OpenHAB to speak like Amazon Echo


Does anyone know if Its possible (and documented) how to make the openhab on a RPI2 to speak commands like the amazon echo. Basic stuff like ‘okay’ and ‘motion detected’ etc…

I have searched online but suck on what search keywords to use.

TTS ? (Text to Speech)
OpenHAB ‘Say’ action?

The Ivona tts cloud service is free and owned by Amazon.
The quality of the voices are very good. The only better ones I have ever heard are the Loquendo - Nuance voices that don’t seem to be available for hobby use.

Has a nice write-up for Node-RED and Ivona.

An openHAB plugin for Ivona would be useful.
