Invalid API Key with Google STT

[Chris Radomile]

I've got Jasper running on my RP3, and I would like to use the Google STT engine because in my testing, PocketSphinx had a lot of recognition problems and Wit.ai had a lot of latency issues, taking several seconds to realize that someone had spoken. I've followed the instructions and updated the profile.yml file with the API key and I've enabled the Speech API in my Google developer profile, but still no luck. I've tried formatting the API key in a couple different ways and even went so far as to input my API key directly in the source code, but still nothing.  Any ideas?

CRITICAL:client.stt:Request failed with http status 403
WARNING:client.stt:Status 403 is probably caused by an invalid Google API key.
