Broadcast voice message

I don’t know if it’s already possible but I am looking for a way to send voice messages. Some kind of a card where you press the button and you can talk and once you done it sends the message to the speakers.

  1. I can achieve something very similar with cameras that supports 2-way audio. It actually works great for me but it is only available on LAN as WebRTC doesn’t work over internet.

  2. I can type a text and broadcast it to speakers but that’s not great either. I need to type and only in English and it’s not really my voice

I guess I am looking for something like Google home broadcast feature, or Apple intercom

Anyone knows if something like that exists?

Is this a feature request or a help request?
