Voice Recognition Module V3 compatible with Arduino

The Voice Recognition Module V3 is an upgraded version of the previous V2 model, offering several enhanced features and improvements. Here's an overview of the updated features:

1. Increased Voice Command Capacity:

• V3 supports up to 80 voice commands in total, compared to 15 commands in V2.
• V3 allows a maximum of 7 voice commands to be effective simultaneously, while V2 only supports 5 commands at a time.

2. Voice Command Organization:

• V3 stores voice commands in one large group, acting like a library.
• Users can import any 7 voice commands from the library into the recognizer, making them effective simultaneously.
• In contrast, V2 separates voice commands into 3 groups during training, with only one group (5 commands) being effective at a time.

3. Control Options:

• The module can be controlled via Serial Port (full function) or General Input Pins (part of the function).
• General Output Pins can generate various types of waves when a corresponding voice command is recognized.

4. Easy Control and Arduino Library:

• Arduino library is provided for easy integration and control.
• Analog Interface includes a 3.5mm mono-channel microphone connector and microphone pin interface.

  Specifications:  

• Supply Voltage (V): 4.5 to 5.5
• Current: <40 mA
• Digital Interface: 5V TTL level
• Analog Interface: 3.5mm mono-channel microphone
• Recognition Accuracy: 99% (under ideal environment)
• Easy Control: UART/GPIO
• Dimensions (mm): 31 x 50

  Package Includes:  

• 1 x Voice Recognition Module V3
• 1 x Microphone

Overall, the Voice Recognition Module V3 offers improved voice command capacity, simultaneous recognition of more commands, and enhanced control options compared to the previous V2 version.
