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
