Does anyone happen to know if there are significant companies in the speech-recognition space besides Dragon and Google?

One assumes that the NSA is doing a lot.

  Yes: http://en.wikipedia.org/wiki/Room_641A http://en.wikipedia.org/wiki/Room_641A I doubt they're inspecting all that traffic just to watch the pretty patterns.

  When I took a speech rec class last semester, we had a guy from BBN (subsidiary of Raytheon) give a talk about large-scale, extremely fast audio transcription. As in, systems that could process audio 30-40,000 times faster than real-time. They traded off recognition accuracy to get this, so their accuracy was around 50-60%, as I recall. I asked why something like that would be useful, and he said if you're looking at a lot of data (which I heard: eavesdropping on an entire telephone network) then all you need is a general idea of what people are saying and a few keywords before you can zoom in on specific clips for more thorough analysis. So yes, I'm sure NSA is interested.

    Yeah. People from Fort Meade are involved in a lot of NLP research, both in terms of primary research (writing their own systems) and funding research and open technology evaluations. Video surveillance systems are getting a lot of attention now too.

There's Microsoft. They purchased TellMe some time back and have had speech recognition in mobile Bing for some time now. I think it may predate Google (though not sure) with similar accuracy. http://www.microsoft.com/en-us/tellme/ http://www.microsoft.com/en-us/tellme/ In Vista, MS included speech recognition as part of the shipping OS: http://en.wikipedia.org/wiki/Windows_Speech_Recognition http://en.wikipedia.org/wiki/Windows_Speech_Recognition

  TellMe is also used in Windows Phone 7 and it works great.
