What's Wrong?

I've been using speech with the /voice option today, and now it has stopped "hearing" me. I press the space bar; the cursor moves as I speak, but no text appears. When I'm done and release the space bar, the message on the right side of the screen reports that no speech was heard.

What Should Happen?

My voice should be transcribed as earlier today.
