Docker missing espeak

So, I’m back. This time with a computer that has a actual GPU. And I got farther than before. (It’s much easier to get started now.)

I can get the docker server running, however it seems espeak is somehow missing from the container.

This is from the Tacotron2-iter-260K-824c091 branch and the 261000 checkpoint.

Ended up changing the Dockerfile so it installs espeak. Also made a pull request.
