I'm trying out a new program called Dragon Naturally Speaking. It appears to be a useful program since it doesn't seem difficult to use, and it seems to recognize my voice without difficulty.
I've been dictating this post so far. One of the reasons I wanted to use it was to keep my arm from becoming stressed. It's nice to have an alternative.
I'll be trying this for the next few days at work. If it works as expected, I'll be able to use it in the classroom. I expect that my students will be absolutely fascinated by it.
