Voice Recognition Module V3

Voice Recognition Module is a compact and easy to use speech recognition board that can be easily interfaced with Arduino. 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 letting it recognise any voice command. The Voice Recognition Module allows you to control your device using just your voice.Voltage: 4.5-5.5VCurrent: Digital Interface: 5V TTL level for UART interface and GPIOAnalog Interface: 3.5mm mono-channel microphone connector + microphone pin interfaceSize: 31mm x 50mmRecognition accuracy: 99% (under ideal environment)Support maximum 80 voice commands, with each voice 1500ms (one or two words speaking)Maximum 7 voice commands effective at same timeEasy Control: UART/GPIOUser-control General Pin OutputRecogniser — a container where acting voice commands (max 7) were loaded. It is the core part of the 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 Recogniser is the list which contains names of players working on the court.Recogniser index — max 7 voice commands could be supported in the recogniser. Therecogniser has 7 regions for each voice command. One index corresponds to one region: 0~6Train — the process of recording your voice commandsLoad — copy trained voice to recogniserVoice Command Record — the trained voice command store in flash, number from 0 to 79Signature — text comment for record 10. Group — help to manage records, each group 7 records. System group and user group are supported.
