# Transcription for legal work

> Produce searchable draft transcripts of depositions, hearings, client interviews and recorded calls, with speakers separated and every word timed so you can cite and check the exact moment.

## A request for a multi-party recording

```json
{
  "audio_url": "<fileUrl from POST /upload>",
  "model": "oracle_max",
  "include_diarization": true,
  "pro_diarization": true,
  "num_speakers": 4,
  "word_timestamps": true,
  "output_format": "json"
}
```

Use `oracle_max` with Pro diarization for rooms with several speakers and crosstalk. For recordings where each party has its own microphone channel, use `channel_speaker_separation` with `channel_labels` instead of diarization.

## How teams use the output

- Search hours of recordings for a name, date or phrase.
- Cite a statement by its timestamp and jump to it in the audio.
- Prepare summaries and exhibits from the draft, then verify against the recording.
- Translate foreign-language recordings with `translate_to` on an Oracle model for a working understanding.

## Limits

A machine transcript is a draft, not a certified court transcript, and translation output is not a sworn translation. Have a qualified person verify any passage you rely on. You are responsible for consent to record and for confidentiality obligations. KolWrite makes no certification claim for this API.

## Questions and answers

### Is the output a certified transcript?

No. It is a machine draft for search and review.

### Can speakers be named instead of "Speaker 1"?

Diarization returns generic labels; map them to names after review. With one speaker per channel, `channel_labels` sets the names directly.

### Can KolWrite transcribe phone recordings?

Yes. For stereo call recordings, channel separation labels each side.
