As Smart Home enthusiast i want to control my home by voice without the cloud.
There are solutions like rhasspy (https://rhasspy.readthedocs.io/en/latest/) for this.
But there is no out of the box Hardware like Sonos Speakers which can be used for input.
To not reinventing the wheel for every solution of this kind a streaming server as option for voice assistants would be very helpfull. So each third party service can hookup this stream and do its thing with the audio.
