# Chatterbox · Text to Speech · Multilingual API

> 23개 언어를 지원하며 요청당 300자로 제한되는 다국어 텍스트-투-스피치

영어, 프랑스어, 독일어, 스페인어, 힌디어, 아랍어, 중국어, 일본어, 한국어 등을 포함한 여러 언어로 음성을 합성합니다. 텍스트는 300자로 제한됩니다. `voice`로 언어를 설정하거나 `custom_audio_language`와 함께 사용자 지정 오디오 URL을 사용할 수 있습니다. `exaggeration` 범위는 0.25~2이며, `cfg_scale`을 0으로 설정하면 언어 전이를 통해 악센트 전달을 줄일 수 있습니다.

## Pricing

Price: **$0.025 / 1000 characters**. Billed per character of `text` (the price is per 1000 characters).

The full example input below costs $0.002 = 2 API credits (50 characters × 25 API credits / 1000 characters).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/chatterbox/text-to-speech/multilingual` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `text` |  | string | yes |  | ≤ 300 characters | 음성 합성용 텍스트로, 300자 이하이며 23개 언어를 지원합니다. 사용 가능한 언어에는 영어와 프랑스어, 독일어·스페인어·이탈리아어·포르투갈어, 힌디어와 아랍어, 중국어·일본어·한국어 등이 포함됩니다. |
| `voice` |  | string | no | `english` |  | 합성 언어 코드입니다. 사용자 지정으로 사용하려면 오디오 URL과 custom_audio_language 선택 항목이 모두 필요합니다. |
| `custom_audio_language` |  | enum (string) \| null | no |  | `english`, `arabic`, `danish`, `german`, `greek`, `spanish`, `finnish`, `french`, `hebrew`, `hindi`, `italian`, `japanese`, `korean`, `malay`, `dutch`, `norwegian`, `polish`, `portuguese`, `russian`, `swedish`, `swahili`, `turkish`, `chinese` | 음성이 사용자 지정 URL로 제공될 때만 적용되는 언어 설정입니다. 그렇지 않으면 무시됩니다. 해당 사용자 지정 오디오에서 사용되는 언어를 지정하세요. |
| `exaggeration` |  | number | no | `0.5` | 0.25 – 2 | 중립 설정인 0.5를 기준으로 한 음성 표현력과 감정 강도입니다. 값을 높이면 0.25–2.0 범위에서 표현력이 증가하지만, 극단적인 설정은 불안정성을 유발할 수 있습니다. |
| `temperature` |  | number | no | `0.8` | 0.05 – 2 | 생성 무작위성을 0.05~2.0으로 설정해 음성 패턴의 다양성을 조정합니다. 값을 높이면 변형이 늘어납니다. |
| `cfg_scale` |  | number | no | `0.5` | 0 – 1 | 구성 및 속도에 대한 생성 가이던스 가중치입니다. 언어 전환에서는 0.0이 억양 상속을 제한하는 데 도움이 됩니다. 전체 범위는 0.0–1.0입니다. |
| `seed` |  | integer \| null | no |  |  | 두 가지 동작을 지원하는 생성 시드입니다. 0은 무작위 생성을 선택하고, 특정 숫자는 출력을 재현 가능하게 합니다. |

## Example input

Required parameters only:

```json
{
  "text": "Hello from Doitong. This is a short test sentence."
}
```

A fuller example:

```json
{
  "text": "Hello from Doitong. This is a short test sentence."
}
```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.com/v1/run/chatterbox/text-to-speech/multilingual?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "text": "Hello from Doitong. This is a short test sentence."
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/chatterbox/text-to-speech/multilingual?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "text": "Hello from Doitong. This is a short test sentence."
  }),
});
let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "text": "Hello from Doitong. This is a short test sentence.",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/chatterbox/text-to-speech/multilingual", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.com/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "chatterbox/text-to-speech/multilingual",
      "input": {
        "text": "Hello from Doitong. This is a short test sentence."
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
