I am attempting to setup and use Mycroft entirely offline. I started with setting up the Selene-Backend and have all software installed. I am at the step for creating the API service files, specifically the device API service file which shows an environment variable is required for Google_Stt API key. I will not be using Google_Stt as I have a running deepspeech server. So my question is do I need to define that Google_Stt API key or can I leave it blank, if I leave blank how do I tell Selene to use DeepSpeech instead of Google_Stt?
Thank you for you time,
David
