As noted on the Chromium Dev How-to [1] and on the
SpeechRecognition library docs [2], the Google TTS API
is really not the right API to call. While it's simple,
and allows you to authenticate via a simple token, it is
also limited to a max of *50* requests per day.
That's not a lot. I don't think many people will find that
useful, outside of quick testing (if they can even get an
API key - I couldn't figure out how to generate one that
worked correctly).
This commit introduces a new STT backend, google_cloud, so that
the Google STT backend can be deprecated eventually. To do so, we
needed to:
- Install the Google API Client Library
- Create a new STT class which knows how to turn a provided Google
JSON credentials file into a string (the SpeechRecognition library
expects you to pass in the JSON string, not a file path, nor an object).
Any person wishing to use this will need to:
- Enable the Cloud Speech API on the Google Cloud Platform console
- Create a new Service Account Key, and download the credentials to
a secure location
- Configure that location in mycroft.conf, like so:
"stt": {
"google_cloud": {
"credential" {
"json": { contents of downloaded credentials }
}
}
}
It's worth noting that the Cloud Speech API has a free quota of
60 minutes per month, which would probably stretch further than 50
individual requests. So for hobbyists, it should be nothing but
a net benefit.

This commit officially switches the mycroft-core repository from
GPLv3.0 licensing to Apache 2.0. All dependencies on GPL'ed code
have been removed and we have contacted all previous contributors
with still-existing code in the repository to agree to this change.
Going forward, all contributors will sign a Contributor License
Agreement (CLA) by visiting https://mycroft.ai/cla, then they will
be included in the Mycroft Project's overall Contributor list,
found at: https://github.com/MycroftAI/contributors. This cleanly
protects the project, the contributor and all who use the technology
to build upon.
Futher discussion can be found at this blog post:

This commit also removes all __author__="" from the code. These
lines are painful to maintain and the etiquette surrounding their
maintainence is unclear. Do you remove a name from the list if the
last line of code the wrote gets replaced? Etc. Now all
contributors are publicly acknowledged in the aforementioned repo,
and actual authorship is maintained by Github in a much more
effective and elegant way!
Finally, a few references to "Mycroft AI" were changed to the correct
legal entity name "Mycroft AI Inc."
==== Fixed Issues ====
#403 Update License.md and file headers to Apache 2.0
#400 Update LICENSE.md
==== Documentation Notes ====
Deprecated the ScheduledSkill and ScheduledCRUDSkill classes.
These capabilities have been superceded by the more flexible MycroftSkill
class methods schedule_event(), schedule_repeating_event(), update_event(),
and cancel_event().
