Elechouse Voice Recognition Module V3.1 and Arduino - Setup and Tutorial

[@Science.Buddies]

UPDATE May 2024: We have been getting a lot of comments about this voice recognition module not working properly. If you are having trouble we recommend either contacting the manufacturer directly for support, or contacting the seller for a refund or replacement board.

[@bobhammell6308]

Great video that covers install and training, much appreciated!

[@Cyros_Sachin]

bro plz help me.... i have purchased this module today only but while training it , it show trained successfully but when i used to load them it show untrained .... plz plz help me

[@Science.Buddies]

A lot of users have been reporting this issue lately and it appears that it might be a problem with a bad batch of boards. We recommend contacting the manufacturer for a replacement.

[@riverzin3186]

get the DF Robot Gravity voice recognition. I bought the elechouse one and it didn't work and had to fight for a refund. The DF Robot one is awesome. It's cheaper and far superior. I hooked mine up to all sorts of motors, relays etc and it worked seamlessly. So good, I bought another for my workshop.

Great video. Simple and easy explanation.

thank you although i still havent bought the module I still wanted to know how to program and connect the board,Thank you!

[@dungnguyen-si2sz]

can u help me with the error: at the very first time it said "record 0 success" but when I "load 0", it said "load 0 success; record untrained" I did all the following steps and got stuck at here, thank you so much, Sir.

Can you please help me. Every time I try to train m module it keeps saying train timeout.

[@TheDradge]

How do you access all 80 possible stored voice commands? Like what do they mean by "7 from 80 at once"? What does "at once" mean? Can't the bank of 7 be dynamically switched out?

[@abhiramsp9972]

Sir can we use and train this module with different emergency vehicle sirens so that it can recognize particular sirens?

[@Science.Buddies]

In theory it should work with any sound (not just human voices), but it is very sensitive to the distance to the sound source and its volume. So you might need to record the sirens at multiple distances and train all of them.

[@XC96-1]

What about how to do it with motors? Is it the same concept?

[@Science.Buddies]

We recommend checking out our Arduino tutorial playlist: kzbin.info/aero/PLlBVuTSjOrclb0iCMSRpS_H1lSrlSVeEm&si=lGuVZk1zaveJl_GT

[@stylecomparisonwecb6890]

my final year project is doing with voice recognition module V3.1. but i have a huge problem. voice recognition doesn't response when background noise is occur. what can i do for it. because the circuit should can be use noisy areas

[@Science.Buddies]

This voice recognition module is not as powerful as cloud-powered assistants like Alexa/Siri etc because all of the processing is local, so it is not capable of filtering out background noise. It can only respond to the exact sounds that it is trained on. One option would be to record multiple "training" sounds in the area where you expect to hear the background noise, and then make it respond to all of them. It might not be perfect but it could work better than only training a single sound in a quiet environment.

[@1tokeover]

My VoiceRecognitionmoduleV3 doesn't save any commands after I power cycle the arduino. Any ideas how to fix this?

[@Science.Buddies]

Unfortunately we're not sure, you will need to check their documentation or customer support.

[@1tokeover]

@@Science.Buddies This was so obvious I feel stupid. I wasn't uploading the code to the arduino after loading the voice commands.

[@1tokeover]

Also, the recognizer will get wiped every time you plug in the arduino with the serial monitor open.

Hello, the explanation is very nice, but I encountered some problems when applying in the serial monitor. When I type the word train 0, the phrase “Speak now” does not appear, and instead the phrase “Time is over” appears. What should I do to solve this problem?

why when I try to load my trained voice, it says record unmatched

[@jomfawad9255]

Just one question does it only recognize the voice of the person who train it? or the train setup is for the word itself no matter who's voice it will work? Thank you!

[@Science.Buddies]

This module will recognize the exact sound/voice of the person who trained it. If you are looking for a speaker-independent module then check this one out, but note that it only works with a limited set of pre-trained commands: kzbin.info/www/bejne/sGWkq2ljgtyDgJYsi=FSTBanbKRUoa1ONG

good day sir, thanks for this video. i would like to share that i encountered loading problem during the train phase. I successfully trained 4 voice commands but i can't load them. like using the following command: load 0 1 2 3 after entering this command, no one has been loaded( 0 loaded) hope anyone here can help me. thank you.

The product is too expensive i cant afford it, is there any other alternative for voice recognition? (Maybe just like cheap version of voice sensor)?

[@Science.Buddies]

Unfortunately we can't really help troubleshoot without seeing your circuit. You may have a short circuit on your breadboard somewhere or a problem with your power supply.

Hey , can I build automated scarecrow machine with this module , that will react by sensing sound of only crows and birds

[@Science.Buddies]

You could try that, but you'd need to waterproof the entire thing if you want to use it outside. Another option is to use a passive infrared (PIR) motion sensor, but that would detect any moving animal or human.

[@omartarek6658]

i was wondering if the module can handle more than 4 commands in one time i tried like 7 commands and only the first 4 are working is there is any soultion? ... and should i remove the rx and tx pins when i upload the full code to the arduino

[@Science.Buddies]

No, you should not disconnect the rx and tx pins, since the module still needs to communicate with the Arduino after the code has been uploaded from your computer. You will need to consult the Elechouse documentation regarding how many commands the module can handle at one time: www.elechouse.com/product/speak-recognition-voice-recognition-module-v3/

Hi - yes, you could do this. You may want to check out our How to Use an Arduino playlist: kzbin.info/aero/PLlBVuTSjOrclb0iCMSRpS_H1lSrlSVeEm, and this project which is on a different topic but shows how to control a pump with an Arduino: kzbin.info/www/bejne/l4OlgZRpg5xjnM0. That project uses a small pump that can be powered directly by the Arduino, but for a larger pump you would need an external battery pack. We have several projects that show how to do that, for example this drone video: kzbin.info/www/bejne/h3_RqWWbq7CVlZI or this autonomous car: kzbin.info/www/bejne/p4bSZ5uOiLtkmJo (those are both controlling motors, but a pump is really just a type of motor).
