Subject: Add a simple text-to-speech challenge type.
X-Git-Url: https://git.cworth.org/git?p=mnemon;a=commitdiff_plain;h=3c887fd06a0a6790db978d13df4cc73f6d5b75b0

Add a simple text-to-speech challenge type.

This is implemented by doing the following:

     echo $challenge | festival --tts

But we actually make that invocation in a little script named mnemon-tts
because I'm too lazy to code up a custom invocation for this challenge
type.
