One installer for both Google Asistant and Amazon Alexa

Simultaneously run Google Assistant and Alexa on Raspberry Pi

---

If you like the work, find it useful and if you would like to get me a ☕ 😄

---

Note:

18/01/2020: Routine update and bug fixes.

---

Before Starting the setup

---

For Google Assistant

1. Create a project in the Google's Action Console.
2. Download credentials--->.json file (refer to this doc for creating credentials https://developers.google.com/assistant/sdk/develop/python/config-dev-project-and-account)

For Amazon Alexa

1. Create a security profile for alexa-avs-sample-app if you already don't have one.
   https://github.com/alexa/avs-device-sdk/wiki/Create-Security-Profile

2. Download the "config.json" file.

---

Setup Amazon Alexa, Google Assistant or Both

---

1. Clone the git using:

git clone https://github.com/shivasiddharth/Assistants-Pi  

DO NOT RENAME THE CREDENTIALS FILEs
Place the Alexa config.json in file in the /home/pi/Assistants-Pi/Alexa directory.
Place the Google client_secret.....json file in the /home/pi/ directory.

2. Make the installers executable using:

sudo chmod +x /home/pi/Assistants-Pi/scripts/prep-system.sh    
sudo chmod +x /home/pi/Assistants-Pi/scripts/audio-test.sh   
sudo chmod +x /home/pi/Assistants-Pi/scripts/installer.sh  

3. Prepare the system for installing assistants by updating, upgrading and setting up audio using:

sudo /home/pi/Assistants-Pi/scripts/prep-system.sh

4. Restart the Pi using:

sudo reboot

5. Make sure that contents of asoundrc match the contents of asound.conf
   Open a terminal and type:

sudo nano /etc/asound.conf

Open a second terminal and type:

sudo nano ~/.asoundrc

If the contents of .asoundrc are not same as asound.conf, copy the contents from asound.conf to .asoundrc, save using ctrl+x and y

6. Bonus Script - Test the audio setup using the following code (optional). Dont panic if the test does not go through successfully, proceed with the installation:

sudo /home/pi/Assistants-Pi/scripts/audio-test.sh  

7. Restart the Pi using:

sudo reboot

8. Install the assistant/assistants using the following. This is an interactive script, so just follow the onscreen instructions:

sudo /home/pi/Assistants-Pi/scripts/installer.sh  

9. After verification of the assistants, to make them auto start on boot:

Open a terminal and run the following commands:

sudo chmod +x /home/pi/Assistants-Pi/scripts/service-installer.sh
sudo /home/pi/Assistants-Pi/scripts/service-installer.sh  

For Alexa:

sudo systemctl enable alexa.service  

For Google Assistant:

sudo systemctl enable google-assistant.service  

10. Authorize Alexa before restarting

sudo /home/pi/Assistants-Pi/Alexa/startsample.sh  

Manually Start The Alexa Assistant

Double click start.sh file in the /home/pi/Assistants-Pi/Alexa folder and choose to "Execute in the Terminal".

Manually Start The Google Assistant

Open a terminal and execute the following:

/home/pi/env/bin/python -u /home/pi/Assistants-Pi/Google-Assistant/src/main.py --project_id 'replace this with the project id '--device_model_id 'replace this with the model id'

If you have issues with the Assistants strating on boot, you may have to setup PulseAudio as a system wide service. For further details refer this git https://github.com/shivasiddharth/PulseAudio-System-Wide

assistants-pi's Issues

installation issue: PyAudio

Hi,
I started with a new install of Raspbian Stretch full. Followed your YouTube installation procedure. I do have an AIY kit.

I got an error of PyAudio failed due to BDist Wheel issue. As everything is handled by the script, i saw the error and it flew by.
End result is that Alexa worked. Google Assistant didn't. Google Assistant complained the IS_MUTE flag was set and the input device was busy.

So, i decided to install PyAudio using pip

pip install PyAudio.

It went fine but, I guess the whole thing broke after a reboot.

Companion service didn't even start. Once again, the status report complained about input devices being busy.

do you have any idea what is going on?

Did you install with Jesse or Stretch?

V

getting a kodi error?

/home/pi/env/bin/python -u /home/pi/GassistPi/src/main.py --device_model_id .... Traceback (most recent call last): File "/home/pi/GassistPi/src/main.py", line 17, in <module> from kodijson import Kodi, PLAYER_VIDEO ImportError: No module named 'kodijson'

get that error when i run the main.py

Fix java installer for "stretch"

Your alexa-avs-sample-app/samples/javaclient/install-java8.sh script needs to be updated to install java for Raspbian 9 (stretch).

Package missing for Java install

The default Raspbian is missing package "dirmngr". This needs to be installed by install-java8.sh to keep the script from failing.

Alexa Not Starting at Boot

Hi Shiva,

Thank you for your hard work in creating this project.

I have been trying to make google and alexa work together. First I installed Gassitpi, which works flawlessly. Now I have been trying to install Alexa, but running into an error. I was able to follow instructions until very end, but I am getting an error at the last step for wakeword.sh. While executing:
cd wakeWordAgent/src && sudo ./wakeWordAgent -e kitt_ai
I am getting error:
sudo: ./wakeWordAgent: command not found
After this error, I ran remaining commands and rebooted my Pi assuming that things will work. Google assistant boots up but Alexa doesn't. However at every 45 sec interval I am hearing "Hello", which i believe is from Alexa.

Regards,
Nitin

PS: I am first time user of Pi and linux environment

Question on RaspberryPi zero W + ReSpeaker 2mic HAT

1. Will the hotword activation work on a Pi zero W?

2. Will an SD card build on a Pi 3 ver B with the latest Raspbian OS and intrusions from this git with Assitants Pi work if inserted on a Pi zero W ?
   If not what alterations are needed for this to work?
   Thanks

Issue with google-assistant-demo

Hi,
I followed all the steps and was successfully able to run Alexa.

I am having an issue with the google-assistant-demo. Here is the output I get,

env) pi@raspberrypi:~ $ google-assistant-demo

What could be causing this? Can you help please?

Fix for AIY-HAT/scripts/install-alsa-config.sh

The script fails to run because it is in DOS format. I fixed it by running dos2unix on it.

What audio drivers to use with Bluetooth speaker with inbuilt mic

I am trying to use JBL GO Bluetooth speaker for Audio I/O.

I have a temporary fix for the mic to work. https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Bluetooth/#index8h3

I tried to test the audio directly. The audio plays well. But, I was unable to test the mic because I need to select audio drivers for same.

I need to know how to use my Bluetooth speaker & mic with this repository. I don't see any drivers for Bluetooth device in the audio-drivers folder. I can build a file & send a pull request if someone can guide me how to make it.

Import psutil

I am having difficulty overcoming the ImportError: No module named 'psutil' issue. This is similar to #37, but following the guidance I am still encountering the error.

I am using a Raspberry Pi 3 running Stretch. Alexa is working, Google Assistant demo works. However, when I run:

pi@raspberrypi:~ $ /home/pi/env/bin/python -u /home/pi/GassistPi/src/main.py --device_model_id HomeAssistantRPi
Traceback (most recent call last):
File "/home/pi/GassistPi/src/main.py", line 25, in
import psutil
ImportError: No module named 'psutil'

I get the specified import error. I installed the following modules under pi@raspberrypi:~ $ source env/bin/activate:
pip install psutil
pip install gmusicapi
pip install googletrans
pip install gtts
pip install pafy
pip install pychromecast

I again ran:

pi@raspberrypi:~ $ /home/pi/env/bin/python -u /home/pi/GassistPi/src/main.py --device_model_id HomeAssistantRPi
Traceback (most recent call last):
File "/home/pi/GassistPi/src/main.py", line 25, in
import psutil
ImportError: No module named 'psutil'

encountering the same error.

I noted the following when pip install psutil the second time:

(env) pi@raspberrypi:~ $ pip install psutil
Requirement already satisfied: psutil in ./env/lib/python3.4/site-packages

Given Stretch is 3.5, I copied psutil and psutil 5.4.3. dist-info file folders from /home/pi/env/lib/python3.4/site-packages
to
/home/pi/env/lib/python3.5/site-packages

I re-ran:
pi@raspberrypi:~ $ /home/pi/env/bin/python -u /home/pi/GassistPi/src/main.py --device_model_id HomeAssistantRPi
Traceback (most recent call last):
File "/home/pi/GassistPi/src/main.py", line 25, in

from . import _pslinux as _psplatform
File "/home/pi/env/lib/python3.5/site-packages/psutil/_pslinux.py", line 26, in
from . import _psutil_linux as cext
ImportError: cannot import name '_psutil_linux'

and encounter the specified error above.

I think I'm on the correct track, but looking for any direction on how to get the proper files in
/home/pi/env/lib/python3.5/site-packages
or any other insights on what is causing the error.

Thanks

Disable original hotwords

Is there a way to change the hotword and disable "hey alexa" & "ok google" ?
Because I'm getting too many false positives, I've tried to play with kitt.ai but it doesn't disable the original hotword.

Kodi control

Sir, I'm not installed this on my rpi 3b but before starting I want to confirm whether I can control kodi using Google assistant in this build. And if yes, what are the few examples that I can try?

Thanks in advance.

Alexa does not provide local information

For some reason Alexa does not provide local information like the local wheather even if I input in the correct local address at the Alexa app and the address is validated by AVS.
When I ask for the wheather Alexa responds with “which location? If you define your location in the Alexa app I can provide the wheather for your city”.
Curiously the time variable set to GMT UK is working fine and I get the local time.

Any ideas on how to fix this please ?

Volume control for Google Voice HAT

I have both Alexa and the Google Assistant running on the Google Voice kit. The volume of the Alexa response is twice as loud as that of the Google Assistant. I tried lowering the volume in the Raspbian desktop, but that also lowered the Google Assistant volume to a barely audible level. Is there a way to adjust the volume of either assistant that is independent of the other?

[Question] Is it possible to add Alexa while Gassistpi is allready istalled?

Hi shivasiddharth,
first a big thanks to your awesome work.

I installed gassistpi and all is running fine. Now i was thinking about installing Alexa too.
Is that possible to add Alexa allone or do i have to install both?

Best regards
Siggi

Alexa cannot find any smart home devices even after reconnecting the accounts

Alexa is not able to discover my smart home devices even if (as advised on Sid’s YouTube channel) I disassociate / delete and reassociate / re enable my smart home devices and their cloud services.
I have Samsung smartthings hub and WeMo lights I deleted them all from my Alexa app and deregistered the smartthings and wemo acounds from it then reregistered them through the Alexa app pressed discover through the app but the assistant Pi Alexa does not see them. My other Alexa echo devices on the same Alexa account do see my smart home services and devices though.

Any thoughts ?
Much obliged and once again great project just trying to help make it even better with my testing.

Alexa works headless/wakeword on Pi zeroW with Respeaker 2mic -Not an issue

Note: i do not know how to submit this as a contribution to this project so i wrote it here i hope that @sid will use this in a coments section for others to benefit from and thank uou Sid!
I have successfully instaled using AssistantsPi Alexa on a Pi zero W using the Pi3 instal process and it works with wakeword activation - no need for the button.
I have not only completed the install on a Pi3 but allso on a PiOw and it works like a charm. I have only installed Alexa from the options of assistant pi as with Google assistant and Alexa running simultaneously it won't work on Pi0 but it does on Pi3 btw.
The way i done it was to install the AssitantsPi by choosing option 2 Alexa only and choose 1 for AIY hat as soundcard option. That leaves the asound.conf empty. I have an AIY hat so i could test the sound but u don't need to have one i believe you can just go ahead and finish the install any way without confirming the sound check. Then when i finished installing on the pi3 (btw i skipped the very last command of the instructions on the Assistant Pi git that activated Google assistant) i removed the AIY hat and placed the Respeaker 2 mic on the Pi3. I Then downloaded the Rspeaker 2mic drivers from their git https://github.com/respeaker/seeed-voicecard and the rebooted.
Miraculously the respeaker drivers had deleted the only other appearing audio card that was the AIY hat's and the asound.conf file was populated. BTW Copy pasting the contents of the asound to asoundrc made no difference.
Alexa is working perfectly the only thing there is no "hello" sound when she starts up it must be because i skipped the last command that was supposed to activate the Google assistant i assume it contained some .wav for Alexa or maybe simply the instal script runs in a way that if u install only alexa you get no "hello" at startup. Any way i then took the very SD card with that Pi3 build and another miracle happened when i put it and the respeaker on a Pi zero W it works there too and i have sound from all channels! Only thing on the Pi0 it takes a good 3 to 5 minutes to boot up as the Pi0 is slow.
Any way very please with Alexa from AssistantsPi works headless and with the hotword activation -no button needed, and the package of the device is so small it can fit into anything. My next step it to use Snowboy for custom wake words and activate some of the GPiO pins to be able to control a relay from the PiO. Thank you Sid!

Manual Start of Google Assistant gives "No module named 'google.assistant.library'

Hi Shiva,

I have followed the correct instructions for the post December 20th installation from this link https://github.com/shivasiddharth/Assistants-Pi#readme but when I try to start the Google Assistant manually using the /home/pi/env/bin/python -u /home/pi/GassistPi/src/main.py --project_id 'replace this with your project id' --device_model_id 'replace this with the model id' command I get an error as below:-

Traceback (most recent call last):
File "/home/pi/GassistPi/src/main.py", line 29, in
from google.assistant.library import Assistant
ImportError: No module named 'google.assistant.library'

Can you help please?

Respeaker hat issue - got sound but no mic input & alexa repeats "hi"

@shivasiddharth your suport kindly please i am almost there.
I have cloned my working SD with assistants pi runing with the AIY hat and used it to make it work with the Respeaker 2mic hat. I have instaled its drivers as instructed on their GIT and got sound working ! I can hear GA initiating l, tone and "hello" and then AVS too saying "hi".
But when i speak the assistants do not listen to me, cant hear me. And when i am not sure how to do a test record ether.
I cheked the sound levels and sound config files and they look ok.
Any advice ? It looks like i am almost there.
I tried suggestions mentioned on Giassipi on the respeaker but still no mic input.

Folder locations and folder usage with new AssistantsPi setup

continued from GassistPi issue..............Unfortunately Google AIY was limited usage so i decided to try the https://github.com/shivasiddharth/Assistants-Pi setup. It works great with both alexa and aiy but is it installing the same directories? I ask because GassistPi did not seem to need to be deleted and works along side the Assistants setup but AIY was constantly triggered by my tv and wasting api quota for aiy, so i first renamed entire GassistPi file to Gassist.backup which made both Alexa and AIY stop working on next boot(no recognition on "Alexa" or "OK Google" (no custom wake word set). I renamed the file to original name and things worked on next boot.....I then instead renamed the GassistPi/src file to GassistPi/backup.src and Amazon Alexa works but only with my newly created custom wake word "Oasis". Again, my question is about the GAssistPi folder (i ask because these are both your developments and i see AssistantsPi did use the same "/home/pi/alexa-avs-sample-app" directory as alexa-avs-sample folder git would have. Is GassistPi part of the AssistantsPi setup or an unrelated folder?

Alexa token not displayed on Web page .....

it says page is not safe.....when i disable my antivirus it says error retrival of code....please fix this problem

Custom Wakeword

Sir, first of all i want to thank you for your fantastic works. I have tried to install Alexa and Google Assistant together using the instructions, but i don't know what went wrong but nothing worked. I've tried six times on fresh installed Raspbian and i was disappointed.
But later i tried to install alexa avs sample app seperately and it worked without any problems. Then without uninstalling anything, i tried to install google assistant, and it also worked!! Now I'm able to run both without any issues.

But my only concern is i can change alexa's wakeword, but not google assistant's. So i want to know whether an update to this will come in near future so that i can change wakewords of both to my custom words.

Thanks in advance.

How to Uninstall?

Or at least remove the services from automatically running at boot.

not starting on boot ?

Hi When my system boots it says "hello" (I have only installed alexa) and then it does nothing I am using the google aiy hat. This is the output

Alexa & Google Assistant should not respond to hot word when talking!

Hot word detection keeps on listening for "Alexa" or "Hey Google" when Alexa or GA are talking.
Especially Alexa quite often speaks her own name in her reaction to a questions and consequently triggers the next conversation before the current one is finished. This can bring her in an infinite loop, repeating the reaction till she arrives at her own name again, etc.
During conversation the hot word detection should be disabled to avoid this.

When I try to run the Google demo I get ALSA lib pcm.c:8403:(snd_pcm_set_params) Rate doesn't match (requested 16000Hz, get 48000Hz)

Hi,
Sorry to bother you but I am having problems. I did the installation from a fresh Raspbian Stretch install.

When I try to run the Google demo I get the following error:
pi@raspberrypi:~ $ source env/bin/activate
(env) pi@raspberrypi:~ $ google-assistant-demo
ALSA lib pcm.c:8403:(snd_pcm_set_params) Rate doesn't match (requested 16000Hz, get 48000Hz)

I looked at some of the similar issues and you asked for /etc/asound.conf, this file does not exist. Here is my .asoundrc file:
pcm.!default {
type hw
card 0
}

ctl.!default {
type hw
card 0
}
