Bird Call Identifier Kit v2 - Offline Voice Robot with ESP32-S3 Edge Impulse
Bird Call Identifier Kit v2 – Build an Offline Voice-Controlled Wildlife Research Robot
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a small robot that rolls silently through forest undergrowth, responding only to your voice — no internet, no remote control, just spoken words like “forward”, “back”, “left”, “right”, and “stop”. With the Bird Call Identifier Kit v2, you assemble exactly such a machine, then train and embed a custom keyword-spotting model on the ESP32-S3 using Edge Impulse. The result is a fully offline voice-controlled companion ready for wildlife observation, field research, or any exploration where quiet, hands-free steering matters.
What You'll Build
You’ll construct a 2WD mobile robot on an ESP32-S3, equipped with an I2S digital microphone and motor driver. After uploading your Edge Impulse model, the robot moves instantly to voice commands. The entire speech recognition pipeline runs on-device, making it usable in remote locations where connectivity is unavailable — ideal for tracking birds, mammals, or following research transects without disturbing the environment.
What You'll Learn
- Collect and label audio samples for a custom keyword dataset
- Train a compact neural network on Edge Impulse and export a C++ library
- Deploy an ML model on ESP32-S3 and interface an I2S microphone
- Write motor control logic triggered by real-time speech classification

Why Buy This Kit Instead of Sourcing Parts Separately
| Factor | Sourcing Separately | Compoden Kit |
|---|---|---|
| Compatibility checks | You verify every part | Pre-tested as a system |
| Build support | Forums and scattered tutorials | AI companion trained on this exact project |
| Time to first working build | Days of debugging | Hours, with step-by-step guidance |
| Shipping coordination | Multiple sellers, multiple delays | One shipment from Bengaluru in 3-5 days |
Who This Kit Is For
Designed for CBSE Class 11–12 students exploring AI and robotics, B.Tech ECE/EEE undergraduates tackling a voice-control mini-project, and Smart India Hackathon teams prototyping an offline interface. The hardware is also suitable for ATL tinkering labs and wildlife clubs wanting to build an observation bot without writing complex firmware from scratch.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to open the AI companion, which walks through each wiring step and model training error. For additional help, drop a message on WhatsApp and you'll hear from us within hours.
Can I use this kit to identify actual bird calls?
Yes — the same INMP441 microphone and ESP32-S3 can be retrained with a bird song dataset on Edge Impulse. After this project, you can repurpose the hardware to classify species by their calls, all offline.
Do I need to know machine learning beforehand?
No. The AI companion explains how to record voice samples in Edge Impulse, train a keyword-spotting model, and deploy it — all with zero ML experience. You follow a guided workflow that takes about an hour.
Is the robot durable enough for outdoor use?
The 2WD chassis and TT gear motors handle grass and packed soil reasonably well. For very uneven terrain, consider adding larger wheels; the motor driver can drive up to 2A per channel, leaving room for upgrades.
Wildlife Research — Edge Impulse speech model on ESP32-S3 recognises forward, back, left, right, stop — fully offline voice robot.
