Talk with Claude out loud on your Mac.
Natural turn-taking · on-device speech recognition · no audio leaves your computer

[npm version] [npm downloads] [Tests] [Security] [CodeQL]

[Platform: macOS, Apple Silicon] [MCP server] [Node.js 22+] [License: MIT] [Dependabot enabled] [Vibe-coded with Claude]

Claude speaks through your Mac's speakers, listens to your answer the way a person would, and gets back what you said as text. Speech recognition runs on your Mac, so no audio leaves your computer.

Claude ──speak_and_listen("Tests pass. Open the PR?")──▶  🔊 "Tests pass. Open the PR?"                                                         🎙 you: "yes, and tag Priya"Claude ◀──────────────── "Yes, and tag Priya." ─────────  whisper.cpp on your Mac

Perfect for:

  • Long tasks: Claude works quietly and checks in out loud when it needs a decision, so you can step away from the screen.
  • Quick reviews: a 20-second summary of a pull request, then "approve it?"
  • Resting your eyes, or your wrists, after a long day at the keyboard.
  • Thinking out loud: talking a problem through instead of typing it.

Features

  • 🔒 On-device. whisper.cpp transcribes on your Mac. Recordings are deleted after each turn.
  • 📞 Calls. Run /mac-voice-mcp:call and the mic stays open until you hang up: talk whenever you like, while Claude works or waits. With headphones you can talk over Claude, and an optional floating bubble shows the call with mute and hang up (more).
  • 💬 Natural turn-taking. A soft chime, then it waits for you to start, and hands back about 1.5 seconds after you stop. No push-to-talk.
  • ⚡ Fast replies. A warm whisper.cpp server keeps the model loaded, so transcribing takes a fraction of a second on Apple Silicon.
  • 🗣️ A natural voice, if you want one. Uses your best macOS voice, or the optional Kokoro neural voice.
  • ✋ Asks before installing anything. Setup checks what you already have and reuses it.
  • 🙋 Talk while Claude works. Say "Claude, use the other branch" mid-task and it takes it into account at its next step (Claude Code plugin).
  • 🫧 Voice Buddy (optional, Claude Code). A one-line status above the prompt shows when Claude is speaking or listening, your first keystroke interrupts it, and on a call it hands your words to Claude while it waits.
  • 🪟 One mic, many windows. Claude Code, Claude Desktop and Cursor take turns instead of talking over each other.
  • 📏 Measured, not guessed. doctor checks the whole pipeline on your Mac and scores it PASS, WARN or FAIL.

Quick start

You need a Mac (Apple Silicon recommended) and Node.js 22 or newer.

1. Install.

  • Claude Code (recommended). Install the plugin, and Voice Buddy with it:

    /plugin marketplace add jeet0007/mac-voice-mcp/plugin install mac-voice-mcp@mac-voice-mcp/plugin install voice-buddy@mac-voice-mcp

    Voice Buddy is optional: it adds a one-line voice status above the prompt and lets you interrupt by typing (more).

  • Cursor or VS Code: [Add to Cursor] [Install in VS Code]

  • Claude Desktop and other apps: add npx -y mac-voice-mcp@latest as a stdio MCP server. See Install for each app.

2. Set up. Ask Claude to "set up voice" (or run /mac-voice-mcp:setup). It checks for SoX, whisper.cpp and a speech model, shows you what's missing, and installs it only after you say yes.

3. Allow the microphone. The first time Claude listens, macOS asks. Click Allow.

4. Talk. Run /mac-voice-mcp:talk fix the flaky login test, or ask Claude to "check in with me by voice when you need a decision". Reply after the chime. Or start a call with /mac-voice-mcp:call and talk like on the phone; say "hang up" to end it.

Allow voice turns without prompts

Claude Code asks for approval every time Claude wants to speak, which breaks the flow of a conversation. To allow voice turns, add the tool to permissions.allow in ~/.claude/settings.json:

json
{  "permissions": {    "allow": [      "mcp__plugin_mac-voice-mcp_voice-mcp__speak_and_listen",      "mcp__voice-mcp__speak_and_listen"    ]  }}

The first name is for the plugin, the second for claude mcp add voice-mcp …. Leave voice_setup out, so installs still ask you first.

How it works

The server has two tools and two prompts:

What it does
speak_and_listenSpeaks a short message, listens for one conversational turn and returns the transcript.
voice_setupChecks what's installed. After you agree, it installs only what's missing.
setup promptA guided setup: it checks, asks you, installs, then runs a spoken test.
voice_mode promptA hands-free session where Claude checks in by voice at natural points.

Claude is told to write for the ear: short sentences, no markdown, file names instead of paths. Anything that slips through is rewritten before it's spoken. In Claude Code, the plugin keeps a voice conversation in voice until you type. More in Using it.

Troubleshooting

Run npx -y mac-voice-mcp@latest doctor first. It tests setup, the voice and transcription, and your speakers and mic, and tells you which part fails.

SymptomFix

🤖 Vibe-coded

This project was designed and written with Claude, in conversation. A human (me) steered it, tested it on a real Mac and checked the test suite, but most of the code was written by AI. Read the Disclaimer before you rely on it.

Disclaimer

mac-voice-mcp is a free, open-source personal project. It's provided as is, with no warranty of any kind, and the authors aren't liable for any damage or loss from using it. See the LICENSE for the exact terms. In plain words:

  • It turns on your microphone whenever an AI assistant calls speak_and_listen, and for the whole of a call, until you hang up. It plays sound through your speakers.
  • Speech recognition makes mistakes. An assistant may act on a misheard word. Check what it heard before you let it do anything you can't undo, like deleting files, pushing code or sending messages.
  • It installs software on your Mac, but only after you agree: Homebrew packages, and kokoro-js with npm if you choose the Kokoro voice. Those are separate projects, under their own licenses (below).
  • There's no guaranteed support. Issues and pull requests are welcome, and fixed on a best-effort basis.

speak_and_listen

Speak and listen

Say something out loud to the user and hear their spoken reply. Speaks text_to_speak through the computer's speakers, then listens like a conversation turn — it waits for the user to start talking and stops when they finish — and returns an on-device transcript of what they said. Write text_to_speak for the ear, not the screen: - 1–3 short sentences, under ~40 words; lead with the outcome, then one question. - Plain words only: no markdown, bullets, emoji, code, file paths, URLs, stack traces or tables. - Describe code instead of reading it ("I added a retry to the upload function"), say file names not paths ("in index.ts"), round numbers ("about two hundred ms"), spell out symbols. - Ask one question at a time, answerable in a few words ("Should I deploy it — yes or no?"). - Put the details (diffs, logs, links) in your normal on-screen reply, and say so out loud. - Tool output (Bash stdout, file writes) is NOT the on-screen reply. Only your own assistant message text renders. - A spoken turn with no assistant message text shows the user nothing — never skip the on-screen reply. Good: "The build passed and all tests are green. Want me to open the pull request?" Bad: "## Results\n- `npm test` ✅ 42/42\n- see /Users/x/repo/src/index.ts:120" Once the user is talking with you by voice, keep the conversation in voice: answer each transcript with another speak_and_listen call (not a text reply) until they say stop or start typing. To end voice mode, or for a one-way announcement, pass listen: false: it returns at once and speaks while you work. A reply of "(No speech detected …)" means the user did not answer — never treat it as consent. Ask once more; if still nothing, stop and say on screen that voice mode is paused and they can type to carry on (not speak: the mic is off). The "voice-mcp timing" line at the end is diagnostics: ignore it unless the user asks why things feel slow. If it reports that voice-mcp is not set up, call voice_setup.

call

Call

Start or end a call: a hands-free session where the microphone stays open and the user talks whenever they like, like a phone call, until they hang up. action start takes the speaker and microphone, says a short greeting and returns the rules of the call; action end hangs up (also happens when the user says "hang up" or "bye Claude", or after a long silence). During the call, speak with say and hear the user with listen.

输入参数action必填

say

Say (on a call)

During a call: say text out loud and return at once, so you carry on working while it plays. The result includes anything the user said meanwhile. Only during a call: use speak_and_listen otherwise. Write text for the ear, not the screen: - 1–3 short sentences, under ~40 words; lead with the outcome, then one question. - Plain words only: no markdown, bullets, emoji, code, file paths, URLs, stack traces or tables. - Describe code instead of reading it ("I added a retry to the upload function"), say file names not paths ("in index.ts"), round numbers ("about two hundred ms"), spell out symbols. - Ask one question at a time, answerable in a few words ("Should I deploy it — yes or no?"). - Put the details (diffs, logs, links) in your normal on-screen reply, and say so out loud. - Tool output (Bash stdout, file writes) is NOT the on-screen reply. Only your own assistant message text renders. - A spoken turn with no assistant message text shows the user nothing — never skip the on-screen reply.

输入参数text必填

listen

Listen (on a call)

During a call: return what the user has said since you last heard from them, at once if something is waiting, otherwise wait up to wait_seconds (default and maximum 40) for their next words. "(still on the call, nothing said)" means nobody spoke yet: call listen again to keep waiting, or say something. Once it reports that the call ended, don't call it again.

输入参数wait_seconds

voice_setup

Voice setup

Check whether this computer has everything speak_and_listen needs — text-to-speech, a microphone recorder (SoX), whisper.cpp speech-to-text and the speech model — and optionally install what's missing. Anything already installed is reused (an existing model elsewhere on disk is symlinked, not re-downloaded). Call it with install=false (the default) first and tell the user what is missing. Only call it with install=true after the user agrees: it runs `brew install` for the missing packages and downloads the speech model once. It never uninstalls or changes anything else. kokoro=true (also only after the user agrees) installs the optional Kokoro voice: more natural than the built-in one, runs on this Mac, about 1 GB on disk. Once installed it's used automatically; the built-in voice stays as the fallback. bubble=true (also only after the user agrees) builds the floating call bubble on this Mac with swiftc: a small window during calls with mute and hang up. If it reports INSTALLING, the install continues in the background — wait a minute and call it again to check.
