Speaker diarization
Speaker diarization is the process of partitioning a recording by speaker — answering "who spoke when." It groups the audio into distinct voices and labels each transcript line accordingly. Diarization is harder on noisy or overlapping speech, which is why some tools instead separate speakers by audio channel.
In depth
Speaker diarization is the process of segmenting audio by who is speaking — the “who spoke when” problem — so a transcript can attribute each line to a distinct speaker. It's harder than transcription itself, especially with overlapping talk or many participants, and accuracy varies by tool. Some products attempt full named diarization; others use a simpler, more reliable split. Reline distinguishes your microphone from the meeting's system audio, a robust two-source attribution that reliably separates you from everyone else without guessing names it can't verify.
