Dear all in this blog I am explaining, how I have converted my old raspberry pi to an amazon echo dot like device. In my raspberry pi I have added following things additional to core modules for this:,
USB wireless microphone
USB Wi-Fi module to connect internet already inbuilt in Raspberry pi
External speaker and auxiliary sound jack to connect speaker and raspberry pi
I have also used a raspberry pi cover, which I have built using my new 3D printer please refer my earlier blogs of my assembled 3D printer
After connecting Speaker and Microphone, I have tested voice recording and play using arecord and aplay commands. Before any further setup, I have registered for a free Amazon Developer Account and created a profile for my Raspberry device.,
Steps to register a account and to create a profile in Amazon
The Device Details tab is next. It doesn’t matter much what to enter here. Pick any category, write some description, pick an expected timeline, and enter a 0 on the form next to how many devices you plan on using this on. Click Next.
Please note Amazon Music does not work on Raspberry pi device, but for music anyone can add other freely available skills
I am configuring this pi as a Alexa Eco for my home automation IOT projects, so music is not very important for me, but I can get all other information, news etc. easily in this device based against my voice search.
Now when have an Amazon Developer Account and I have created a profile for my Pi-powered Echo then I have followed bellow steps:
this has asked some questions and then started installation, it has taken approx 20mins to finish
Then I have Installed nodeJs in raspberry pi, before executing next steps. I am using latest LTS version of Node Js in my pi
cd ~/Desktop/alexa-avs-sample-app/samples/companionService and write command '
' in nohup mode
This starts the '
Then I have installed maven (a build tool)
in another window, then I have typed - cd ~/Desktop/alexa-avs-sample-app/samples/javaclient && mvn exec:exec
Then one window popped up asking to authenticate my device. On clicking Yes, this has opened up a browser window, where I have logged into my Amazon account and upon authentication it has confirmed my device tokens were ready for communication.
I have kept all command windows open as advised
Finally I have started Wake word agent in following way
cd wakeWordAgent/src && ./wakeWordAgent -e sensory (Please note , we have two options to start wake agent - Sensory and KITT.AI, but I have selected sensory option)
That’s it, my DIY Echo is now running fine. I can wake her by trying out saying 'Alexa.' You can also try the same to built your own DIY Alexa Eco, and say 'Alexa' - You should then hear a beep sound indicating that it is listening. When you hear that beep, ask any question like, 'What’s the weather?' , 'What is the current time in USA', 'What is today's major news highlights' etc. See attached video.
