The Vivox Unreal SDK is voice and text chat system that brings in-app communications to your Unreal project.

Features

  • Cross-platform functionality
  • Directed voice and text communication services
  • Group voice and text communication services
Game developers can integrate these capabilities directly into game clients and companion applications by using the Vivox SDK.
Vivox offers additional features for speech-to-text transcriptions and text-to-speech for better accessibility for users. As well as server-side recording to help reduce in-game toxicity.
Note
The Unreal SDK does not currently support using Vivox with Unreal's Live Coding feature in Unreal 5.2.
