Non-cloud wifi remote speaker/mic device - eviltoast

While I quite like the ability to broadcast TTS, media, and other such things to Google Nest or Amazon Alexa devices, I’m trying to rein in my HASS setup so that it doesn’t send data to our require cloud services.

Does anyone know of or recommend a wireless speaker service that can accept broadcast/streamed/sent audio without needing an internet connection. Bonus if it has a microphone that can integrate with something like a local Genie instance for accepting voice commands (without cloud processing)
