Audio prompts: mark overlapping speech before assigning speakers

Decision in practice

A driver calls the warehouse at 14:27. Two people talk at once while one says 'forty-four' and another says 'forty-seven'. The initial transcript assigns both phrases to the driver and turns the call into a false agreement about delivery quantity. The revised contract emits an overlap interval, two uncertain phrases, and speaker IDs S1 and S2 without names. A reviewer listens to the source segment and confirms that the driver said 47; the other voice remains unidentified. The inventory discrepancy still requires the signed document check. The audio result cannot replace it.

Audio AU-152; interval 02:13-02:19; overlap: true.
S1: 'forty-seven' [reviewed]; identity: driver [verified separately].
S2: 'forty-four' [uncertain]; identity: unknown.
No consensus statement; quantity remains disputed.
Review: replay source audio from 02:11 through 02:21.

Performance and operating cost

For a recording of duration T, one transcription pass is roughly proportional to T in media processed; replaying J disputed spans adds the sum of their durations. Word-level timestamps and diarization increase output size and review time. Send only the relevant interval for a second check, but retain enough lead-in to identify turns. The operational cost is not just model latency: human listening and identity verification may dominate. Track word errors, missed overlaps, and wrong-speaker attributions separately, because a readable transcript can still assign a statement to the wrong person.

Common Mistakes

• Do not force one speaker label across overlapping voices.
• Do not turn an uncertain phrase into an agreement between parties.
• Do not equate a model-assigned speaker ID with a verified identity.
