## What you will build

Upload a reference recording, create a named clone and inspect the preview generated during cloning.

## 1. Before you start

Use your own voice or a speaker who explicitly agreed to cloning.

The source file must meet the documented limits: MP3, M4A or WAV, 10 seconds to five minutes, no more than 20MB.

## 2. Try the task

The upload returns `file.file_id`, which refers to the source asset.

Upload the reference recording:

Copy `file.file_id` into the numeric `file_id` below.

## 3. Check the result

Check the API status in the JSON, not only the HTTP status.

### Prepare the payload without copying a fake file ID

After saving the upload result as `upload.json`, this local script creates `clone.json` using the returned file ID.

Use `--data-binary @clone.json` in place of the literal JSON in the cloning call above.

The optional `clone_prompt` uses a separately uploaded short example and its matching transcript.

## 4. Troubleshooting

- An upload ID is not a voice ID; check which stage produced the value you are passing.
- A rejected source file needs a supported format, duration and size before retrying.
- HTTP success alone is insufficient: inspect the API status and any message in the JSON.
- If using optional example audio, verify that its transcript matches the actual recording instead of copying sample text from documentation.

## 5. Try it on your task

Keep the first trial to one source file and one preview sentence.
