I checked with a friend about the possibility of lock in and of high switching costs in speech recognition game. In his opinion is pretty similar: -- [snip] I suspect there's a non-trivial cost in switching between vendors. a. A lot of "training" is needed to generate models (HMMs, hidden markov models) that work well. Lots & lots of data collection/annotation and CPU cycles. In fact, they frequently have to upgrade their models when they turn on the service in a different geographical part of the US. b. The application-level SW libs. I recall Nuance had some pretty nifty libs that make it easy to handle natural language queries (in a well-defined domain). Not sure if the competition has caught up. c. Large companies also do a TON of testing before they turn on a service, esp if they are used for stock trading etc. (Big difference for us who are used to turning something live in < 24hrs!) So I suspect the "bakeoff" occurs before they select a vendor, and are not likely to change. Don't forget that voice recog tech in the GE Advantium oven!!! -- Regards -Dinesh
