Google Translate (TTS)
great to see the new Audio Notification API. I tested it but can't get it working with Google Translate. I think it's because you are sending not a proper Agent information when retrieving the data from Google Translate.
Here is the URL I tried:
Would be great if you could send some generic agent string like "Mozilla Agent..." to get it working. I assume that's the problem.
As long as the Notification API was not there, I had two more feature in place which were great and maybe you could implement them as well.
relative volume (+10 => increase current volume level by 10)
off after speak (power off the speaker after the notification)
Would be great if you could help me at least with the Google Translate, as that is a very important feature in home automation for the users. As long as that is not in place, I unfortunately can't use the new API.
