Voice communications often suffer from lost packets due to, e.g., radio channel fades, network errors, etc., resulting in audio glitches and poor call quality. This disclosure describes machine learning techniques to replace lost packets. By masking audio glitches and providing continuity, the replacement packets improve call quality as perceived by call participants.
