Is the Speak TTS skill free?

Yes. The skill itself is free from EmZod/speak. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Speak TTS SkillProof Score?

6.8/10 — installs cleanly 3/5, triggers reliably 5/5, output vs. baseline 6/10, docs & honesty 3/5.

How do I install Speak TTS?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Speak TTS with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 6.8/10
Tested: Jul 16, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 50bdfbb

Code-audited rather than executed (no Bun runtime and no throwaway 500MB model download in this sandbox): every documented flag, command, and even exact error string ('Server not running', file-not-found, sox-missing) was found genuinely implemented across a real 2,827-line TypeScript + 752-line Python codebase, not vaporware. But SKILL.md's own Prerequisites table never mentions Bun or Python 3.10+, and the project's own recommended agent quick-setup (copy SKILL.md only) ships a skill that references a `speak` binary that isn't actually on PATH.

What Speak TTS does

Gives an agent a local `speak` CLI (Bun + Python/MLX Chatterbox backend) to read text, Markdown, or piped content aloud, clone a voice from a short sample, batch-process chapters, and resume interrupted long-document generation, entirely on-device with no API keys. Triggers on requests to read something aloud, narrate an audiobook, or give a spoken response, but only functions on Apple Silicon Macs.

How to install Speak TTS

git clone https://github.com/EmZod/speak.git
mkdir -p ~/.claude/skills
cp -r speak ~/.claude/skills/speak-tts
cd ~/.claude/skills/speak-tts && bun install && alias speak="bun run $(pwd)/src/index.ts"

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Speak TTS

Narrate this long ebook chapter and let it resume if interrupted.
Turn this markdown doc into spoken audio without any cloud API keys.
