Show HN: Giving Claude Code and codex its voice using kokoro

Developer softcane released Aloud, an open-source macOS tool that reads Claude Code and Codex CLI replies aloud using the local Kokoro text-to-speech engine. The tool runs entirely offline, installs via Homebrew and pipx, and provides hotkeys for full reply playback and stop controls.

Aloud reads Claude Code and Codex replies aloud on macOS. Turn it on with aloud on in any Claude Code or Codex session. Aloud speaks a short summary after each assistant reply. Use Cmd + Ctrl + H for the full reply, or Cmd + Ctrl + . to stop playback. Aloud uses Kokoro https://github.com/hexgrad/kokoro for local text-to-speech. The Python package installs Kokoro. Kokoro downloads its model files the first time speech generation starts, then reuses the local cache. Aloud does not send agent replies to an external TTS service. - macOS. - Python 3.11 or 3.12. Homebrew https://brew.sh .- Claude Code, Codex CLI, or both. brew install python@3.11 pipx pipx ensurepath pipx install --python python3.11 git+https://github.com/softcane/aloud.git aloud install aloud doctor Restart Claude Code or Codex after install. In Codex, open /hooks and trust the Aloud hooks. In macOS System Settings, give Hammerspoon Accessibility permission for the hotkeys. The installer: - creates the Aloud config, cache, log, and session directories; - starts a launchd daemon for speech generation; - installs Hammerspoon hotkeys; - installs Claude Code commands and Codex prompt shortcuts; - merges Aloud hooks into Claude Code and Codex settings; - writes timestamped backups before editing hook settings. Inside Claude Code or Codex: aloud on Aloud arms only that session. Later replies in that session speak a short summary. The agent does not receive aloud on as a prompt. Claude Code also supports /aloud-on and /aloud-off . In Codex, use aloud on and aloud off ; Codex prompt shortcuts are available as /prompts:aloud-on and /prompts:aloud-off after Codex reloads its prompt list. Controls: aloud off : stop speaking this session. Cmd + Ctrl + H : speak the full reply from the last session Aloud spoke. Cmd + Ctrl + . : stop playback. aloud full : speak the full reply from a terminal. aloud stop : stop playback from a terminal. Multiple sessions are tracked separately. If session A speaks, the full-reply hotkey reads session A even if session B finishes later. aloud doctor aloud self-test --no-audio aloud voices aloud voices --play aloud uninstall doctor checks the installed files and hooks. self-test --no-audio checks the registry without using Kokoro or audio hardware. voices --play previews Kokoro voices on the current macOS output device. Aloud writes mutable files under ~/Library : - config: ~/Library/Application Support/Aloud/config.json - socket and session registry: ~/Library/Application Support/Aloud/ - WAV cache: ~/Library/Caches/Aloud/ - daemon log: ~/Library/Logs/Aloud/daemon.log - launchd plist: ~/Library/LaunchAgents/io.aloud.daemon.plist Edit config.json to change voice, speed, or retention settings. launchctl unload ~/Library/LaunchAgents/io.aloud.daemon.plist launchctl load -w ~/Library/LaunchAgents/io.aloud.daemon.plist aloud uninstall pipx uninstall aloud Uninstall removes the launchd plist, Hammerspoon hotkeys, Claude Code commands, Codex prompt shortcuts, and hook entries. It leaves state, cache, and logs in place for inspection. To remove those files too: rm -rf ~/Library/Application\ Support/Aloud ~/Library/Caches/Aloud ~/Library/Logs/Aloud git clone https://github.com/softcane/aloud.git cd aloud python3.11 -m venv .venv .venv/bin/python -m pip install -e '. dev ' .venv/bin/ruff check . .venv/bin/ruff format --check . .venv/bin/pytest .venv/bin/aloud doctor .venv/bin/aloud self-test --no-audio Before release, also run live smoke tests in Claude Code and Codex CLI, then run one real audio smoke on the current macOS output device. Aloud depends on Kokoro https://github.com/hexgrad/kokoro for local speech, espeak-ng https://github.com/espeak-ng/espeak-ng for phonemization, and Hammerspoon https://www.hammerspoon.org for hotkeys.
