Official current license: https://groups.inf.ed.ac.uk/ami/corpus/license.shtml

Changes: Single contiguous excerpt from the original 16 kHz mono PCM headset mix. WAV container rebuilt; no stitching, synthetic speech, voice isolation, denoising, silence removal, speed changes or word edits. Source interval: 1050.22–1112.23 seconds.

The official download page states the license changed to CC BY 4.0 on 10 April 2017; older OpenSLR/noncommercial mirrors are not the license relied upon here. The original recording is a real non-scenario multi-person meeting; only the listed speakers have annotated words in this contiguous excerpt.

Editor preview, 2026-10-18: the complete existing 62.01-second human-solo recording and original WhisperX transcript are reused unchanged. The MP4 is an audio waveform visualization created locally with FFmpeg, not meeting footage. No new inference, speech synthesis, silence removal or stitching was performed.
