## Transcribe Dutch with one request

Set `language` to `nl` and start a job. Poll `GET /transcribe/{jobId}` for the result, or pass a `webhook_url`.

```bash
curl https://app.kolwrite.com/transcribe \
  -H "x-api-key: $KOLWRITE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"audio_url": "https://example.com/vergadering-nl.m4a", "model": "oracle", "language": "nl", "include_diarization": true, "output_format": "json"}'
```

Translate Dutch audio into English in the same job (Oracle models only):

```bash
curl https://app.kolwrite.com/transcribe \
  -H "x-api-key: $KOLWRITE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"audio_url": "https://example.com/vergadering-nl.m4a", "model": "oracle_mini", "language": "nl", "translate_to": "en", "output_format": "srt"}'
```

## What to know about Dutch transcription

- One code, `nl`, covers the Netherlands, Flanders and Suriname. Flemish pronunciation and vocabulary differ; test Belgian recordings.
- Dutch writes compounds as one word. Split or join compounds consistently before comparing with a reference.
- Dutch business speech is full of English terms. Send `nl` explicitly on mixed recordings.

## Where teams use Dutch transcription

- Meeting minutes and council recordings in the Netherlands and Belgium.
- Dutch podcasts and video subtitles.
- Customer interviews translated with `translate_to: "en"`.

## Choosing a model

Start with `oracle` (US$1.44 per hour) for production Dutch audio. Use `base` (US$0.48) for clean, single-speaker recordings at volume, `oracle_mini` (US$0.96) for the cheapest translation, and `oracle_pro` or `oracle_max` for noisy or difficult audio. KolWrite does not publish a Dutch accuracy figure for this API, so test a sample of your own recordings before committing. Full comparison: [models and prices](https://console.kolwrite.com/models).
