## Transcribe Turkish with one request

Set `language` to `tr` 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/gorusme-tr.m4a", "model": "oracle", "language": "tr", "include_diarization": true, "output_format": "json"}'
```

Translate Turkish 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/gorusme-tr.m4a", "model": "oracle_mini", "language": "tr", "translate_to": "en", "output_format": "srt"}'
```

## What to know about Turkish transcription

- Turkish has dotted and dotless i (İ/i and I/ı). Generic lowercasing breaks words; use Turkish-aware case folding (for example `toLocaleLowerCase("tr")`) in search.
- Turkish is agglutinative: one long word can carry several suffixes. Search and keyword spotting work better on stems than on exact words.
- Turkish speakers in Germany and the Netherlands mix in German or Dutch words. Send `tr` when Turkish dominates.

## Where teams use Turkish transcription

- Turkish broadcast, podcast and YouTube subtitles.
- Contact centers in Türkiye and for the Turkish diaspora in Europe.
- Interviews translated to English or German with `translate_to`.

## Choosing a model

Start with `oracle` (US$1.44 per hour) for production Turkish 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 Turkish accuracy figure for this API, so test a sample of your own recordings before committing.

## Questions and answers

### Why does search miss words in my Turkish transcripts?

Usually case folding: "I".toLowerCase() is not "ı". Use Turkish locale rules and stem the words.

### Can I translate Turkish audio to German?

Yes, with an Oracle model and `translate_to: "de"`.

### Which model should I start with?

`oracle` for production audio; `base` for clean, single-speaker recordings.
