Voice recognition works particularly well when the computer knows what you are trying to say, and just needs to track along with you.
Which leads to an idea for a plug-in for commenters – not for this web-site, but for some others that I frequent.
Before leaving a comment, the system will require you to turn on a microphone, and read some text out aloud, while the voice recognition system tracks along with you to the end.
What text will you need to orate? The complete article you are about to comment upon.
That way it will be impossible to add comments without having actually read the passage you are commenting on.
The Internet need not thank me personally for this idea; the improved quality of comments will be thanks enough.
