Voice Recognition Module

This product is a speaker-dependent voice recognition module. It can store up to 80 voice commands in all. Max 7 voice commands can be used at the same time. Any sound can be used as a command. Users need to train the module first before the module can recognize any voice command.

Features:

• Stores a maximum of 80 voice commands, with each voice command lasting 1500ms (one or two spoken words)
• Maximum of 7 voice commands can be listened for at the same time
• Control Methods:
  • Serial Port (full functionality)
  • General Input Pins (partial functionality). The General Output Pins on the board can generate several kinds of waves when the corresponding voice command is recognized.
• Voice commands are stored in one large group like a library. Any 7 voice commands in the library can be imported into recognizer simultaneously.
• Arduino library is supplied
• User-controlled General Pin Output

• Operating Voltage: 4.5-5.5V DC
• Operating Current: <40mA
• Digital Interface: 5V TTL level for serial interface and GPIO pins
• Analog Interface: 3.5mm mono-channel microphone connector +  microphone pin interface
• Size: 31mm x 50mm
• Recognition accuracy: 99% (in an ideal environment)
