# Chatterbox · Text to Speech · Multilingual API

> Flersproget tekst-til-tale med understøttelse af 23 sprog, begrænset til 300 tegn pr. anmodning

Syntetiserer tale på mange sprog, herunder engelsk, fransk, tysk, spansk, hindi, arabisk, kinesisk, japansk og koreansk. Teksten er begrænset til 300 tegn. `voice` angiver sproget eller en brugerdefineret lyd-URL sammen med `custom_audio_language`. `exaggeration` går fra 0.25 til 2, og `cfg_scale` kan sættes til 0 ved sprogoverførsel for at reducere overførsel af accent.

- Price: $0.025 / 1000 characters (cheapest run $0.025 (25 API credits))
- Run: `POST https://api.doitong.ru/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.ru/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 | Tekst til talesyntese, begrænset til 300 tegn og med understøttelse af 23 sprog. Tilgængelige sprog omfatter engelsk og fransk; tysk, spansk, italiensk og portugisisk; hindi og arabisk; kinesisk, japansk og koreansk blandt andre. |
| `voice` |  | string | no | `english` |  | Sprogkode til syntese, hvor brugerdefineret brug kræver både en lyd-URL og et valg for custom_audio_language. |
| `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` | Sprogindstilling, der kun gælder, når stemmen leveres som en brugerdefineret URL; ellers ignoreres den. Angiv sproget, der tales i den brugerdefinerede lyd. |
| `exaggeration` |  | number | no | `0.5` | 0.25 – 2 | Taleudtryk og følelsesmæssig intensitet i forhold til den neutrale indstilling på 0.5. En højere værdi tilføjer udtryksfuldhed inden for området 0.25–2.0, men ekstreme indstillinger kan medføre ustabilitet. |
| `temperature` |  | number | no | `0.8` | 0.05 – 2 | Juster variationen i talemønstre ved at indstille genereringstilfældighed mellem 0.05 og 2.0; en højere værdi giver større variation. |
| `cfg_scale` |  | number | no | `0.5` | 0 – 1 | Genereringsvægt for konfiguration/hastighed. Ved sprogoverførsel hjælper 0.0 med at begrænse overtagelse af accent; hele området er 0.0–1.0. |
| `seed` |  | integer \| null | no |  |  | Genereringsseed med to funktioner: 0 vælger tilfældig generering, mens et bestemt tal gør output reproducerbart. |

## 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.ru/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.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/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.ru/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.ru/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.
