# ElevenLabs TTS Multilingual v2 API

> Synthèse vocale multilingue avec sélection de voix, réglages de stabilité, de style et de vitesse, plus horodatages par mot

Convertit `text` en parole avec une `voice` nommée (Rachel par défaut). Ajustez `stability`, `similarity_boost` et `style` de 0 à 1, et `speed` de 0.7 à 1.2. `previous_text` et `next_text` améliorent la continuité entre les passages divisés, `language_code` impose une langue et `timestamps` renvoie le minutage de chaque mot.

- 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/fr/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 | Texte à synthétiser en parole. |
| `voice` |  | string | no | `Rachel` |  | Voix sélectionnée pour synthétiser la parole. |
| `stability` |  | number | no | `0.5` | 0 – 1 | Stabilité de la voix, de 0 à 1. |
| `similarity_boost` |  | number | no | `0.75` | 0 – 1 | Niveau d'amélioration de la similarité, de 0 à 1. |
| `style` |  | number | no | `0` | 0 – 1 | Degré d'exagération stylistique, de 0 à 1. |
| `speed` |  | number | no | `1` | 0.7 – 1.2 | Vitesse de parole par rapport à 1.0 : les valeurs faibles ralentissent l'interprétation et les valeurs élevées l'accélèrent. La plage est de 0.7–1.2, avec de possibles changements de qualité aux valeurs extrêmes. |
| `timestamps` |  | boolean | no | `false` |  | Contrôle si la parole générée inclut des horodatages pour chaque mot. |
| `previous_text` |  | string \| null | no |  |  | Texte précédent fourni comme contexte de continuité pour la parole de la requête actuelle, soit pour relier harmonieusement plusieurs segments générés, soit pour influencer la continuité au sein de cette génération. |
| `next_text` |  | string \| null | no |  |  | Texte suivant fourni comme contexte de continuité pour la parole de la requête actuelle, soit pour relier harmonieusement plusieurs segments générés, soit pour influencer la continuité au sein de cette génération. |
| `language_code` |  | string \| null | no |  |  | Indiquez la langue requise du modèle avec un code ISO 639-1 ; la requête échoue avec une erreur si le modèle ne prend pas ce code en charge. |
| `apply_text_normalization` |  | enum (string) | no | `auto` | `auto`, `on`, `off` | Mode de normalisation du texte : 'auto' laisse le système décider si une normalisation est nécessaire, par exemple pour écrire les nombres en toutes lettres. La sélection de 'on' applique toujours la normalisation ; la sélection de 'off' la désactive. |

## 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.
