ESP-VA-SDK for ESP32-S3 without DSP

[Fahadk7]

Hi
I came across a youtube video on Espressifs Channel demonstrating ESP32-S3 Speech Recognition Demo, using Alexa Voice Assistant directly with S3 and no external DSP (https://www.youtube.com/watch?v=jf6G5KKGvSo) and Offline Speech also(https://www.youtube.com/watch?v=ARkuaeEW1eM)

I was trying to include this feature in my esp32 project.
Can you share some references or source code examples on implementing this feature
I intend to purchase ESP-BOX with the intent to use it as hardware to test this voice feature
Please let me know how i can succesfully implement this feature.
