Thanks for the info.

Sorry, but I didn't quite get the argument here. Are you saying the "wav buffer" is different from the raw audio stream (=another buffer)?

Thats pretty good! 🙂

Somehow I was expecting this conclusion ^^ ... its just so much fun to simply connect nodes in Node-RED, especially since I've started to build several nodes for SEPIA as well 😃  
The text-to-intent part is probably still something that could be integrated easily into SEPIA custom services via Node-RED, but thats a story for another time 😉

I'll try to read a bit more about voice2json and its interfaces. It would be really great to enable users to share their custom voice models between the systems.
