Adaptive echo modeling
Tracks the acoustic path between the device loudspeaker and microphones.

Acoustic Echo Cancellation
Echo cancellation for voice calls, conferencing, smart speakers, and in-vehicle voice systems.
The objective
Clear two-way communication without device echo.
Playback from the device can return through its microphones and disrupt calls or voice interaction. AEC identifies and removes that acoustic echo path.
How it works
Engineered for the complete signal chain.
Near-end voice protection
Reduces device echo while retaining the local speaker during conversation.
Full-duplex communication
Supports more natural interaction when both sides speak at the same time.
Product-level tuning
Coordinates playback reference, delay, gain, microphones, and loudspeaker behavior.
