Claude Read Aloud

claude-read-aloud

Hear Claude's replies instead of reading them. A speaker button inside
Claude Code's chat box, right-click Read aloud on any highlighted text, a
hotkey, and a settings panel in Claude's own sidebar - voices from free system
TTS up to Speechify / ElevenLabs / OpenAI with your own key.

If you work with Claude Code all day, you read all day - and at some point you
stop absorbing and start skimming. Listening shifts the load from your eyes to
your ears: you take in the whole answer, keep your eyes on the code it
describes, and reply better. And when reading itself is the hard part - low
vision, dyslexia, screen fatigue - it makes Claude Code usable at all.

Free out of the box: system voices with zero setup, or one command installs
[Kokoro], a genuinely good local neural voice - no account, no key, 54 voices.

Two pieces

Install the plugin first (it's the engine), then the extension if you use
VS Code. Terminal-only users need just the plugin.

Install

claude plugin marketplace add michaelpgifford/claude-read-aloud
claude plugin install read-aloud@claude-read-aloud

(Same two steps work inside Claude Code as /plugin marketplace add … and
/plugin install …, or from a local clone by passing its path to
marketplace add.)

Requires Python 3.9+ on your PATH (python3, or python on Windows).
No packages to install - the whole engine is one standard-library script.

Use

On Linux, run /read-aloud:voice-setup first. macOS and Windows system
voices are decent out of the box; Linux's stock voice is espeak, which is not.
One command and ~340MB later you have a genuinely pleasant local voice, free
forever - the plugin will remind you once if you skip this.

(Type /speak and let completion fill the namespace - commands are listed
under their plugin name.)

Long replies start speaking in ~1-3 seconds regardless of length: text is
split at sentence boundaries into ramped chunks (small first - its size is
the time-to-first-sound), and each next chunk synthesises while the previous
one plays, so there are no gaps.

Voices

Config lives at ~/.config/claude-read-aloud/config.json
(%APPDATA%\claude-read-aloud\config.json on Windows):

{
  "provider": "speechify",
  "voice": "oliver",
  "speed": 1.0,
  "auto_read": false
}

voice is the provider's own voice name/id (macOS: say -v '?' lists yours;
cloud providers list voices in their consoles). API keys go in environment
variables, never in the file.

A local neural engine plugs in through command - {text} is replaced with
the text to speak; add {out} if your engine writes a WAV for the plugin to
play (that's what enables gapless chunking):

{
  "provider": "command",
  "command": "piper -m /path/to/voice.onnx -f {out}"
}

The fine print that saves you a support ticket

• Auto-read is off by default, on purpose. A working session produces hours
  of speech per day (we measured 4+). Try /speak-auto on - most people come
  back to on-demand within a day, and that's the intended workflow.
• Replies cap at 12,000 characters (~14 minutes) and say so when cut.
  Code blocks are spoken as "code omitted" - nobody wants JSON read aloud.
• Stop always works mid-sentence: /speak-stop, or the button/hotkey below.
• Speechify's WAV arrives with broken (streaming) header sizes; the plugin
  repairs them - if you ever hear a burst of static with another tool, that's
  what it was.

Buttons and hotkeys in VS Code

The companion extension adds, safely and update-proof:

• a status-bar Read aloud button (bottom-left, under the chat input),
• a toolbar icon on the Claude Code panel,
• Ctrl+Alt+S / Ctrl+Alt+X (⌘⌥S / ⌘⌥X on macOS),
• the settings panel, voice picker, right-click menu, and in-chat button below.

Install it from the VS Code Marketplace - search "Claude Read Aloud", or:

code --install-extension MichaelGifford.claude-read-aloud-button

It auto-detects the installed plugin. (From source instead: clone this repo,
npx @vscode/vsce package in vscode-extension/, and install the .vsix
via Extensions → … → Install from VSIX.)

The status-bar button sits bottom-left, directly under the chat input, and the
toolbar icon rides on the Claude Code panel itself:

The good stuff: in-chat button + right-click "Read aloud"

The two triggers that actually feel native - and, in daily use, the ones you
end up reaching for:

• A speaker button inside the chat box, right next to the mic. Click it and
  it reads the reply you're looking at - the visible conversation in that pane,
  never another tab's and never a transcript from somewhere else. Highlight
  text first and it reads that, cutting off whatever was playing: a new
  reading always replaces the old, because two at once are unlistenable.
• Highlight any text in the chat → right-click → "Read aloud" in the same
  menu as copy/paste.

The speaker sits right where your eyes already are, next to the mic:

Highlight, right-click, and it's in the same menu as copy and paste:

The extension offers this once on startup (a small toast); or run
"Claude Read Aloud: Install in-chat button" from the Command Palette,
confirm, reload. Undo any time with "Remove in-chat button".

Settings panel and voice picker

A Read Aloud section lives inside Claude Code's own sidebar: current voice
with test, provider switcher, speed, auto-read, and the in-chat button toggle.
Change voice… opens a searchable picker of the current provider's voices -
selecting one saves it and plays a sample in that voice immediately.

Read this part before enabling it. VS Code offers no way to put a button
inside another extension's webview, so this works by patching two files of
the installed Claude Code extension on your machine:

• webview/index.js gets a script appended (never spliced - an upstream
  change can stop it matching, but can't corrupt the bundle) that inserts the
  button and captures right-click selections.
• extension.js's Content-Security-Policy gains one directive,
  connect-src http://127.0.0.1:48777, so the button can reach this
  extension's local server. That is a real, if small, widening of the webview
  sandbox - one localhost port - and it's the entire reason this is opt-in
  rather than default.

Originals are backed up beside each file (*.cra-orig) and restored exactly on
removal. Every Claude Code update wipes the patch; the extension notices on
startup and re-applies it, asking you to reload. Worst case, the button
disappears until the next reload - the hotkeys and status-bar button never
depend on it. If you previously hand-patched these files with something else,
revert that first; the patcher refuses to stack two injections.

This is a userscript-style local mod, in the same spirit as browser extensions
that add buttons to websites. It never leaves your machine. The right fix is
Anthropic shipping a TTS affordance natively - if you want that, add your
voice to a feature request on
anthropics/claude-code.

How it decides what to read

• /speak and auto-read use the session's own transcript (hooks receive the
  exact path - never a guess).
• The VS Code button scopes to the window's workspace, so a busier session in
  another project can't hijack what gets read.
