claudedo

Voice control for Claude Code on WSL2.

claudedo listens on your mic, runs local speech-to-text, recognizes a wake phrase plus a small command grammar, and injects the matching keystrokes into your active Claude Code tmux session via tmux send-keys. You answer Claude Code's prompts ("yes", "option one", "approve") and dictate prompts by voice — including hands-free while another window (a game) is focused.

It exists because Claude Code's native /voice is hardcoded-blocked in WSL (it assumes WSL has no audio). Modern WSL2 + WSLg does have working mic input via PulseAudio/RDP. claudedo captures the mic itself, transcribes on-device, and drives Claude Code over tmux — fully local, private, backgroundable.

How it works

mic (WSLg/PulseAudio RDPSource)
  -> sounddevice capture
  -> faster-whisper (local STT, on-device)
  -> wake gate: utterance must start with a wake phrase, else DISCARD locally
  -> grammar match (yes/no/one..four/approve/deny/send/type/mode/set/target/cancel)
  -> resolve target session (~/.claude-active)
  -> tmux send-keys -t <session> "<keys>"

Privacy by construction. STT runs on-device. In listen mode, any speech that doesn't start with a wake phrase is dropped the instant it's transcribed — never stored, never sent anywhere. That's what makes always-listening acceptable while you're on voice comms in a game.

Injection is PTY-only. claudedo only ever calls tmux send-keys. It never uses OS-level keyboard input and installs no system-wide keyboard hook. Keystrokes are text into a Linux pseudo-terminal — they work regardless of which window is focused and never touch Windows input or a game/anticheat's view.

Install

git clone <repo> claudedo && cd claudedo
./install.sh

install.sh is idempotent. It installs the WSL audio deps, writes the ~/.asoundrc Pulse shim, verifies the mic path, pip-installs the package, primes the Whisper model, and installs the cc kit (~/.config/claudedo/cc.sh, sourced from every ~/.zshrc/~/.bashrc you have). It also checks the two Windows-side bits it can't automate and tells you to fix them:

• WSLg present (/mnt/wslg/PulseServer). If missing: wsl --update in Windows, then wsl --shutdown, then re-run.
• Mic permission: Windows Settings → Privacy & security → Microphone → enable "Let desktop apps access your microphone". Required.

Verify the riskiest piece (mic capture) first:

claudedo test-audio

Usage

Run it in a terminal you watch — that's the product. You launch claudedo start, it does a quick mic check, then drops into a visible listen loop that prints heard → matched → sent for every utterance. That terminal is your recognition/action console; you attach to the claude-<name> session in another pane to watch the keystrokes land. There is no backgrounding/daemon mode — the whole point is the console you read.

claudedo start            # mic-check, then the visible listen loop (listen mode default)
claudedo start --mode ptt # push-to-talk instead (desk-only — see Modes)
claudedo start --skip-audio-check  # skip the pre-listen mic check
claudedo status           # running? mode? target session?
claudedo stop             # stop a running daemon
claudedo set <name>       # set the sticky target -> claude-<name> (alias: switch)
claudedo unset            # clear the sticky target
claudedo list             # list running claude-* sessions
claudedo test-audio       # verify the mic capture path

Modes

• listen (default) — continuous capture; only acts on utterances that start with a wake phrase; all other speech is transcribed locally and discarded instantly. This is the hands-free path and works while a game is focused, because the trigger is your voice over the mic bridge — not a keyboard hook.
• ptt — push-to-talk. Desk-only: it captures only while the daemon's own terminal window is focused. There is deliberately no global hotkey — a system-wide keyboard hook is the keylogger/cheat silhouette anticheats watch for, and claudedo refuses to install one. For hands-free-while-gaming, use listen mode. (Terminals don't deliver key-up events, so PTT is press-to-start / press-to-stop in the daemon window, not literal hold.)

Switch at runtime by voice: "claudedo mode listen" / "claudedo mode ptt".

Command grammar

Wake phrases (listen mode), fuzzy-matched: "claudedo", "hey claude". "claudedo" is a coined word, so the matcher is lenient (accepts "claude do", "clauddo", "cloud do", …). In PTT mode the wake phrase is optional.

Say	Does
yes / no	answer a yes/no prompt
one / two / three / four	pick numbered option 1–4
approve / deny	allow / deny a permission prompt
send / enter	submit (Enter)
type <phrase>	insert literal text, no submit (read-before-send; say "send")
space [<n>]	insert n spaces (default 1)
backspace [<n>] (alias delete)	delete n chars (default 1), capped at the last submit boundary
erase (alias clear/wipe)	delete everything typed since the last submit/boundary
mode ptt / mode listen	switch input mode
set <name> (alias sticky/switch)	set the sticky target → claude-<name> (persists)
target <name> <command>	one-shot override: run that command on claude-<name> for this utterance only; sticky default unchanged
unset (alias unsticky)	clear the sticky target
list	list running claude-* sessions to the daemon console
cancel / escape	back out of a prompt

Optional filler (select / use / choose) may precede any command and is ignored: select yes and use yes behave like yes. (select 1 is still the select command.)

When no sticky target is set, a bare command auto-targets the only running claude-* session; if several are running it does nothing and asks you to set one.

Number words are normalized to digits before matching ("one"/"won" → 1).

Targeting

~/.claude-active holds the sticky target session name (e.g. claude-rethink-public). The cc kit writes this file when you attach, and claudedo set <name> (alias sticky/switch) overwrites it; unset clears it. A target <name> voice command is a one-shot that does NOT touch the sticky default — it routes a single command and the next bare command reverts to sticky.

Resolution order (one place — target.resolve()): one-shot if present → sticky if set and the session exists → else the only running claude-* session → else (zero or several) do nothing and say so. It never guesses, and never injects into a nonexistent session.

Every name maps to claude-<name> through one helper (target.session_name()), and the cc kit mirrors it exactly — so cc libs (shell) and set libs (voice) refer to the same session claude-libs. The name is your stable, speakable handle: because the kit forces an explicit name (no basename guessing), you always know the exact word to say.

The cc kit lives in ~/.config/claudedo/cc.sh (sourced from your rc; works under bash and zsh). Every command requires an explicit name:

cc <name>    # attach/create claude-<name>; writes ~/.claude-active
ccr <name>   # re-attach an existing claude-<name> only
ccl          # list claude-* sessions
cck <name>   # kill claude-<name>
cckl         # kill all claude-* sessions

The confirmed Claude Code keymap

The keystrokes in keys.py were confirmed empirically against a live claude v2.1.191 session (not assumed):

• Numbered prompts (trust prompt, permission prompt): pressing the bare digit selects and confirms immediately — no trailing Enter.
• Arrow keys move the highlight without acting; Enter then confirms (modeled as an alternative sequence).
• Permission prompt is 1. Yes / 2. Yes, and don't ask again / 3. No; Escape cancels.
• Literal text goes in via send-keys -l (no submit); a bare Enter submits.

If Claude Code changes its prompt UI, re-confirm against a live session and update keys.py — it is the single source of truth.

Config

Everything tunable lives in config.toml: wake phrases, mode + PTT key, Whisper model/language/device, audio segmentation thresholds, and [behavior] (type_autosend, filler_words, auto_target, print_heard). The default model is small; bump to medium if the coined wake word is recognized poorly. claudedo -c <path> ... points at a specific config; otherwise it searches $CLAUDEDO_CONFIG, ~/.config/claudedo/config.toml, then ./config.toml.

• auto_target (default false): with no sticky target set and exactly one claude-* session running, false makes a bare command do nothing and ask you to set one; true auto-targets that single session.
• print_heard (default false, debug): prints non-wake transcripts to the console so you can see how Whisper renders your wake word. Turn it on to debug detection, then off. Whisper has no token for "claudedo" — it commonly emits "claude do" or "claude due", both of which are in the default wake list.

Requirements

Windows 11 + WSL2 (Ubuntu) with WSLg, Python 3.10+, tmux, the claude CLI, and either bash or zsh (the cc kit supports both).
