## What it does

The skill drives `scripts/elevenlabs_tts.py`, which talks to the ElevenLabs API and writes an mp3. Pick a voice by preset name (`rachel`, `adam`, `bella`, `elli`, `josh`, `arnold`, `ava`) or pass a raw voice ID. `rachel` is the default, and the model is `eleven_monolingual_v1` unless you override it.

Two parameters shape the delivery. `stability` (0.0–1.0, default 0.5) — lower values give more expressive variation, higher values keep it consistent. `similarity_boost` (0.0–1.0, default 0.75) holds the output closer to the original voice characteristics. Output path goes through `--output`, and directories are created for you.

You need a working `ELEVENLABS_API_KEY` in `.env` before the first run, otherwise the script has nothing to authenticate with. It also imports as a module: `generate_speech(text=..., voice_id=...)` returns the absolute path to the finished file.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add glebis/claude-skills --skill elevenlabs-tts -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add glebis/claude-skills --skill elevenlabs-tts -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add glebis/claude-skills --skill elevenlabs-tts -a cursor
```

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

### GitHub Copilot

## When to use it
- turn a block of text into an mp3 file
- narrate a video with a chosen voice
- tune delivery with stability and similarity boost
- list the available voices
- call speech generation from your own Python code

## Example prompts
- Narrate this text with the adam voice and save it to audio/narration.mp3
- Generate audio from this text with stability 0.7
- List the available voices

description: This skill converts text to high-quality audio files using ElevenLabs API. Use this skill when users request text-to-speech generation, audio narration, or voice synthesis with customizable voice parameters (stability, similarity boost) and voice presets (rachel, adam, bella, elli, josh, arnold, ava).

# ElevenLabs Text-to-Speech

## Overview

Generate professional audio files from text using ElevenLabs' advanced text-to-speech API. The skill provides pre-configured voice presets with sensible defaults, voice parameter customization, and direct access to the `scripts/elevenlabs_tts.py` script for programmatic control.

## Quick Start

To generate audio from text:

1. Ensure the `.env` file contains a valid `ELEVENLABS_API_KEY`
2. Execute the script with text: `python scripts/elevenlabs_tts.py "Your text here"`
3. Specify voice and output: `python scripts/elevenlabs_tts.py "Text" --voice adam --output audio/output.mp3`

## Voice Presets

Seven pre-configured voices are available. See `references/api_reference.md` for complete voice descriptions:

- `rachel` (default) - Clear, professional female
- `adam` - Deep, authoritative male
- `bella` - Warm, friendly female
- `elli` - Young, enthusiastic female
- `josh` - Friendly, conversational male
- `arnold` - Deep, powerful male
- `ava` - Expressive, dynamic female

## Parameters

### Text
The text to convert to speech. Any length is supported.

### Voice Selection
Specify voice using preset name (e.g., `rachel`, `adam`) or direct ElevenLabs voice ID.

### Voice Parameters
- **stability** (0.0-1.0, default 0.5): Lower values create expressive variation; higher values ensure consistency
- **similarity_boost** (0.0-1.0, default 0.75): Higher values maintain closer adherence to voice characteristics

### Output
Specify the output file path. Default is `output.mp3`. Directories are created automatically.

## Usage Examples

### Basic Python Usage
```python
from scripts.elevenlabs_tts import generate_speech

path = generate_speech(
    text="Hello, this is a test message",
    voice_id="rachel"
)
```

### Command Line
```bash
# With default voice
python scripts/elevenlabs_tts.py "Generate this text"

# With custom voice and stability
python scripts/elevenlabs_tts.py "Different voice" --voice adam --stability 0.7

# To custom output path
python scripts/elevenlabs_tts.py "Save here" --output audio/narration.mp3

# List available voices
python scripts/elevenlabs_tts.py "" --list-voices
```

## Implementation Notes

- The script handles API communication with error reporting
- Output directories are created automatically if they don't exist
- Returns absolute path to generated audio file
- Uses `eleven_monolingual_v1` model by default (can be overridden)

## Resources

- `scripts/elevenlabs_tts.py` - Main Python script for text-to-speech generation. Can be imported as a module or executed from command line.
