Wake Word "heard" chime/tone/Audio file on ESP32-S3-Box-3?

Running a custom microwake word on a fleet of S3 boxes around our house. A few of the devices can be hard to physically look at depending on where you are in the room/house - and while we have pretty decent wake word detection it’s obviously never perfect. It would be amazing to be able to play a sound, preferably a file so it could be customized but I’d take a beep at this point so we know it’s “safe” to issue the command.

I’ve seen that with the Voice PE this is actually an optional flag you can enable in the YAML like so:

wake_word_triggered_sound_file: https://someaddress.com/yes.flac

but trying that same syntax it’s doesn’t seem supported on the ESP32-S3-Box-3.

Anyone have thoughts or ways that can be done today?

ESPHome does not yet support having the box-3 listen and play at the same time (I2S duplex). There are plans to improve this, but they’ve been put on hold — we’ll have to wait.ESPHome Project Board · GitHub

Ah, thanks for that - a shame it’s on hold but glad to know it’s in the pipeline somewhere (no pun intended!)
