# Chatterbox · Text to Speech · Multilingual API

> Mehrsprachige Sprachsynthese für 23 Sprachen, begrenzt auf 300 Zeichen pro Anfrage

Synthetisiert Sprache in vielen Sprachen, darunter Englisch, Französisch, Deutsch, Spanisch, Hindi, Arabisch, Chinesisch, Japanisch und Koreanisch. Der Text ist auf 300 Zeichen begrenzt. `voice` legt die Sprache fest, alternativ kann eine benutzerdefinierte Audio-URL zusammen mit `custom_audio_language` verwendet werden. `exaggeration` reicht von 0.25 bis 2, und `cfg_scale` kann für Sprachübertragung auf 0 gesetzt werden, um Akzentübertragung zu verringern.

- Price: $0.025 / 1000 characters (cheapest run $0.025 (25 API credits))
- Run: `POST https://api.doitong.com/v1/run/chatterbox/text-to-speech/multilingual`

## 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 für die Sprachsynthese, begrenzt auf 300 Zeichen und mit Unterstützung für 23 Sprachen. Zu den verfügbaren Sprachen gehören unter anderem Englisch und Französisch; Deutsch, Spanisch, Italienisch und Portugiesisch; Hindi und Arabisch; Chinesisch, Japanisch und Koreanisch. |
| `voice` |  | string | no | `english` |  | Sprachcode für die Synthese; für die benutzerdefinierte Verwendung sind sowohl eine Audio-URL als auch eine Auswahl für custom_audio_language erforderlich. |
| `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` | Spracheinstellung, die nur gilt, wenn die Stimme als benutzerdefinierte URL bereitgestellt wird; andernfalls wird sie ignoriert. Geben Sie die in diesem benutzerdefinierten Audio gesprochene Sprache an. |
| `exaggeration` |  | number | no | `0.5` | 0.25 – 2 | Sprachausdruck und emotionale Intensität relativ zur neutralen Einstellung 0.5. Ein höherer Wert erhöht die Ausdrucksstärke im Bereich von 0.25–2.0, wobei extreme Einstellungen Instabilität verursachen können. |
| `temperature` |  | number | no | `0.8` | 0.05 – 2 | Variieren Sie Sprachmuster, indem Sie die Zufälligkeit der Generierung zwischen 0.05 und 2.0 festlegen; höhere Werte erzeugen mehr Variation. |
| `cfg_scale` |  | number | no | `0.5` | 0 – 1 | Gewicht der Generierungsführung für Konfiguration und Tempo. Bei der Sprachübertragung hilft 0.0, die Übernahme des Akzents zu begrenzen; der vollständige Bereich ist 0.0–1.0. |
| `seed` |  | integer \| null | no |  |  | Generierungs-Seed mit zwei Verhaltensweisen: 0 wählt eine zufällige Generierung, während eine bestimmte Zahl reproduzierbare Ausgaben erzeugt. |

## 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.
