On my previous commit I wrote the following, "As of version 1.0.0 macchina uses
google-speech to support text-to-speech. I've disabled this feature, please let
me know if you think this should be on."

This was a mistake from my side, the feature was available but, disabled by
default in versions 1.0.0 to 1.1.5.
The relevant code is only compiled into the binary if, and only if, the feature
is enabled at compile time.
This feature and the code have been removed on version 1.1.6
