## What it does

The skill explains `POST /api/v1/audio/speech`, which turns text into a buffered file or a chunked audio stream. It maps the available TTS models to their voices, output formats, privacy modes, and supported controls, including style prompts, temperature, top-p, speed, and language hints.

It also covers `POST /api/v1/audio/voices` for creating a cloned-voice handle. Requests use a Venice Bearer key or x402, and the body accepts only known fields. The `model` field is mandatory in practice: leaving it out returns `400`, even though the OpenAPI schema lists a default.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add veniceai/skills --skill venice-audio-speech -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-speech/SKILL.md

## When to use it
- turn text into audio with `POST /api/v1/audio/speech`
- match a voice and output format to a TTS model
- stream generated audio in chunks
- create a cloned voice with `POST /api/v1/audio/voices`
- control speech style, speed, and language

## Example prompts
- Use `venice-audio-speech` to prepare a request that saves `tts-xai-v1` output as `hello.mp3`.
- Show how to create a voice clone with `POST /api/v1/audio/voices` and reuse its handle in speech synthesis.
- Inspect `GET /models?type=tts`, then build a request that streams audio with `streaming: true`.

description: Generate speech from text via POST /audio/speech, and clone a voice via POST /audio/voices. Covers TTS models (Kokoro, Qwen 3, xAI, Inworld, Chatterbox, Orpheus, ElevenLabs Turbo, MiniMax, Gemini Flash, Gradium), voices per model, cloned-voice handles and raw ElevenLabs Voice IDs, per-model output formats (model_spec.supported_formats / default_format), streaming, prompt/style control, temperature/top_p, speed clamping, and language hints.

# Venice TTS (`/audio/speech`)

`POST /api/v1/audio/speech` converts text to an audio stream or file. OpenAI-compatible — the OpenAI SDK's `audio.speech.create()` works as a drop-in.

| Method | Path | Auth | Notes |
|---|---|---|---|
| `POST` | `/api/v1/audio/speech` | Bearer key or x402 (SIWX) | JSON body, returns raw audio. Billed per input character. |
| `POST` | `/api/v1/audio/voices` | Bearer key or x402 (SIWX) | `multipart/form-data`. Clone a voice → `vv_…` handle. There is no `GET /audio/voices`. |

## Use when

- You want narration, voice replies, or UI audio from text.
- You need a specific voice family (ElevenLabs, Kokoro, xAI, Qwen 3, Orpheus, Chatterbox, MiniMax, Inworld, Gemini Flash, Gradium).
- You want streaming audio returned as it is generated.
- You need style/emotion control on supported models, or synthesis in a cloned voice.

For music, sound effects and the character-priced ElevenLabs TTS models — v3, v4, v4 Turbo, Multilingual v2 — (async), see [`venice-audio-music`](../venice-audio-music/SKILL.md). For transcription (audio → text), see [`venice-audio-transcription`](../venice-audio-transcription/SKILL.md).

## Minimal request

```bash
curl https://api.venice.ai/api/v1/audio/speech \
  -H "Authorization: Bearer $VENICE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "tts-xai-v1",
    "voice": "eve",
    "input": "Hello, welcome to Venice Voice.",
    "response_format": "mp3",
    "speed": 1.0,
    "streaming": false
  }' --output hello.mp3
```

Response is the raw audio. `Content-Type` is `audio/mpeg`, `audio/opus`, `audio/aac`, `audio/flac`, `audio/wav` or `audio/pcm` depending on the format actually produced.

## Request schema

The body is strict — unknown fields return `400`.

| Field | Type | Default | Notes |
|---|---|---|---|
| `input` | string | — | **Required.** 1–4096 characters, must contain non-whitespace. Text that sanitizes to nothing speakable (e.g. only markup/emoji) → `400 "Input must contain speakable text"`. |
| `model` | string | — | **Send it.** The OpenAPI schema lists a `tts-kokoro` default, but that default is never applied: omitting `model` returns `400 "model is required"`. Unknown id → `404`. |
| `voice` | string, ≤ 512 | the model's default voice | Voices are model-specific; a voice from another model → `400`. Also accepts a cloned-voice handle (`vv_…`) from `POST /audio/voices` (same `model` that created it), and — on models with `supports_custom_voice_id: true` (currently `tts-elevenlabs-turbo-v2-5`) — a raw provider Voice ID. |
