Hmm, tell me more, please. Fascinating— I was considering only written material.
I keep a computer history playlist on YouTube of all the computer videos I’ve made because of the historical significance of many. One video was made overnight when we could just show video running on a computer screen, even with bugs in the windows showing the videos, and the director wanted to demonstrate in a keynote address. I got pulled into a 6 hour lawyer’s deposition on another because of a Microsoft law suit over gesture recognition.

If they allow you to search the list on BBN, it should bring up a lot of voice recognition videos, mostly for battlefield logistics.
In actual fact, at the time of making the videos I had to do a lot of takes to show good recognition. I assume that 20 years on it should be doing a much better job.
