Install Alexa on Raspberry Pi 4

Here's how you can turn your raspberry pi 4 (or 3) into an Amazon Alexa. It's even easier than a Google Assistant and has lots of applications.

I may earn commission if you purchase from the links below:

INSTRUCTIONS:
0:00 Intro

4:20 Access your pi's terminal - I'm using ssh

4:38 Run in the terminal:
cd /home/pi/
mkdir sdk-folder

cd sdk-folder
mkdir sdk-build sdk-source third-party sdk-install db

cd /home/pi/
sudo apt-get update

sudo apt-get -y install \
git gcc cmake build-essential libsqlite3-dev libcurl4-openssl-dev libfaad-dev \
libssl-dev libsoup2.4-dev libgcrypt20-dev libgstreamer-plugins-bad1.0-dev \
libnghttp2-dev nghttp2 gstreamer1.0-plugins-good libasound2-dev doxygen

cd /home/pi/sdk-folder/third-party
cd portaudio
./configure --without-jack
make

cd /home/pi/sdk-folder/third-party
cd curl-7.67.0
./configure --with-nghttp2 --prefix=/home/pi/sdk-folder/third-party/curl-7.67.0 --with-ssl
make

6:13 Download and build the AVS Device SDK
cd /home/pi/sdk-folder/sdk-source
cd /home/pi/sdk-folder/sdk-build
cmake /home/pi/sdk-folder/sdk-source/avs-device-sdk \
-DGSTREAMER_MEDIA_PLAYER=ON \
-DPORTAUDIO=ON \
-DPKCS11=OFF \
-DPORTAUDIO_LIB_PATH=/home/pi/sdk-folder/third-party/portaudio/lib/.libs/libportaudio.a \
-DPORTAUDIO_INCLUDE_DIR=/home/pi/sdk-folder/third-party/portaudio/include \
-DCURL_INCLUDE_DIR=/home/pi/sdk-folder/third-party/curl-7.67.0/include/curl \

Build the sample app (or just run "make" to build the whole SDK)
make SampleApp

On my remote machine I run:

8:40 Generate config

cd /home/pi/sdk-folder/sdk-source/avs-device-sdk/tools/Install

/home/pi/sdk-folder/db \
/home/pi/sdk-folder/sdk-source/avs-device-sdk \
-DSDK_CONFIG_MANUFACTURER_NAME="raspberrypi" \
-DSDK_CONFIG_DEVICE_DESCRIPTION="raspberrypi"

9:08 Set up audio:

Then add
"gstreamerMediaPlayer":{
"audioSink":"alsasink"
},

to the space above "cblAuthDelegate"
Ctrl + S to save then Ctrl + X to exit the nano editor

Run the following to find your card and device numbers:
aplay -l
arecord -l

Make a .asoundrc file:
sudo nano ~/.asoundrc

Copy and paste the following (changing card and device numbers if necessary):
pcm.!default {
type asym
type plug
}
type plug
}
}

Ctrl + S to save Ctrl + X to exit

Kill pulseaudio: pulseaudio -k

Authorize and run your Alexa:
cd /home/pi/sdk-folder/sdk-build

I hope you found this helpful! Happy coding

Sam, a great tutorial as always! Can you please let me know if this project supports music playback? Can I expect same features that Echo offers?

[ahmedadel]

[larszxda]

[draco]

Please make another video with latest options

[RodrigoJustideOliveira]

Hey thanks for the video! I'm installing on a different SBC: Orange Pi PC with Armbian (Raspbian-like). The installation process is complete, and it seems to be running, I can even find it in the Alexa Android app. But when I say something into the microphone I don't get any sound. Any idea? Does Alexa use Pulseaudio or Alsamixer?

[tiagosoares]

Great video !
I managed to make it work here at home.
But I live, I ask in Portuguese Brazil and Alexa is answering me in English. Question: how do I keep asking Alexa questions in Brazilian Portuguese?
answer me in my language Brazilian Portuguese

[sanskarmudgal]

I am going to build this
I have some doubts
1. How can I add notification ring
2. How can I use raspberry pi as bluetooth audio receiver
3. Can we able to connect this with alexa app

[lastcouponbonus]

Hi, how did you make the SDK interact with the home automation objects? I tried to start the sdk but it says only certified devices can do this.

[duongvuong]

Hi, I like your video a lot and it helped me set up alexa successfully. However, I've tried to follow through your link using snowboy but it seem to be outdated and might not able to support any problem that could occur. Can you suggest me some other ways of enabling wake word? Much appreciated

[paarthmittal]

I got my alexa up and running. But how to support music playback. Please help.

[MTEX-trvd]

I tried to recreate the project but failed the AVS is no longer free 😢
