# Audio translation

> POST /v1/audio/translations — translate audio in any language to English

**Translate and transcribe to English** an audio file in any language.

## Request

```bash theme={null}
curl https://openp.ai/v1/audio/translations \
  -H "Authorization: Bearer $OPENPAI_API_KEY" \
  -F file=@chinese.mp3 \
  -F model=whisper-1 \
  -F response_format=json
```

### Parameters

Same as [Transcriptions](/en/api-reference/openai/audio-transcriptions), except:

* The output language is **fixed to English** (no `language` field).
* Only `whisper-1` supports this endpoint.

## Response

```json theme={null}
{"text": "Hello, this is a test audio."}
```

## Translating to other languages

To translate audio into a **non-English** language, we recommend:

1. Use `/v1/audio/transcriptions` to first transcribe to the original language's text.
2. Pass the text to `/v1/chat/completions` and have the LLM translate it to the target language.

```python theme={null}
text_zh = client.audio.transcriptions.create(model="whisper-1", file=open("a.mp3","rb")).text

text_ja = client.chat.completions.create(
    model="gpt-5.5",
    messages=[
        {"role": "system", "content": "Translate to Japanese."},
        {"role": "user", "content": text_zh},
    ],
).choices[0].message.content
```

## Billing

Same as transcriptions, charged by audio duration.
