Voice Command Recognition

Get inspired

Talking to your car is now possible with AutoPi. Insert a microphone in your AutoPi and send voice commands to your vehicle like K.I.I.T. from Knight Rider.

Disclaimer: this feature is not present on our out-of-the box devices. You can implement these features yourself or with our help.

Constant awareness of your surroundings

A collision prevention assist helps you maintain distance to cars in front of you, but this system is not standard in all cars. With the AutoPi TMU device, this can be a standard. With built-in audible alarms, the AutoPi TMU device is able to warn you if you don’t keep a safe distance to cars around you.

However, it doesn't only warn you about the vehicles. The collision prevention system monitors all moving and stationery objects in front of you, such as pedestrians, animals and other objects. You can also connect an external rain sensor to the device and it can warn you about driving behavior in dangerous weather conditions. The AutoPi TMU device will then talk to you and warn you about any kind of hazards.

Audible parking-space measurement

The AutoPi device can give you voice commands, that will give you an overview on how much space you have behind or in front of your vehicle. But there is more to that.

Audible alarms from the built in speaker in the AutoPi can warn you about objects you cannot see. Even voice notifications can be given.

You can read more about in our talking car feature blog.

No more annoying repairs caused by bumps and scrapes

If you connect a Raspberry Pi HUD display and parking sensors to AutoPi device, it is possible to see the surroundings on the HUD display in real-time.

How you can achieve this:


Firstly, you can basically use external microphone that can be connected to AutoPi device via an integrated USB, as long as it is compatible with Raspberry Pi. Furthermore, you will need to get a few supplies to complete this task. You will need;


Get your external microphone and insert it to your AutoPi TMU device.


Go to your AutoPi Dashboard on AutoPi Cloud, integrate the Google Assistant SDK with your AutoPi TMU device.


You should now be able to speak a command to your device, using the USB microphone, and then send the recorded action to Google for parsing. The device initiates the action, based on the result from Google.


The speaker application from your device, parses the text string and initiates the action found from the string, in this case the OBD subsystem. The OBD subsystem routine is triggered and it sends a command on the CAN bus through the ODB port.


Lets say that your command is to roll down the window. The window in your car rolls down. The speaker subsystem routine is triggered. It sends the text to be spoken to Google to translate it into a sound file. Google returns the sound file, and speaker subsystemplays the sound file to the user.


Congratulation, you are now able to create all types of cool action for your car. Be creative and enjoy your new car.
