# ElevenLabs TTS Multilingual v2 API

> Meertalige tekst-naar-spraak met stemselectie, instellingen voor stabiliteit, stijl en snelheid en woordtijdstempels

Zet `text` om in spraak met een benoemde `voice` (standaard Rachel). Pas `stability`, `similarity_boost` en `style` aan van 0 tot 1 en `speed` van 0.7 tot 1.2. `previous_text` en `next_text` verbeteren de continuïteit tussen gesplitste passages, `language_code` dwingt een taal af en `timestamps` retourneert timing per woord.

- Model id: `elevenlabs/tts/multilingual-v2`
- Made by: ElevenLabs
- Category: Text to Speech
- Output: audio
- Price: $0.10 / 1000 characters (cheapest run $0.10 (100 API credits))
- Run: `POST https://api.doitong.com/v1/run/elevenlabs/tts/multilingual-v2`
- Quote: `POST https://api.doitong.com/v1/quote/elevenlabs/tts/multilingual-v2`
- Docs page: https://doitong.com/nl/developers/models/elevenlabs/tts/multilingual-v2

## Pricing

Price: **$0.10 / 1000 characters**. Billed per character of `text` (the price is per 1000 characters).

The full example input below costs $0.005 = 5 API credits (50 characters × 100 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/elevenlabs/tts/multilingual-v2` 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 |  | ≥ 1 characters | Tekst die als spraak moet worden gesynthetiseerd. |
| `voice` |  | string | no | `Rachel` |  | Stem die voor spraaksynthese is geselecteerd. |
| `stability` |  | number | no | `0.5` | 0 – 1 | Stabiliteit van de stem, van 0 tot 1. |
| `similarity_boost` |  | number | no | `0.75` | 0 – 1 | Mate van gelijkenisverbetering, van 0 tot 1. |
| `style` |  | number | no | `0` | 0 – 1 | Mate van stilistische overdrijving, van 0 tot 1. |
| `speed` |  | number | no | `1` | 0.7 – 1.2 | Spraaksnelheid ten opzichte van 1.0: lagere instellingen vertragen de voordracht en hogere instellingen versnellen deze. Het bereik is 0.7–1.2, met mogelijke kwaliteitswijzigingen bij extreme instellingen. |
| `timestamps` |  | boolean | no | `false` |  | Bepaalt of gegenereerde spraak tijdstempels per woord bevat. |
| `previous_text` |  | string \| null | no |  |  | Voorafgaande tekst die als continuïteitscontext voor de spraak van de huidige request wordt aangeleverd, om meerdere gegenereerde segmenten vloeiend aan elkaar te koppelen of de continuïteit binnen deze generatie te beïnvloeden. |
| `next_text` |  | string \| null | no |  |  | Volgende tekst die als continuïteitscontext voor de spraak van de huidige request wordt aangeleverd, om meerdere gegenereerde segmenten vloeiend aan elkaar te koppelen of de continuïteit binnen deze generatie te beïnvloeden. |
| `language_code` |  | string \| null | no |  |  | Geef de vereiste mod                    eltaal op met een ISO 639-1-code; de request mislukt met een fout als het model die code niet ondersteunt. |
| `apply_text_normalization` |  | enum (string) | no | `auto` | `auto`, `on`, `off` | Tekstnormalisatiemodus: 'auto' laat het systeem bepalen of normalisatie nodig is, bijvoorbeeld om cijfers als woorden te schrijven. Met 'on' wordt normalisatie altijd toegepast; met 'off' wordt deze uitgeschakeld. |

## 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/elevenlabs/tts/multilingual-v2?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/elevenlabs/tts/multilingual-v2?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/elevenlabs/tts/multilingual-v2", 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": "elevenlabs/tts/multilingual-v2",
      "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.
