Last Updated:Nov 04, 2025

ApsaraVideo Real-time Communication (ARTC) provides a voice chat room solution that is ideal for various online engagements, such as group voice chats, matchmaking services, radio broadcasts, and gaming. You can use this solution to build a cost-effective, stable, and high-quality cross-platform voice chat service.

Integration overview

Alibaba Cloud provides two integration solutions to help you implement the voice chat room feature.

ARTC SDK-based integration

This solution requires you to integrate the ARTC SDK. We recommend this solution if you have a technical background and require a high degree of customization.

This solution provides integration examples for both Android SDK integration and iOS SDK integration.

Service architecture

Users who co-stream using the Alibaba Cloud ARTC SDK publish and subscribe to audio streams in the channel. Users who do not co-stream only subscribe to audio streams.
