# Chatterboxhd · Speech to Speech API

> Penukaran suara yang menukar suara klip audio sumber menggunakan suara pratetap atau sampel rujukan

Menukar pertuturan dalam `source_audio_url` kepada suara lain. Pilih satu daripada sembilan suara pratetap dengan `target_voice`, atau berikan sampel sendiri melalui `target_voice_audio_url`, yang mempunyai keutamaan. Jika kedua-duanya tiada, suara dipilih secara automatik. Menetapkan `high_quality_audio` menaikkan skala output kepada 48kHz berbanding 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 yang menunjuk kepada audio sumber untuk penukaran suara. |
| `target_voice` |  | enum (string) | no |  | `Aurora`, `Blade`, `Britney`, `Carl`, `Cliff`, `Richard`, `Rico`, `Siobhan`, `Vicky` | Pilih suara untuk penjanaan pertuturan-ke-pertuturan, atau biarkan target_voice dan target_voice_audio_url tidak ditetapkan supaya suara sasaran dipilih secara rawak. |
| `target_voice_audio_url` |  | string (audio URL) | no |  |  | URL fail audio yang diberi keutamaan berbanding target_voice dalam menentukan suara output. Jika kedua-dua target_voice dan target_voice_audio_url tidak diberikan, suara sasaran lalai digunakan. |
| `high_quality_audio` |  | boolean | no | `false` |  | Pilih output 24kHz dengan False atau audio berkualiti lebih tinggi yang dinaikkan skalanya kepada 48kHz dengan True. Mendayakan peningkatan skala menambah masa penjanaan. |

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.
