Acoustic echo cancellation (AEC) removes the sound coming from the loudspeaker before it re-enters the mic, so callers do not hear themselves delayed. Classic signal processing handles most of it; AI hybrids improve hard cases like double-talk.

AI for Video: A Complete Guide to Intelligence in Video Products: From Real-Time Pipelines and Agents to Serving, Cost, Compliance, and Verticals
Echo cancellation breaks most visibly during double-talk, when both people speak at once on speakerphone. This volume covers echo cancellation in the real-time context: classic AEC with AI hybrids, where AI plugs into the WebRTC pipeline, call latency budgets, and serving cost per stream-hour. Written by Nikolay Sapunov, CEO at Fora Soft.
Users still hear echo on speakerphone despite echo cancellation?
