This is amazing. As one of the commenters said it makes Alexa look completely outdated.
One curious question: I looked around your docs and git repo but couldnt find anything related.
When integrating with Twilio for telephony does it use Twilio's ASR or can it be confugired to use Whisper? One of the biggest hurdles in telephony is the SIP/SRTP gateway componet to use your own ASR - I presume you arent tackling that yet.
Again great demo and it can become a base library for most bots.
