Thanks for reporting the issue. Six days ago the microphone volume indicator feature was released. The issue you're having might be related with that.
Let me bring some insights about the microphone status before jump to possible ways to fix the problem.
- Spinning arrows: It means that the app is trying to connect with the speech recognition service, watch a second every 5 minutes it's the expected.
- Mic icon with line through: It means that the app is not recording and is waiting for you to press the Ctrl key to start listening.
- Mic icon fading it and out: It means that is recording and showing you the sound volume level.
Press Ctrl before say every command mode example
Continuous Recognition mode example
I just sent a new version of the extension with small fixes that could fix the reported issue.
In case you continue seeing the problem I'd recommend you open the extension admin page and switch between modes (Press Ctrl before say every command | Continuous Recognition). It might fix it.
In case the problem persist try to uninstall the extension and install it again from the chrome store or the website. Remember choose the right speech recognition mode before start playing with it.
The spinning arrows icon might telling us that you have some kind of network problem. I'd recommend you as part of all these tests, play with the app using another wifi network. And just in case, please check if your antivirus has some web service turned on. For example I know that avast blocks some ports that could affect the speech recognition online service.
Let me know if the app got fixed!
