# Add Speaker

`POST /v1/audios/{audio_id}/speakers`

Create a placeholder speaker on an audio file. The new speaker has zero
segments — sentence ownership gets assigned via the existing transcript
editor. Auto-allocates `speaker_id` from a monotonic counter persisted on
the doc (never reuses ids freed by delete). Cached CSV/PDF reports are
invalidated since the report enumerates speakers.

Returns the auto-allocated `{speaker_id, name}` so the FE can append the
new tab without a re-read.

## Path parameters

- `audio_id` string, required — The unique audio ID.

## Response `200`
