# Chatterboxhd · Speech to Speech API

> Pretvorba glasa koja ponovno izgovara izvorni audioisječak unaprijed postavljenim glasom ili referentnim uzorkom

Pretvara govor u `source_audio_url` u drugi glas. Odaberite jedan od devet unaprijed postavljenih glasova s pomoću `target_voice` ili navedite vlastiti uzorak putem `target_voice_audio_url`, koji ima prednost. Ako nijedan nije naveden, glas se odabire automatski. Postavljanje `high_quality_audio` povećava kvalitetu izlaza na 48kHz umjesto 24kHz.

- Output: audio
- Price per minute of your input audio: $0.02 / minute of input audio (cheapest run $0.02 (20 API credits))
- Run: `POST https://api.doitong.ru/v1/run/resemble-ai/chatterboxhd/speech-to-speech`
- Quote: `POST https://api.doitong.ru/v1/quote/resemble-ai/chatterboxhd/speech-to-speech`

## Pricing

Price: **$0.02 / minute of input audio**. Price per minute of your input audio: 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 $0.02 = 20 API credits (1 min input audio × $0.02).

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/speech-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

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `source_audio_url` |  | string (audio URL) | yes |  |  | URL izvornog audija za pretvorbu glasa. |
| `target_voice` |  | enum (string) | no |  | `Aurora`, `Blade`, `Britney`, `Carl`, `Cliff`, `Richard`, `Rico`, `Siobhan`, `Vicky` | Odaberite glas za generiranje speech-to-speech ili izostavite i target_voice i target_voice_audio_url kako bi se ciljni glas odabrao nasumično. |
| `target_voice_audio_url` |  | string (audio URL) | no |  |  | URL audio datoteke koji ima prednost pred target_voice pri određivanju izlaznog glasa. Ako nisu zadani ni target_voice ni target_voice_audio_url, koristi se zadani ciljni glas. |
| `high_quality_audio` |  | boolean | no | `false` |  | Odaberite izlaz od 24kHz uz False ili audio više kvalitete povećan na 48kHz uz True. Uključivanje povećanja razlučivosti produljuje vrijeme generiranja. |

File parameters (`source_audio_url`, `target_voice_audio_url`) 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
{
  "source_audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

A fuller example:

```json
{
  "source_audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

## 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/speech-to-speech?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "source_audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
  }'

# 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/speech-to-speech?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "source_audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
  }),
});
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 = {
    "source_audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/resemble-ai/chatterboxhd/speech-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/speech-to-speech",
      "input": {
        "source_audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
      },
      "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.
