A backend-focused walkthrough of the ZEGOCLOUD live digital human server API: how CreateLiveDigitalHumanAgentInstance creates a broadcast avatar, how the request and response bodies are shaped, how the stream reaches viewers over RTC or CDN, and how to drive, interrupt, and cleanly end the session.

Compare ZEGOCLOUD ZIM, Sendbird, Stream, and CometChat for building Discord-style in-app communities and channels: architecture, limits, moderation, platform coverage, and one-vendor media.

Compare the leading real-time speech-to-text APIs for live streaming on latency, accuracy, languages, and scale — and learn how captions actually get injected into a live stream under 300 ms.

A voice agent that cannot be interrupted is not a conversation partner. This guide explains what barge-in actually requires — VAD, streaming STT, turn segmentation, and interruptible TTS — and walks through implementing it end to end with ZEGOCLOUD AI Agent, including the parameters, callbacks, and latency trade-offs.

Learn how RTC 3.25.0 improves video super resolution and AI noise suppression, including API lifecycle, limits, error codes, mode selection, and architecture trade-offs.

Learn how to clone a voice for a conversational AI agent: collect consented audio, create a cloned voice ID with a TTS provider, and wire it into a real-time ASR–LLM–TTS–RTC pipeline with interruption support.

Compare ZEGOCLOUD, D-ID, Synthesia, Beyond Presence, LiveAvatar by HeyGen, and RAVATAR for live voice-agent avatars, including real-time architecture, bundled versus composable AI components, transport, SDK support, and integration trade-offs.

Seamless media delivery is a new expectation for communication platforms, where users demand uninterrupted audio/video performance. As a result, codec switching has become an essential capability for applications, enabling systems to switch between codecs. Thus, the ability to adapt to changing technical environments is what…
