Meta Voice SDK enables natural voice interactions for AR/VR apps, powered by Wit.ai.

Version 81.0 Release Notes

The Voice SDK enables you to bring voice interactions to your app experiences. Use the Voice SDK to enhance the AR/VR experience with more natural and flexible ways for people to interact with the app. For example, voice commands can shortcut controller actions with a single phrase, or interactive conversation can make the app more engaging.

Powered by the Wit.ai Natural Language Understanding (NLU) service, the Voice SDK is compatible with Oculus headsets, mobile devices, and other third-party platforms. Wit.ai is easy to sign up for, and it’s free. Using Wit, you can easily train apps to use voice commands with no prior AI/ML knowledge required. The combination of the Voice SDK and Wit.ai empowers you to focus on the creative and functional aspects of the app, while enabling powerful voice interactions.

See the Voice SDK Overview guide for information about how to get started using Voice SDK. Also, see the Unity Getting Started Guide for information about how to get started developing for Oculus with Unity, or the Scripting Reference for a detailed API reference.
