  • Microprocessors such as ARM Cortex-A
  • Microcontrollers such as ARM Cortex-M

You can find the freely available models for all supported platforms, here.


Prior to Picovoice, enterprises seeking to build voice products had to choose between giving in to closed ecosystems with limited flexibility and feature bloat or creating and maintaining their own voice stack. We started Picovoice to disrupt this status quo. Picovoice is an end-to-end platform that lets you build purpose-made voice products on your terms.

Purpose-made and branded voice assistants are the next logical step in the evolution of voice as an interface. These agents may co-exist with generalist assistants such as Alexa, Google, and Siri. It is with this vision of an open and interoperable future that Picovoice decided to make wake word models freely available for all major voice assistants.

A Note on Support

These models are available under Apache 2.0. You can use them for free, even commercially, while respecting the terms of Apache 2.0 license. The community support via GitHub is available to all users. If you are commercially engaged with us, you may also request dedicated engineering support.
