Overview
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.

„Alexa, who is at the door?“ - A face recognizing Arduino camera using AWS Rekognition for my grandmother
I created this project and my target is improve the comfort of my home. Taking a look around I noticed that home automation solution proposed by the big market player are too much expensive for me and, above all, I should create new wires connections between light, plug, etc.. and the control box.My idea is use what we already have without spend lot of money to buy a owner solution, so I started with arduino, my android mobile phone, some relays and my home.I have a nice home, 2 bad rooms, kitchen with living room and it was very nice tka e the control of the lights, gate and door with my mobile phone. [Mattia] have realized home automation via internet, using: [...] an Arduino 2009 with ethernet shield and the game is very easy, I send some http message to arduino, he moves some relays and give me back a JSON response. Not so hard, but the hard business is interfacing with the electrical wiring of home, with some patience I found what I need and I linked those wires at the relays. A chi non è mai capitato di restare chiuso fuori casa senza le chiavi? Beh a noi spesso e ci sarebbe piaciuto aprire il nostro cancello o porta di ingresso usando il telefono cellulare che abbiamo sempre con noi, il bisogno aguzza l'ingegno...ed ecco fatto! Ci siamo guardati un attimo in giro ed abbiamo recuperato un po' di informazioni su Arduino, la sua filosofia a "brick" ci è sembrata l'ideale per fare quello che avevamo in mente, il mio HTC Hero con Android OS ha fatto il resto. [Mattia] ha realizzato un progetto di automazione domestica usando Arduino Duemilanove e Ethernet Shield: [...]Bisogna far comunicare Arduino con il nostro telefono, la soluzione più pulita che mi è balzata in mente era quella di usare il protoccolo http per farsì che la comunicazione avvenga e JSON per scambiarsi i dati agilemente.
