## What you will build

Create a private, persistent voice model and reuse it to produce a short MP3. This suits an agent that needs the same speaker repeatedly, because the reference sample is uploaded once instead of included in each generation request.

## 1. Before you start

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

Listen to the sample, choose a private title and add `--output voice.json` to the creation command.

## 2. Try the task

The creation call makes a voice model.

## 3. Check the result

Keep the returned `_id` and inspect model readiness before synthesis.

### Speak with the saved reference

Save this as `speech.json`, replacing the placeholder with the model's returned `_id` once trained:

Check the request succeeded before playing the file.

An inline-reference clone is a different workflow.

## 4. Troubleshooting

- A rejected reference ID calls for checking the saved model and its state before creating another copy.
- If the wrong voice is heard, distinguish the reference ID from the generation model header.
- If a clip sounds noisy, compare the source recording before adding more generation controls.
- If an MP3 will not open, inspect whether curl saved an API error response instead of audio.

## 5. Try it on your task

Test a plain sentence, a question and a phrase containing numbers.
