I’ve been trying to get the voicerss method to work. I have OpenHAB running on a raspberry pi with a Bluetooth USB adapter. The BT adapter is paired with my stereo system. If I run a YouTube video on my RPI the sound is played over my speakers. But I can’t seem to get OpenHAB “say” commands to play over my speakers. I can see in my log that the command was issued. Any help would be appreciated. Is the Bluetooth binding necessary for this to work?
Bluetooth binding is not a prerequisite to get the tts working, did you try to put the url of voicerss with your key in a browser and got the voice file?
Just to update this thread, the thread below shows how to get Google TTS working.
