LuxtechPro Speech Recognition Module ELECHOUSE Voice Recognition V3 Interface 5V TTL Level UART/GPIO

This module is a compact and easy-control speaking recognition board. It 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. It 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. We already know that Voice Recognition module V2 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. 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: 31mm x 50mm. 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. Arduino library is supplied. Easy Control: UART/GPIO. User-control General Pin Output.
