Install Raspbian OS on raspberry pi
First of all, we have to install the latest Raspbian OS in our Raspberry Pi 3B+. I already a dedicated post for this. Please visit the following post for the guide of Raspbian OS Installation.
Install alexa google assistant raspberry pi
To Install alexa google assistant raspberry pi, Follow these posts.
Do not make those two to run on startup as said on those posts using crontab.
Now we have to make a python file in any directory. I am creating a file names “assistant.py” inside home directory.
Now make that file executable by going to properties of the file and make all 3 options to anyone.
Now we have to paste the following code in the file and save it.
import os os.system("nohup bash /home/pi/Desktop/alexa.sh > /dev/null 2>&1 &") os.system("nohup bash /home/pi/Desktop/google.sh > /dev/null 2>&1 &")
Here we are basically calling those two shell scripts (made in Alexa & google assistant posts) on the desktop using python 3. Here scripts will run in background and output will be ignored.
Start on Boot alexa google assistant raspberry pi
To run Alexa & Google assistant both on startup, we have to add this python file into crontab. To do this first run the following command.
After this add the following line in last line.
@reboot python3 /home/pi/assistant.py
Now Save it by pressing Ctrl+O & exit it by Ctrl+X.
From now, after every startup of Raspbian OS, Alexa & Google Assistant will start automatically and run Simultaneously.
You will notice high CPU (>80%) usage for running in background. So I do not prefer running it on start up. I recommend start it manually from mobile using VNC remote session.
To disable automatic startup, just remove the line you added in crontab & you will be done.
For asking question to Google assistant say “OK Google” followed by your question.
To ask question to Amazon Alexa say “Alexa” followed by your question.

Some times you may get no sound on speakers for alexa google assistant raspberry pi. To fix it check your default sound device settings. Sometimes we have multiple sound card installed. So the last installed sound device is set to default by our OS. Then we have to manually select the sound output device to get sound.
Sometimes your voice may not recognized. The reason behind it your mic has issue. Remember one thing, Raspberry Pi 3B doesn’t have support of Mic. We have to use external USB sound card for alexa google assistant raspberry pi.
