face recognition (ESP-WHO) with vocal feedback (A2DP)

[myrnaleo]

I want to do a facial recognition project with the ESP EYE board, using the ESP-IDF development environment as well as the ESP-WHO library. My goal is to create a system that can detect faces and provide voice feedback through an audio kit, connected via Bluetooth using A2DP source.
So my question is how to use the Esp IDF A2DP-source example in my ESP-WHO code to send the voice message over Bluetooth when a face is recognized??????
Any help please !!!
