Frame-level speaker embeddings enable efficient CPU streaming diarization

FASTDIAR processes audio once, produces speaker embeddings every 80 milliseconds and clusters them online with a fixed 960-millisecond delay.

Torgashov and Köpüklü present a streaming system for identifying who speaks when without repeatedly encoding overlapping audio windows.

The authors converted a speaker-recognition architecture, normally designed to represent complete utterances, into a causal frame-level encoder.
