Follow-up to cube root trick

Following up on the cube root trick post, I wrote a version that speaks the number in Chrome. It’s an experimental API and I doubt I’m choosing the voice very well. But it does train how to do the trick better than reading the cubed number on screen.

On browsers that don’t support this API it degrades down to the way the previous version worked.

I also updated the old tool to take input once the second number is typed in - with that I got down to a sustained 3.5 second response time.
