## Description

Voice recognition module for Arduino and other boards, ideal for controlling projects via voice commands. Supports up to 80 learned commands and recognizes up to 7 simultaneously, is fully controlled via serial port or simplified via input pins, and GPIO outputs can generate signals for automatic actions. Includes microphone and operates at 5V with low consumption.
Voice recognition module compatible with Arduino and other development boards.
This is a voice command recognition module, which supports up to 80 voice commands and up to 7 simultaneous commands.
In order for the module to work, it must be taught to recognize a certain sound or word that will be associated with the desired command.
The board has 2 control methods: through the Serial Port (all functions) or through the INPUT pins (partial functions).
OUTPUT pins can generate different forms of signal, corresponding to the voice command for which it was trained.
The module comes with a microphone. Used together with Arduino and an SD card reader module, a loudspeaker can be attached for audio feedback to voice commands (see the picture below).
Specifications:
Supply voltage: 4.5 - 5.5VDC
Operating current: below 40mA
Logic voltage: 5V
Digital interface: GPIO and TTL level for the UART interface
Analogue interface: 3.5mm mono channel microphone connector plus pin interface
Recognition accuracy: 99% under ideal conditions
Dimensions mm: 31 x 50mm
