Voice Recognition Module This Voice Module v3 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. Parameter 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) Terminology VR3 — Voice Recognition Module V3 Recognizer — a container where acting voice commands (max 7) were loaded. It is core part of voice recognition module. For example, it works like “playing balls”. You have 80 players in your team. But you could not let them all play on the court together. The rule only allows 7 players playing on the court. Here the Recognizer is the list which contains names of players working on the court. Recognizer index — max 7 voice commands could be supported in the recognizer. The recognizer has 7 regions for each voice command. One index corresponds to one region: 0~6 Train — the process of recording your voice commands Load — copy trained voice to recognizer نعتذر الشراء من الموقع متوقف مؤقتا We apologize : purchasing from our website is temporarily stopped
