Recently (in the past 1.5 weeks) the javascript library WebkitSpeechRecognition has refused to work properly. I've tested other electron applications that utilize the library (smart-mirror by evan cohen) and have run into issues with those.
It throws network errors under every circumstance I've tested it. The library seems to work fine in standard browser environments but I can't seem to get it to work with electron. Does anybody have any experience in wrestling with this?
It seems that Google has removed this feature for electron. See this discussion.
Configure your own Google Speech API credentials using https://console.developers.google.com and then set them on your system's environment variables. I had the same issue and got it working with this way. Make sure to restart your system after configuring the environment variables. Sometimes they don't get into affect immediately.
Please refer for more detailed steps: https://docs.smart-mirror.io/docs/howto/how_to_obtain_chromium_speech_keys.html
GOOGLE_API_KEY, GOOGLE_DEFAULT_CLIENT_ID, GOOGLE_DEFAULT_CLIENT_SECRET set their value to Key, ClientID and ClientSecret respectively.
