Overview
The Yahboom voice interaction module integrates offline voice recognition and voice broadcast in one board. It uses the CI1302 voice chip solution with a built-in neural network processor, and supports deep learning noise reduction and echo cancellation for clearer pickup and playback. The module includes an on-board microphone and high-fidelity speaker, supports Chinese and English entries (language can be switched through firmware), and provides a stated recognition accuracy of up to 99% with a stated recognition range of up to 5 m.
This module supports customization of wake-up words, command words, playback timbre, volume, and recognition sensitivity. Preset word libraries are provided, and users can modify command words via a dedicated web workflow, generate new firmware, and update the module through the Type-C interface.
Key Features
- Voice recognition + voice broadcast integrated on one module

Details
Add offline voice interaction to educational robotics builds, from small rover cars to arm and legged-robot demos.
Offline voice recognition and voice broadcast are integrated on one compact board, with a built-in microphone and speaker.
Chinese/English command libraries can be customized, then updated to the module through the Type‑C interface.
Edit wake words and command words using the provided word libraries, then generate firmware for your own project needs.
Tune timbre, volume, and recognition word sets in the tooling workflow before compiling updated firmware.
Firmware writing tools are provided for updating configurations after changing commands or sensitivity settings.
Deep learning noise reduction and echo cancellation help improve pickup and playback in typical indoor environments.
Choose active or passive broadcast modes depending on whether the host triggers playback or the module responds directly.
The onboard coprocessor outputs recognition results over UART or IIC, while Type‑C is used for firmware updates.
Key specs at a glance, including interfaces, language support, and onboard storage capacity.
A preset command library supports common robot actions and can be adapted for your own wake word and commands.
Clear wiring examples help connect the module to MCU boards over serial or to embedded hosts over USB.
The slotted mounting design fits M3 hardware for easy installation on chassis plates and enclosures.
Tutorials and sample code folders cover module setup, serial communication options, and ROS voice interaction workflows.
