Introduction: Arduino Voice Recognition. (Basic)

About: Hey YOU! Yeah, I'm talking to you who is reading this. Send me ideas for instructables, like things that you are wondering how to make or build, or really anything electronically related, and I'll get back t...

Hey guys, Today we have a great project for you. Arduino Voice recognition! We use the Easy VR and an Arduino. This project will teach you how to use the easyVR for Voice recognition: Note: Voice recognition is different from speech recognition,  voice recognition recognizes only a single person's voice, while speech recognition can recognize everybody's voice.

Step 1: Part List

EasyVR-Arduino shield: here!
||
OR EasyVR: here!
--------------------------------------------------------------------------------------------------
Arduino: here!


Step 2: Wireing

EasyVR TX->Arduino Pin 13 EasyVR RX-> Arduino Pin 12. Arduino 5V-> EasyVR 5V. GND->GND|||||||||||||||| Or if you have a shield, just put it on your Arduino. (If you can't tell where my wires are running in my pictures, then refer to the Circuit diagram made on Fritzing)

Step 3: EasyVR Library

You can get the library here!
You can get the EasyVR Commander here
You can get the Arduino IDE Software here! (if you don't have it yet)

Step 4: Programming

Make sure to have the easyVR-arduino library installed. Upload one of the samples. Then open the easy VR program, and program some commands (microphone required) by recording your voice. (Read pictures)

Step 5: Congratulations! You Have a Basic Voice Recognition System Set Up

Thanks and enjoy! If you have any questions ask them in the comments field.

    Hey! thank you for this instructable! I do not have shield, just the module, so i followed your pin diagram with 13>tx, 12>Rx, 5V>5V, GND>GND and I am using the code generated by easyvr commander but when i upload it to arduino board, i get this in the serial monitor:

    Have you run into this issue?

    Hi, I have been trying to connect my EasyVR commander to the arduino but it keeps giving this error "A EasyVR Shield/Bridge device has been found but the "bridge" software is not responding or it is outdated.

    You need to manually download the updated "bridge" software to the device."

    Pls what do I do?

    Rookie_sly can YOU please let me knw is YOUr issue resolved or not , if yes it is resolved then let me know too, because i am stucked too at this point.

    Hi, I would like to ask you if you could enlighten my understanding on the use of "QuickT2SI" tool. Do you know how can I acquire a License Key for the above mentioned program?

    Also, do you know what should I do to download a wordset on my "EasyVR Module 2.0", cause I don't really understand how to do this with my "EasyVR DevKit Board"?

    Thank you in advance!!!

    QuickT2SI is for a different DEV board, which is more advanced and comes with the licence. (https://www.sparkfun.com/datasheets/Sensors/Sound/VoiceGP_DK-QuickStart_1.1.pdf)

    Good Morning,

    So if I understood correctly, I don't have to use "QuickT2SI" with the Module and the DevBoard that I have, to create "Speaker Independent Custom Grammars" ?

    Thank you.

    how many pins it consumes on arduino while using it for speech recognition?

    According the manual 60cm . More than this you should speak louder

    Hi, what's the range of the microphone? From how far away does it manage to recognize the commands and how loud do you need to say them?

    Well, the idea behind this is actually you just have to be within the room, as long as the room is quiet. Well, remember this more or less only remembers the tones said, and matches them up with information within its data-banks. So it actually just has to be in the same tone as it was originally said. (If you have a cold it won't work :( )

    what about the time response ? As i want to make it faster in real time .

    it can process any frequency as long as the mic can pick up a frequency like that. In this case, I would say yes. The whole thing is that it "records" the message and if it hears the "recorded message" then it does a specific function.

    first , thanks for your response..... am a beginner, can yo plz shw me an example of a serial data output of this circuit ??? and also is it possible to set my own voice in this ???
