Directory Assistance Challenges
The Boston Globe has an article about the challenges that TellMe and Verizon have had with their automated directory assistance system. Many of the problems listed have more to do with the underlying speech recognition system then the actual application as doing such large scale grammars is still very leading edge technology. Anyway, it’s a decent read to get an idea of what sort of problems you may run into when deploying speech applications with extremely large grammars.
