DIY Alexa: Create Your Own Voice Assistant with ESP32 & TensorFlow Lite!

We've been building towards this project in the previous set of videos. And we're now ready to build our very own DIY Alexa!
All the code for this project is on GitHub - github.com/atomic14/diy-alexa
What are we building - 1:15
Wake Word Detection - 2:27
Command Recognition - 11:47
Digging into the code - 16:30
What's life all about Marvin? - 21:52
To detect the wake words we stream audio from either an I2S microphone or from the ADC. The wake word detector looks at a 1-second window of audio. The spectrogram of the audio is calculated and fed into a TensorFlow Lite model.
Once we detect the wake word we stream the audio up to wit.ai to recognise the user's intent.
It works surprisingly well for such a small model, there are improvements that could be made with more training data.
I'll leave the access token for wit.ai live for as long as I can, but at some point, you will need to generate your own wit.ai application.
Let me know how you get on in the comments!

It's definitely starting to push the limits - but I think it's easy to forget just how powerful the ESP32 is. One of the problems is the size of the models which can get quite large (relative to the amount of RAM we have to play with). Processing time is also a factor especially when trying to do real time as in this project.

[@paulsimpson9544]

I've a follow on question if you don't mind.. I see you using the Arduino framework, but also have the esp IDF icon in platform Io. Do you have any particular preference? I'm considering switching to the IDF as I'm already using xtimers. I like the idea of know control, but also like the easy access to the Arduino ecosystem of libraries..

[@atomic14]

I've been mixing in quite a lot of functions from the IDF with my Arduino code. But it seems the IDF that comes with Arduino is now quite out of date. I've been trying to get Arduino working as a component in the IDF so I can use the latest IDF but still take advantage of the Arduino eco system but I've not had much luck. For my Asteroids game I did it all in the IDF - mainly because I wanted to use the PSRAM with malloc and there's not way to do that when using Arduino. But I really missed simple things like uploading firmware OTA - especially with my custom board not having a USB port... I think, unless there's a compelling reason (APIs that aren't available from the IDF when using Arduino) then I'd be tempted to stick with Arduino. If you aren't using any libraries or you can easily port them over then IDF is definitely worth giving a go. But, I don't think there are any huge advantages to it.

[@ankitthealchemist]

Hey! great work dude!! could we implement the simple command like "turn off the light" offline, just like the wake word detection?

[@atomic14]

I'm looking at this right now - it is a more difficult problem than the simple wake word detection. The model needs to have an output for each possible command word which means it is a larger model so will take longer to run on the ESP32. Hopefully, I'll be able to do another video soon showing it working - though just to be clear, this would be very limited commands - like: "on", "off", "left", "right" etc...

I'm having a look at that right now, got slightly sidetracked looking at building an AGC. It's possible to a limited extent, the command dataset does contain some other words that we can try using. Getting performance from a small enough model looks doable. Hopefully should have something up this week,

[@rolyantrauts2304]

Also many thanks as didn't realise tensorflow was and will do the job on an ESP32. There is a lack of opensource linux beamforming algs, which you have probably just solved. Esp32 is so relatively cheap that a distributed microphone array where the mic with highest keyword match is used for that ASR session. Vosk has a streaming API alphacephei.com/vosk/ just needs a streaming RTP protocol with current keyword match info and no beamforming needed as nearest mic automatically used...

[@atomic14]

Sounds interesting - the only issue you may start to hit performance issues with processing multiple microphones at once. Currently the wake word detection takes around 100ms so you may start running out of CPU time with more than one or two microphones. You might also hit memory issues with the audio buffering - though using a wrover module might fix this.

[@rolyantrauts2304]

@@atomic14 I dunno thought I would ask you as a total noob with ESP32 but on linux irrespective of process power we still lack opensource beamforming. The pulseaudio addition just doesn't work, don't think it ever did prob hence why upstream its been dropped from webrtc. What I am thinking is that we are not 'processing' multiple microphones at once the I2S data for mono is just doubled and the L/R hi/lo word select is not used. A single channel would be fed into a delay buffer and then I guess just summed with the inverse of the current value of the other channel? It is really a single channel in a short delay ring buffer of the speed of sound distance and what is present on the other I2S is just subtracted. For a noob who is blankly staring blankly at a $5 aliexpress wrover and brief journey of documentation it makes curious if you could with 2x cores but to be honest yet haven't a clue how :) I can not even work out if http streams are just client or you can create a server stream or if you could present AMR-WB on a port?!? Just got my fingers crossed it might perk your interest.

[@rolyantrauts2304]

@@atomic14 PS the lack of beamforming was that each ESP32 could be a streaming KWS to a central ASR. Broadcast from KW to silence with some metadata of KW hit score and a central ASR would be able to use best KW hit score so an array of esp32s could be a distributed array with best and nearest always used.

[@dariovicenzo8139]

Great video! What I don’t understand (Im at the basic of TF) why we need to use a cloud service AI when we are trying to make an edge device? So in other word we are losting the advantage to realize an edge system if we need a cloud service. So I could avoid the lite model and make all the stuff in the cloud using the esp32 as audio transmitter. I hope I understood well the purpose of facebook service. Thanks.

[@atomic14]

Hi Dario, that is a very good question. One of the issues with using the ESP32 as an audio transmitter and doing the wake detection in the cloud is privacy concerns - you really want the user to be in charge of when the device is actively listening and sending your data to a third party service. So you really want the device doing the wake word detection and only sending audio data to the internet once the wake word has been detected. Currently, doing full intent recognition on the edge is too difficult on a device like the ESP32 - however, there is software for the raspberry pi that looks very promising - rhasspy.readthedocs.io/en/latest/

[@atomic14]

Hey John, definitely not a silly question, the audio is normalised and then we calculate the spectrogram of the normalised audio. The log operation is applied to the spectrogram output. The spectrogram can end up with some very large values and the log operation brings them down into a more sensible range for the neural network to train against.

​@@synesthesiam What great people here! Thank you for Rhasspy! I'm currently working my DIY Video Doorbell (ESP32 Cam) and Face Detection with OpenCV. You know the drill. But the video soon will be finished and after that my smart doorlock will get some spotlight... but after that! I will definitly spend time on this! This is super exiting and needs more attention. Hope i'll find time for this, soon.
