thank the team contacts who always helped us to understand the W3C's processes and also gave us some very good ideas. Thanks to Dave Raggett, Kazuyuki Ashimura, Max Froumentin, and Matt Womer. Second, thanks go to the other team leads who contributed to broadening the scope of our work, such as Philipp Hoschka, the W3C Domain leader for the Ubiquitous Web, Richard Ishida for Internationalization (I18N), Judy Brewer and Janine Sajka for the Web Accessibility Initiative, and many other great people we met during the W3C Technical Plenary meetings, of course including Tim Berners-Lee.

I also have to mention my second home, the VoiceXML Forum, especially Val Matula and Rob Marchand who sit with me on the Board and, especially, Katie Valenti, our invaluable Program Manager for the ISTO team. Thanks.

I am also very grateful to Debbie Dahl and Roberto Pieraccini who read this paper and contributed so many comments and ideas. Finally, I cannot overlook Simon Parr for his timely assistance.
