Why has it taken so long to get good voice control? This was the big question at the CES talk "The next big thing: Is the keyboard dead?"
A few responses came up:
• It takes natural language understanding
• Being able to interrupt while the computer is still talking and have it understand was an advancement in of itself (but we have been averaging 20% reduction in error rates for the past decade and that's not slowing down any)
• Disambiguating who is speaking by using gaze and body language will be important as the number of listening devices increases
Do you use voice commands with your devices regularly? Would you say your own keyboard is near extinction?
