Introduction

The Vivox Core SDK is an engine-agnostic voice and text chat system that brings in-app communications to your project.
Vivox SDK provides the following core capabilities:
  • Cross-platform functionality
  • Directed voice and text communication services
  • Group voice and text communication services
  • Presence 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.
Optionally, game developers can provide additional capabilities by integrating their game server with Vivox servers through the Vivox Server to Server Web API, which is a simple XML over HTTP protocol that you can access by using a variety of server technologies.
