# Chatterboxhd · Text to Speech API

> Expresivní převod textu na řeč s přednastavenými hlasy, klonováním ze vzorku bez dalšího učení a volitelným zvukem 48 kHz

Generuje řeč z `text` pomocí přednastaveného `voice` (Aurora, Blade, Britney, Carl, Cliff, Richard, Rico, Siobhan nebo Vicky) nebo klonovaného hlasu z `audio_url`, který má přednost před přednastaveným hlasem. `exaggeration` (0.25 až 2) a `cfg` řídí emoce, `temperature` a `seed` řídí variabilitu. `high_quality_audio` zvýší výstup z 24 kHz na 48 kHz.

## Pricing

Price: **$0.0108 / run**. Price per run: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

The full example input below costs $0.011 = 11 API credits (1 run × $0.01076).

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/resemble-ai/chatterboxhd/text-to-speech` 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

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `text` |  | string | no | `My name is Maximus Decimus Meridius, commander of the Armies of the North, General of the Felix Legions and loyal servant to the true emperor, Marcus Aurelius. Father to a murdered son, husband to a murdered wife. And I will have my vengeance, in this life or the next.` |  | Textový obsah určený k převodu na mluvený zvuk. |
| `voice` |  | enum (string) | no |  | `Aurora`, `Blade`, `Britney`, `Carl`, `Cliff`, `Richard`, `Rico`, `Siobhan`, `Vicky` | Vyberte hlas TTS nebo vynechte voice i zvuk, aby systém jeden náhodně vybral. |
| `audio_url` | `audio` | string (audio URL) | no |  |  | URL vzorku pro klonování hlasu při TTS bez předchozího trénování, která má přednost před nastavením voice. Náhodný výběr hlasu se použije pouze při absenci audio_url i voice. |
| `exaggeration` |  | number | no | `0.5` | 0.25 – 2 | Míra emočního zveličení, obvykle v rozsahu 0.25 až 2.0. |
| `cfg` |  | number | no | `0.5` | 0 – 1 | Síla podmiňování nastavená pomocí classifier-free guidance (CFG). Pro výrazný nebo dramatický projev kombinujte nízké nastavení cfg, například přibližně 0.3, se zveličením přibližně 0.7 nebo vyšším; snížení cfg přibližně na 0.3 může zlepšit také tempo, když referenční hlas mluví rychle. Typické hodnoty jsou 0.2–1.0. |
| `high_quality_audio` |  | boolean | no | `false` |  | Zvolte výstup 24kHz pomocí False nebo kvalitnější zvuk převzorkovaný na 48kHz pomocí True. Povolení převzorkování prodlužuje dobu generování. |
| `seed` |  | integer | no | `0` | ≥ 0 | Seed pro opakovatelné generování zvuku: 0 zvolí seed náhodně, zatímco pevný seed by měl při nezměněných ostatních vlastnostech vytvořit přesně stejný zvukový soubor. |
| `temperature` |  | number | no | `0.8` | 0.05 – 5 | Náhodnost generování, obvykle v rozsahu 0.05 až 5. |

File parameters (`audio`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

```json
{}
```

A fuller example:

```json
{}
```

## 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/resemble-ai/chatterboxhd/text-to-speech?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{}'

# 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/resemble-ai/chatterboxhd/text-to-speech?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({}),
});
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 = {}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/resemble-ai/chatterboxhd/text-to-speech", 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": "resemble-ai/chatterboxhd/text-to-speech",
      "input": {},
      "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.
