# Chatterbox · Text to Speech · Multilingual API

> Multilingual Text-zu-Sprooch mat 23 Sproochen, limitéiert op 300 Zeeche pro Ufro

Synthetiséiert Sprooch a ville Sproochen, dorënner Englesch, Franséisch, Däitsch, Spuenesch, Hindi, Arabesch, Chinesesch, Japanesch a Koreanesch. Den Text ass op 300 Zeeche limitéiert. `voice` setzt d'Sprooch, oder eng personaliséiert Audio-URL zesumme mat `custom_audio_language`. `exaggeration` geet vun 0.25 bis 2, an `cfg_scale` kann op 0 gesat ginn, fir beim Sproochtransfer d'Iwwerdroe vum Akzent ze reduzéieren.

## 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 | Text fir d'Sproochsynthes, limitéiert op 300 Zeechen a mat Ënnerstëtzung fir 23 Sproochen. Zu den disponibele Sprooche gehéieren Englesch a Franséisch; Däitsch, Spuenesch, Italienesch a Portugisesch; Hindi an Arabesch; Chinesesch, Japanesch a Koreanesch, ënner anerem. |
| `voice` |  | string | no | `english` |  | Code vun der Sproochsynthes; fir eng personaliséiert Notzung si souwuel eng Audio-URL wéi och eng Auswiel fir custom_audio_language erfuerderlech. |
| `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` | Sproochastellung, déi nëmme gëllt, wann d'Stëmm als personaliséiert URL geliwwert gëtt; soss gëtt se ignoréiert. Gitt d'Sprooch un, déi an deem personaliséierten Audio geschwat gëtt. |
| `exaggeration` |  | number | no | `0.5` | 0.25 – 2 | Ausdrock an emotional Intensitéit vun der Sprooch am Verglach mat der neutraler Astellung vun 0.5. Wann Dir de Wäert erhéicht, gëtt den Ausdrock am Beräich 0.25–2.0 méi staark, och wann extrem Astellunge zu Instabilitéit féiere kënnen. |
| `temperature` |  | number | no | `0.8` | 0.05 – 2 | Passt d'Varietéit vun de Sproochmusteren un, andeems d'Zoufällegkeet vun der Generatioun tëscht 0.05 an 2.0 festgeluecht gëtt; e méi héije Wäert produzéiert méi Variatioun. |
| `cfg_scale` |  | number | no | `0.5` | 0 – 1 | Guidance-Gewiicht vun der Generatioun fir d'Konfiguratioun an d'Geschwindegkeet. Beim Sproochtransfer hëlleft 0.0, d'Iwwerhuele vum Akzent ze begrenzen; de ganze Beräich ass 0.0–1.0. |
| `seed` |  | integer \| null | no |  |  | Seed vun der Generatioun mat zwee Verhalen: 0 wielt eng zoufälleg Generatioun, wärend eng spezifesch Zuel reproduzéierbar Outputs erméiglecht. |

## 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.
