I think the i2c would be for use with something like a raspberry pi

[@harrywhite7287]

@@lio1234234 I2c is just another serial port with a specific com protocol. It can be used to communicate with anything that speaks its language. The nice thing about it is, it only require 2 pins and can be used in a multi-drop configuration so it's easy to create small (Master/Slave) networks. Down side is, it's designed to be used physically close to the other players on its network. You can hang a bunch of I2c sensors on the same two lines.

[@rklauco]

Any chance you can publish your code on some git repo? I'd have some minor tweaks to enable also ESP8266 support...

[@anferjo61]

could you help us telling us what your turn_off_all function does?

[@adnanhassen296]

The code I need it

[@darkman19693]

I looked into those Pokit meters. But i eventually got myself one of those newer meters that have a built in screen. So nice not having to find my phone to use a meter.:)

[@cometmace]

I like that you show a prototype of the robot -- just a string of LEDs to confirm that each of the robot commands is being recognized.

[@arasha2547]

You are the best human on earth You provide these projects for free to us electronics enthusiasts. Nice to meet you You are my best friend. I wish you success and health My best friend

[@kaumohlamonyane272]

Amazing little tool, this removes the need for a powerful processing device to achieve voice recognition

[@alexlo7708]

Its at least ARM64 cpu with NPU or DSP. Also high performance.

[@DavidCook42]

I love your videos, and to be honest , for me, your accent and way of speaking English keeps me hooked til the end ! Keep em coming.

[@GnobarEl]

As always, another great video! One of my projects for 2022 is to make a companion robot for my kids. A Robot to tell the time, jokes, so on so on... If you do one, for sure I will follow all your videos to build it! Please, do it! :) For now, I already bought the module, it's really powerful! Thanks for sharing!!! Have a great year!

[@amphibiland]

How's your project going?

[@CaptZenPetabyte]

This is BRILLIANT, thanks so much for sharing! Looks like this will assist with a couple of my projects as well.

[@ivovass195]

Very nice little device. It has given me some home automation ideas, thank you for showing us how it works. Cheers for the new year

[@flethacker]

You can do voice recognition on a $15 raspi pi zero and have a much larger set of commands and NLP routines as well text to speech. Though this module is super simple to setup and integrate if thats all you need

[@SatishSharma-ff5ug]

Please share it...

[@SatishSharma-ff5ug]

or give a link..thanks

[@Rainer_Landes]

offline voice recognition? Without sending any data to Alexa or Apple or whatever? Can you please give some info where to find such a solution! Thank you! I would be really glad!

[@coolthought8456]

255 command! There are so many possible combination with 255. Really cool.

[@AtomkeySinclair]

Guess you could run several in parallel all receiving the same audio, expanding any given moment by multiples of 7 commands. A robot that had a directives list for example will probably have the need for more than 7 commands at any given moment, having all N commands at ready would need multiple modules all listening. Whichever one gets a pattern match first would then send the data over UART. Now you just need a way to funnel all the UARTs into a single command processor.

[@SmallSpoonBrigade]

Possibly, but if you need more than 7, you probably want a more powerful system.

[@AtomkeySinclair]

@@SmallSpoonBrigade Ideally you're right. I don't know of an embedded version that is capable of more. The next step would be something like a Raspberry PI running software I suppose...

[@adespade119]

running on i2c that might be possible, since each module would be listening for its own 7 commands. Pretty good idea

[@AtomkeySinclair]

@@adespade119 Ideally this will just evolve into more complete system. A voice module that either supports expansion, or the software equivalent of FPGA that can compile and run on something like an ESP32. Thanks for commenting!

[@toysforboysrc]

THANK YOU so much for this very comprehensive video!! I build large scale custom rc cars, I did a taking Skyline R34 with turbo sounds and at this moment I’m building a Bugatti Bolide.

Awesome tutorial on how to use the voice commands. Your channel has helped me alot in building somethings with the arduino. I have a couple of builds loaded on my channel.

[@magnetiseur77]

Good ! Already ordered one, on Ebay (less expensive)

[@TradieTrev]

The aliexpress sales page says it can only do 80, but that's plenty enough to locally control a house without needing internet.

[@fouzaialaa7962]

this is extremely interesting !!! it will be best for home automation on the cheap !!

[@glasslinger]

Can't equal alexa! Any noise in the background causes failure. (motor running sound on robot, TV set, other people in room making noise) Also, over time your voice changes so you have to re-train it again. Sensitive to volume level. (you must be close to microphone or many fails.) Won't work for different people. Some words can't be trained successfully. (these are problems I ran into)

[@Keeping_IT_Simple]

Very interesting & easy to follow guide to this board ... Think I'll add one to my next order ... Quick question...if you don't mind ? You say it can accept 254 voice commands but the specification on the listing says 80 - which is it please ?

[@TheRealStructurer]

Thanks for sharing! I can see many use cases for this 👍🏼

[@loptica62]

love the POKIT..... do you ship to Serbia? Oh, and one more thing, would like to see a dedicated tutorial about using the POKIT... BTW just curious, are you part of the crowdfunding 'pokit' project ?

[@toysforboysrc]

There’s a Movi speech recognizer and speech synthesizer board that technically also do the command. Either by closing a circuit or pwm. Not sure yet, I have not gotten deep into it yet but some of the Amazon reviews I saw were quite advanced and capable.. “the R2D2 video” but that board will be plenty to meet my needs in a 1/7 scale RC car application. Lights, fans, blow flames, start engine or engine sounds, music, and just conversation. What I’d really like is if u can also have it read out live Lipo voltages and motor temps and ESC temps. Would I be asking to much for gps/mph and G force lol?? Anyhow if you have content or experience with that board, I’m definitely going to be looking for it as I look at most of your videos!

[@isaamthalhath4359]

Dude i literally was just building a project with this lmao

[@bluebear8741]

I have questions: Can you change the text to speech voice to a different one? Can you plug it into a portable power module? does It need to be plugged into a computer for it to work?

[@ariellihan999]

GUYS, quick note here. I actually tried this on mega because I have a project using the voice recognition module in arduino mega. You guys need to connect pin 10 to tx and pin 11 to rx not the other way around. Ps: But if it works for you then I guess it's fine. Just that mine doesn't work when my tx is 11 and rx is 10

[@electronic7979]

Nice product

[@rklauco]

Looking at the specs, it would be great if it worked with 3.3V instead of 5 - would be usable with ESP8266 - connecting ESP to MQTT and you have wireless voice assistant in any room :)

[@AllTernative90]

I was thinking the same. But an Esp32 should have 5v, right? That would work I guess.

[@rklauco]

@@AllTernative90 5V power is not the problem - the signal levels on the serial interface are a bit of an issue. ESP (both 32 and 8266) is not 5V tolerant on the input pins, so providing it with 5V TX signal might fry the chip. There is level shifter option, of course, but I am 99% sure the chip on the board also works with lower voltage than 5V. I'll check it as soon as it arrives - already ordered :)

[@AllTernative90]

@@rklauco Ah I see. I'd appreciate it if you could keep me up to date, once you tried it out. :)

[@rklauco]

@@AllTernative90 So, the module arrived. Tested it with ESP and it has a problem. It does work with 3.3V, but it was getting resets as the lib is written for arduino and uses while loops without yielding back the control to ESP, therefore causing WDT resets. I was able to fix it by inserting yield(); command at line 106 and 200 of the VoiceRecognitionV3.cpp file. Since then - no problem at all, works like a charm. I've tested using SoftwareSerial connected to D6 and D7 of my wemos module (IO12 and IO13 on ESP). Works OK, training it now :) I'll have to write a code for it to send MQTT commands, but this will be perfect - I can put it to multiple rooms. My start command, btw, is "Hey, Jarvis" :)

[@AllTernative90]

@@rklauco Thanks for getting back to me and giving all the details! Could you do me a favor and test if it can also recognize sounds like a doorbell? Or does it just work with more vocal sounds? Thanks again!

[@snopz]

can we record a request like if i want to do a chat gpt robot i will say the wake word and after that i want the module to record what i say after and then when i say im finished the arduino send this voice to a speech to text api and then removes the record from the module

[@SigmaC]

Very cool! Would this work for other languages as well?

[@longdongsilver4719]

Are you seriously asking that stupid question or is it a joke?

[@ELECTRONOOBS]

Any lenguage

[@unicodefox]

It's only recognising the tones of your voice, so it'll work with any language, even completely made up words, but it will have a trouble trying to understand two people with different accents

[@farmaforpresident8138]

@@longdongsilver4719 yes, I'm seriously asking. Glad you are so smart to already know it, even though you didn't answer!

[@mikel9292]

It can only store up to 80 voice commands, not 254. You can cleary see that in the aliexpress product page, and also the parameter for the"record" command, is a number between 0 and 79, giving the total 80 voice commands. Please, update the video title, it's giving misinformation.

Hi... great video. How would i use the voice command module to hear a keyphrase or word and reply with a prerecorded wave file thru an onboard speaker?

[@MatSmithLondon]

This looks good, but I suspect people will compare with natural language processing systems. Does this require that you don’t slur words together? Must the user know that commands should be fully separated with a tiny amount of space? It seems a shame that they cannot include double the amount of storage / analysis buffer ie 3000ms. Interesting video though.

You can only max out at 7 commands a group, so you would have to do something like “Get a number from 1-7” “6” “Get a number from 30-37” “32”

Why not just use raspberry-pi-like thing and get full voice recognition? Is it only about power usage?
