Description

The ACEBOTT Voice Recognition Module V3.0 is a dedicated hardware module designed for embedded voice control applications. It processes audio input through its integrated microphone and onboard digital signal processor (DSP) to perform keyword spotting and command recognition entirely offline, ensuring privacy and reliability without cloud dependencies.

Communication with a host controller is handled via a simple UART serial interface at 9600 bps, transmitting recognized command IDs. The module’s Broadcast Easy-Plug connector system eliminates the need for soldering or complex wiring, making it ideal for rapid prototyping and educational projects requiring hands-free control.

Key Features

  • Offline Voice Engine: Local processing of up to 80 voice commands eliminates latency and privacy concerns associated with cloud services.
  • Easy-Plug Connectivity: Broadcast-style connector enables quick, reliable daisy-chaining or direct connection without soldering.
  • Optimized Signal Chain: Features a high Signal-to-Noise Ratio (SNR ≥ 60 dB) and calibrated microphone sensitivity for clear command capture in varied acoustic environments.
  • Low-Power Operation: Designed for efficient 3.3V DC operation, suitable for battery-powered portable devices and IoT nodes.
  • Robust Communication Protocol: Utilizes a stable UART serial protocol for reliable data exchange with host microcontrollers.
  • Compact Form Factor: Small PCB footprint (24mm x 46mm) with standardized 3mm mounting holes for secure integration into enclosures.

Applications

  • Smart Home Automation: Voice-activated control for lights, fans, and appliances using Arduino or ESP32-based hubs.
  • Educational Robotics: Hands-free command input for robot navigation, arm control, and interactive STEM demonstrations.
  • Accessibility Devices: Creating assistive technology interfaces controlled by pre-programmed voice commands.
  • Industrial Human-Machine Interface (HMI): Implementing voice control for hands-busy scenarios in workshops or kiosks.
  • IoT Prototyping: Adding voice command functionality to Raspberry Pi or STM32-based sensor nodes and data loggers.

Frequently Asked Questions

What is the operating voltage and how do I power this module?

The module operates strictly at 3.3V DC. Applying 5V will damage it. Connect the VCC pin to a regulated 3.3V source from your microcontroller (e.g., ESP32, 3.3V Arduino pin) and ensure a common ground (GND) connection.

How do I communicate with the module and what is the default protocol?

Communication is via UART serial (TX/RX) at a default baud rate of 9600 bps. You connect your microcontroller's TX pin to the module's RX pin and vice-versa. The module sends packetized data containing the ID of the recognized command.

Can I customize the 80 voice commands, and does it require an internet connection?

Yes, the command phrases are customizable using dedicated configuration software provided by ACEBOTT (not included in the package). All recognition is performed offline by the module's onboard processor; no internet or cloud service is required at any point.

Is this module compatible with 5V Arduino boards like the Uno?

For 5V Arduino boards, you must use a logic level converter on the UART lines (TX/RX) as the module's I/O is 3.3V logic. Direct connection to 5V pins risks damage. Power must still be supplied from a 3.3V regulator.
