Elechouse Speaker-dependent Voice Recognition Module V3 Compact Speaking Recognition Board Support 80 Voice Commands

Description:
- Voice Recognition Module is a compact and easy-control speaking recognition board.
- This product is a speaker-dependent voice recognition module. It supports up to 80 voice commands in all. Max 7 voice commands could work at the same time. Any sound could be trained as command. Users need to train the module first before let it recognizing any voice command.
- This board has 2 controlling ways: Serial Port (full function), General Input Pins (part of function). General Output Pins on the board could generate several kinds of waves while corresponding voice command was recognized.

What’s new?
- We already have Voice Recognition module V2. It supports 15 commands in all and only 5 commands at the same time.
- On V2, voice commands are separated into 3 groups while you training it. And only one group (5 commands) could to be imported into Recognizer. It means only 5 voice commands are effective at the same time.
- On V3, voice commands are stored in one large group like a library. Any 7 voice commands in the library could be imported into recognizer. It means 7 commands are effective at the same time.

Parameters:
- Voltage: 4.5 - 5.5V
- Current: <40mA
- Digital interface: 5V TTL level for UART interface and GPIO
- Analog interface: 3.5mm mono-channel microphone connector + microphone pin interface
- Size: 47 x 30mm
- Module net weight: about 17.6g
- Recognition accuracy: 99% (under ideal environment)

Features:
- Support maximum 80 voice commands, with each voice 1500ms (one or two words speaking)
- Maximum 7 voice commands effective at same time
- For Arduino library is supplied
- Easy control: UART/GPIO
