Same recording, four methods: who said what?

Play the audio and follow the subtitles. Each word is colored by the speaker that method assigned; a red underline means it disagrees with ground truth. Source: Harper Valley Bank (CC BY 4.0) — no patient audio.

What each method knows: AWS and W+ECAPA self-enrolled are fully blind — profiles come from the recording's own clusters, with no outside reference audio. W+ECAPA enrolled and FT v2 were given about 20 s of reference audio from each person's clean channel — available for care partners in the archive, rarely for patients. Compare the first two for a fair test, the last two to see what enrollment adds.

The other methods only label; they never split the audio. FT v2 actually extracts it — this is the per-person output.
