## What it does

The skill documents the `/audio/voice-changer/*` endpoint family in the Venice API. You hand over a recording and get the same delivery back in another voice, with pacing and emotion intact. That matters when dubbing has to line up with picture and re-performing the take is not an option.

The flow runs quote → queue → retrieve → complete. `POST /audio/voice-changer/quote` prices a source of N seconds and needs no key. `/queue` takes either a multipart `file` or a JSON `audio_url` — supply exactly one, since both or neither returns `400`. `/retrieve` returns a status object or the converted audio bytes, and `/complete` releases the provider-held media. Format, length, seed and balance are validated before the charge lands; a voice the provider rejects at queue time gives `400` and the charge is refunded right away.

Here is the catch. The only voice-changer model, `elevenlabs-voice-changer`, is not open to regular API keys yet. It does not appear in `GET /models`, and every endpoint answers `404 "Specified model not found"`. Check that a model carrying `model_spec.voice_changer: true` shows up in `GET /models?type=music` for your key before you bother installing. Billing is per whole minute, so read the tiers from `pricing.durations` instead of assuming a number.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add veniceai/skills --skill venice-audio-voice-changer -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/venice-audio-voice-changer/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/venice-audio-voice-changer/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add veniceai/skills --skill venice-audio-voice-changer -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/venice-audio-voice-changer/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add veniceai/skills --skill venice-audio-voice-changer -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/venice-audio-voice-changer/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install veniceai/skills venice-audio-voice-changer
```

2. **Manually: put the files in place**
- File: `.github/skills/venice-audio-voice-changer/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add veniceai/skills --skill venice-audio-voice-changer -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/veniceai/skills --path skills/venice-audio-voice-changer
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/venice-audio-voice-changer/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add veniceai/skills --skill venice-audio-voice-changer -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/veniceai/skills/tree/HEAD/skills/venice-audio-voice-changer/SKILL.md

## When to use it
- re-record a finished voice-over in another voice
- keep the original timing when dubbing to picture
- price a conversion before uploading the file
- queue a job from a public URL instead of a file
- strip background noise during conversion

## Example prompts
- Convert `take-03.wav` to the Roger voice with the Venice voice changer
- What does a 52-second conversion cost?
- Queue a voice change for `https://example.com/take-03.mp3` with seed 42

description: Async speech-to-speech voice conversion via Venice — re-record a source recording in a different voice while keeping delivery and timing. Covers POST /audio/voice-changer/quote (unauthenticated), /queue (multipart file or JSON audio_url), /retrieve and /complete, how to discover voice-changer models (model_spec.voice_changer on /models?type=music), accepted formats, the source-length cap, whole-minute billing, refunds, and what each endpoint refuses. Note that no voice-changer model is currently open to regular API keys.

# Venice Voice Changer (`/audio/voice-changer/*`)

Speech-to-speech conversion: upload a recording, get the same speech back in a different voice, with the original pacing, emotion and timing preserved. It's asynchronous, with its own quote → queue → retrieve → complete family (parallel to, but separate from, [`venice-audio-music`](../venice-audio-music/SKILL.md)).

> **Availability (checked 2026-09-30):** the endpoints are in the public API spec, but the only voice-changer model, `elevenlabs-voice-changer`, is not yet open to regular API keys. It is not listed by `GET /models`, and regular keys (or no key) get `404 "Specified model not found"` from every endpoint below. Before using this skill, confirm that a model with `model_spec.voice_changer: true` shows up in `GET /models?type=music` for your key; if none does, the feature isn't available to you.

| Method | Path | Auth | Notes |
|---|---|---|---|
| `POST` | `/api/v1/audio/voice-changer/quote` | **None required** (key optional) | Price for a source of N seconds. |
| `POST` | `/api/v1/audio/voice-changer/queue` | Bearer key or x402 (SIWX) | `multipart/form-data` (`file`) **or** JSON (`audio_url`). Charges and enqueues. 40 req/min per user. |
| `POST` | `/api/v1/audio/voice-changer/retrieve` | Bearer key or x402 (SIWX) | Status JSON or the converted audio. 120 req/min per user. |
| `POST` | `/api/v1/audio/voice-changer/complete` | Bearer key or x402 (SIWX) | Release the provider-held media. |

Each endpoint only accepts voice-changer models (`400` otherwise, naming the endpoint to use instead), and `/audio/quote`, `/audio/queue`, `/audio/retrieve`, `/audio/complete` refuse voice-changer models the same way.

## Use when

- You have a real recording (voice-over, dialogue, a take) and want it in another voice without re-performing it.
