## About

# Speekify

Speekify turns text into a local WAV file you can listen to — from inline CLI
text, stdin, local `.txt`/`.md`/`.pdf` files, YouTube transcripts, or the
readable content of a URL. Audio is generated locally with Supertonic v3.

## Features

| Capability | What you get |
|---|---|
| **Many input sources** | Inline text, piped stdin, local `.txt`/`.md`/`.pdf` files, readable URLs, and YouTube transcripts — auto-detected. |
| **Local TTS** | WAV files synthesized on your machine with Supertonic v3 — no audio leaves your computer. |
| **Multilingual** | `en`, `fr`, `de`, `es`, `it`, `pt`, `ja`, `ko`, and more, plus `na` for language-agnostic synthesis. |
| **Auto-translation** | By default Speekify auto-detects the source language and synthesizes in it — no translation. English is detected and translated to French before TTS only when you pass `--lang fr`. |
| **Voice control** | 10 built-in voices (`M1`–`M5`, `F1`–`F5`), custom Voice Builder JSON styles, plus speed and synthesis-step tuning. |
| **MCP server** | Expose Speekify as a tool so AI assistants can generate audio during automations. |

## Install

`speekify setup` (run once after installing) downloads and warms the Supertonic
model and, by default, the English→French translation model. If you skip it, the
models download automatically on first use.

### macOS — no Python or uv required

Once a release is published, install the standalone binary via Homebrew:

```bash
brew tap otterlyspacelabs/speekify https://github.com/OtterlySpaceLabs/speekify
brew install speekify
speekify setup
```

Or download the archive directly:

```bash
curl -L -o speekify.tar.gz https://github.com/OtterlySpaceLabs/speekify/releases/latest/download/speekify-macos-arm64.tar.gz
tar -xzf speekify.tar.gz
mv speekify /usr/local/bin/speekify
speekify setup
```

### With pip / pipx / uv

Once released on PyPI:

```bash
pip install speekify        # or: pipx install speekify  (recommended for CLIs)
speekify setup

uv tool install speekify    # uv users
speekify setup
```

Run without installing:

```bash
uvx speekify "Hello world"
pipx run speekify "Hello world"
```

### From source with uv

```bash
uv sync
uv run speekify setup
```

## Quick start

Speekify is a CLI. Give it inline text, a URL, a local file path, or piped
stdin:

```bash
speekify "Hello world"                                        # inline text
speekify https://example.com/article                          # readable URL
speekify ~/Documents/article.pdf                              # local PDF
speekify --lang fr "https://www.youtube.com/watch?v=eSP7PLTXNy8"   # YouTube
printf 'Hello from stdin' | speekify                          # stdin
speekify --voice F2 --output-dir ~/Desktop "Hello world"      # pick voice + dir
```

Wrap URLs in quotes when they contain `?` or `&` (common with YouTube), or the
shell may reject the command. From a source checkout, prefix any command with
`uv run` (e.g. `uv run speekify "Hello world"`).

## MCP automation server

Speekify ships a local Model Context Protocol (MCP) server so AI assistants can
call it as a tool. It exposes `speekify_generate_wav` (text/URL/file → WAV with
structured details), `speekify_generation_defaults` (supported voices, languages,
and ranges), and a `news_recap_to_audio` prompt template.

```bash
speekify mcp                              # stdio transport for desktop AI clients
speekify mcp --transport streamable-http  # HTTP endpoint for local experiments
```

Per-client setup (Claude Code, GitHub Copilot, Codex, OpenAI remote MCP):
