[Feature Request] MQTT-microphone (Hermes protocol)

[vevsvevs]

What new integration would you wish to have? MQTT-microphone for ESP32.

If possible, provide a link to an existing library for the integration:

Please describe your use case for this integration and alternatives you've tried: In my opinion, HassOS is the best easy-deployment solution for HA-beginners and for home automation at all! But it also has many limitations related to used platform, especially in case of OVA-based images (which i personally use). The most disappointing thing is a lack of support of Bluetooth (device tracking) and audio (voice control) USB-dongles. BT issue was fully-solved with your amazing ESPHome component, but the audio problem still remains. There is a very promising project Rhasspy, which can take audio input data from MQTT payload (Hermes protocol) for later processing. IMO it would be amazing to get such integration in ESPHome!

I second this, especially with the esp32 audio kit.

So I am really interested in doing the development work for this over my Christmas break off work. There is a great example here.

I am thinking we allow for as much customization as we can for these devices. Base features:

• Configurable SiteID
• Trigger for Hermes connection
• Trigger for wake word detected/Listen detected
• Trigger for Listen ended
• Trigger for no matches detected
• Trigger for Audio playback started
• Trigger for Audio playback ended
