I love your app so much.
I found that when I say "Tower", the engine recognizes it as "," for some reason.
So I added "," to voice keys and the engine then recognizes "Tower" perfectly but on saving the profile or toggling voice recognition, the app shows "phrase cant be an empty string" error.
The app is still usable since I just need to add the voice key manually every time but I will be very grateful if you can fix it.
