## What Is This?

MUSE TTS Embed gives Claude a **persistent audio player** — right in the chat. Everything runs on your machine.

> Looking for direct audio playback without a player widget? See [MUSE TTS Live](https://github.com/falcoschaefer99-eng/muse-tts).

## Features

- **Embedded Player** — play, pause, seek, replay
- **Voice Selector** — switch between 54 voices without leaving the conversation
- **Voice Cloning** — drop a WAV, get a clone (~7s)
- **Speed Control** — 0.5x through 2.0x playback
- **Download** — save any generation as WAV or MP3
- **3 Engines** — Kokoro-82M (~1s), IndexTTS-1.5 (Apple Silicon cloning), Chatterbox (cross-platform cloning)
- **Fully Local** — no cloud APIs, no Docker, no subscription

## Quick Start

### 1. Install dependencies

**macOS (Apple Silicon — fastest):**
```bash
pip install fastmcp mlx_audio
```

**Windows / Linux / Intel Mac:**
```bash
pip install fastmcp kokoro soundfile numpy
```

> On Linux, you also need `espeak-ng`: `sudo apt install espeak-ng`

### 2. Add to Claude Desktop

Open **Settings > Developer > Edit Config** and add:

```json
{
  "mcpServers": {
    "muse-tts-embed": {
      "command": "python3",
      "args": ["/path/to/muse-tts-embed/server.py"]
    }
  }
}
```

Restart Claude Desktop.

### 3. Speak

Ask Claude to speak anything. Try: *"Say hello in a warm voice"* or *"Read this paragraph aloud"*

## Voice Cloning

Add your own reference WAV files to the `voices/` directory. They'll be detected on startup.

```
voices/
  my_narrator.wav
  interview_voice.wav
```

Then ask Claude: *"Speak this using the my_narrator clone"*

Or use `ref_audio` to point to any WAV in `voices/` or `~/Downloads/`:

*"Read this aloud using the reference audio at ~/Downloads/sample.wav"*

## Configuration

| Variable | Default | Description |
|----------|---------|-------------|
| `KOKORO_VOICE` | `am_onyx` | Default voice ID |
| `KOKORO_SPEED` | `1.0` | Default speed (0.5 - 2.0) |
| `MUSE_AUTH_TOKEN` | (required for HTTP) | Bearer token for HTTP mode |
| `MUSE_PORT` | `3001` | HTTP server port |
| `MUSE_HOST` | `127.0.0.1` | HTTP bind address |

## HTTP Mode (Web / Mobile)

For Claude Web or Mobile, run the server in HTTP mode behind a tunnel:

```bash
export MUSE_AUTH_TOKEN=your-secret-token
python3 server.py --http
```

Then expose via tunnel (ngrok, cloudflared) and add the URL to Claude's MCP settings.

> Browsers block auto-play. The player shows a "click to play" hint — tap play to start.

## Voices

54 preset voices across 9 languages (American English, British English, Spanish, French, Hindi, Italian, Japanese, Portuguese, Mandarin).

## Tools

| Tool | What it does |
|------|-------------|
| `muse_speak_embed` | Speak text with embedded player (preset or cloned voice) |
| `muse_embed_check` | Verify engine, platform, and configuration |

## How It Works

Audio is delivered via `structuredContent` — bypasses model context, no size limit. The player is a self-contained HTML/JS app.

## Requirements

- Python 3.10+
- Claude Desktop (latest version with MCP Apps support)
- One of: `mlx_audio` (Mac M-series) or `kokoro` + `soundfile` (any platform)
- ~200MB disk space (model downloads on first use)

<details>
<summary><strong>Troubleshooting</strong></summary>

**Player shows "Generating..." but nothing happens:**
Check that the TTS engine is installed. Run `muse_embed_check` to verify status.

**No sound on Web/Mobile:**
Browsers block auto-play. Click the play button.

**"No TTS engine found":**
See installation above.

**Model download is slow:**
First run downloads ~200MB.

**"Text too long" error:**
Max 2000 characters per generation (~2 minutes of speech). Break longer text into parts.

**Player doesn't appear:**
Update Claude Desktop to the latest version with MCP Apps support.
