Speech Recognition Engine is an extensive software library that allows anyone to quickly and easily interact with devices and machines by talking. It was developed by Cyberon, the worldwide leader in speech recognition, with ease of use and compatibility in mind for instant integration into new applications or existing solutions.

Speech Recognition Engine is compatible with multiple Arduino boards and with the Arduino IDE and requires no additional hardware, software or internet connectivity.
Its AI/ML engine understands commands defined through text input in 40+ languages – regardless of the speaker’s actual voice, tone or accent. This means multiple wake-up words and sequences can be quickly configured, and there is no need to retrain for different users.

Key benefits include:

  • Powerful library with integrated AI/ML engine for phoneme-based modeling
  • Recognition of multiple wake-up words and sequences of commands
  • No vocal training required, commands configurable through text input
  • Support for 40+ languages, independent from accent variations
  • One configuration for multiple speakers, without retraining
  • Recognition on the edge, no need of additional HW/SW or connectivity
  • Suitable for noisy environments
  • Expand existing projects with speech recognition capabilities
  • Compatible with multiple Arduino Nano and Portenta products
  • Compatible with Arduino IDE and Arduino CLI

Industrial-grade speech recognition

Speech Recognition Engine was developed in partnership with Cyberon, a leading embedded speech solution provider, to be part of Arduino Pro’s growing ecosystem of advanced professional solutions.

Forget the training period

Your next smart device can immediately understand every major language in the world, regardless of the speaker’s tone or accent. How? Speech Recognition Engine uses text input to define voice commands, translating them into instant results.

Infinite applications

Speech Recognition Engine is ideal for industrial and building automation applications such as hands-free control of machinery, equipment and devices of all kinds, but also for any situation where multiple people may need to interact with objects using their voice: information kiosks, vending machines and lockers, smart beds in hospitals, emergency call systems and more. 

Hear, hear!

Speech Recognition Engine helps machines and devices understand multiple users without requiring specific training for individual voices. Also, it’s able to listen to the person speaking to it while filtering background noise, making it suitable for busy or crowded environments.

How may I test the Arduino Speech Recognition Engine?

In order to test the Arduino Speech Recognition Engine, you have the possibility to:

  • Start a free trial here with the limitations reported in the Tech Specs.
  • Purchase the right voucher for your board here.

How can I activate my voucher? 

You will get your voucher by email. Once received, you need to register it at this link to start developing your own custom voice recognition model. Check this documentation to learn more. 

Which are the main differences between the Free trial and the Cyberon License activatable with the Voucher?

Check the reported Tech Specs to compare the two licenses. If you would like to unlock all the limitations, feel free to contact us

How can I change the model I have already deployed on my board?

Deployed models are not customizable, but you can always purchase an additional voucher to generate a new model for the same hardware.
