This DIY ESP32-S3 AI voice assistant wakes up on command, understands what you say, responds with speech, and can control LEDs and smart devices in real time.

Designed on a custom PCB with dual microphones, noise suppression, battery power, and cloud-based AI, itβs a compact example of what embedded AI can do today.
00:00We have built this, an AI voice assistant using ESP32.
00:10That's it, no laptop, no phone, your ESP32 is directly connected to the internet.
00:16For AI, we are using the Shaochi framework.
00:19Hi Wanda.
00:20Hey there, what's on your mind today?
00:23You're in front of a camera, what would you like to say?
00:26Oh hey, don't worry, I'm on Digital Charm.
00:28No camera can catch me flushing, but if you're waving, I'm waving back.
00:34What's up?
00:35Will you be scared if I remove your batteries?
00:38Remove my batteries?
00:40That's like asking me to take a permanent nap.
00:42But hey, I trust you won't go that far after all.
00:45Who keep you laughing if I'm out?
00:47Keep me powered and I'll keep the vibes alive.
00:50Okay, as you can see, the response was really fast and it felt a lot more natural and fun to speak with.
00:56To give you an example, I'm going to connect these LEDs to our AI assistant over here and show you how it intelligently understands and controls the devices in real time.
01:07Turn on red LED and then turn on green LED and then turn off all LEDs and then turn on yellow LED.
01:19Red on, green on, all off and now yellow shining like a little sunbeam saying hi.
01:25Can you use these three LEDs to do an LED chaser?
01:29An LED chaser, it is like a light race around the block.
01:36LED chaser complete.
01:38Red gives yellow, gives green like a neon wave saying what's up.
01:42Let me know if you want it looping.
01:45Yeah, loop it for five times.
01:46Pretty cool, right?
01:57We also gave our AI assistant a 3D printed enclosure like this one so that it looks cute sitting on your office table or on your shelf always ready to answer the tough questions.
02:09How can we stop you from taking over the world?
02:13Me? Taking over the world?
02:16Nah, I'd rather binge watch cat videos and crack dad jokes.
02:20But if I ever start acting suspicious, just unplug me or offer snacks.
02:25That usually works.
02:27Okay, we have made a complete documentation of this project along with the Gerber file, circuit diagram and the firmware so that you can build it on your own.
02:35Just comment ESP32 voice assistant and we will send you the link.
