# Chatterboxhd · Speech to Speech API

> 프리셋 음성 또는 참조 샘플로 소스 오디오의 음성을 바꾸는 음성 변환

`source_audio_url`의 음성을 다른 음성으로 변환합니다. `target_voice`로 9개의 프리셋 음성 중 하나를 선택하거나 `target_voice_audio_url`로 직접 샘플을 제공할 수 있으며, 직접 제공한 샘플이 우선합니다. 둘 다 없으면 음성이 자동으로 선택됩니다. `high_quality_audio`를 설정하면 출력이 24kHz 대신 48kHz로 업스케일됩니다.

- Model id: `resemble-ai/chatterboxhd/speech-to-speech`
- Made by: Resemble AI
- Category: Text to Speech
- 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`
- Docs page: https://doitong.com/ko/developers/models/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 |  |  | 음성 변환에 사용할 원본 오디오를 가리키는 URL입니다. |
| `target_voice` |  | enum (string) | no |  | `Aurora`, `Blade`, `Britney`, `Carl`, `Cliff`, `Richard`, `Rico`, `Siobhan`, `Vicky` | 음성-음성 생성에 사용할 음성을 선택합니다. 또는 target_voice와 target_voice_audio_url을 모두 지정하지 않으면 대상 음성을 무작위로 선택합니다. |
| `target_voice_audio_url` |  | string (audio URL) | no |  |  | 출력 음성을 결정할 때 target_voice보다 우선하는 오디오 파일 URL입니다. target_voice와 target_voice_audio_url을 모두 제공하지 않으면 기본 대상 음성을 사용합니다. |
| `high_quality_audio` |  | boolean | no | `false` |  | False는 24kHz 출력을, True는 48kHz로 업스케일된 고품질 오디오를 선택합니다. 업스케일링을 활성화하면 생성 시간이 늘어납니다. |

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.
