punt-vox 1.10.0

Text-to-speech CLI, MCP server, and Claude Code plugin (ElevenLabs, AWS Polly, OpenAI)

punt-vox

Voice for your AI coding assistant.

When Claude Code finishes a task, hits an error, or needs your approval --- you hear it. No need to watch the terminal. Keep working; your assistant will tell you what happened.

Platforms: macOS, Linux

Hear It

Real samples generated by vox with ElevenLabs v3. The first three are the same recap with different /vibe moods --- expressive tags change how the voice sounds without changing the words.

Sample	Vibe	Voice
Task recap	neutral	sarah	listen
Same recap	[excited]	sarah	listen
Same recap	[weary] [sighs]	sarah	listen
Task complete	neutral	matilda	listen

Quick Start

curl -fsSL https://raw.githubusercontent.com/punt-labs/vox/368327b/install.sh | sh

Restart Claude Code, then:

/vox y        # hear when tasks complete or need input
/recap        # spoken summary of what just happened

Manual install (if you already have uv)

uv tool install punt-vox
vox install
vox doctor

Verify before running

curl -fsSL https://raw.githubusercontent.com/punt-labs/vox/368327b/install.sh -o install.sh
shasum -a 256 install.sh
cat install.sh
sh install.sh

Features

• Notification layer --- spoken summaries when tasks finish, chimes when Claude needs input
• Session vibe --- /vibe sets the mood for all speech. Auto-mode reads session signals (test results, lint, git ops) and adapts the voice. Manual mode lets you set it yourself. ElevenLabs expressive tags ([weary], [excited], [sighs]) color every utterance.
• Five providers --- ElevenLabs, OpenAI, AWS Polly, macOS say, and Linux espeak-ng. The full experience (natural voice, expressive tags, /vibe) requires ElevenLabs.
• Opt-in only --- no audio until you enable it, no surprises
• Voice or chime --- /mute switches to audio tones, no TTS API calls
• Graceful absence --- if punt-vox isn't installed, Claude Code works exactly as before
• MCP-native --- runs as a Claude Code plugin with slash commands and hooks
• Daemon mode --- optional single-process daemon (vox serve) fronted by mcp-proxy. Eliminates per-session overhead, deduplicates audio across sessions, and drops hook latency from ~500ms to ~15ms

What It Looks Like

Enable notifications

> /vox y

Vox enabled. You'll hear when tasks finish or need approval.
Pick a voice with /unmute @<name>.

Get a recap

> /recap

Speaking: "I refactored the authentication module into three files, added
comprehensive tests for the token refresh flow, and fixed a race condition
in the session middleware. All 47 tests pass."

Set the vibe

> /vibe banging my head against the wall

Vibe: banging my head against the wall → [frustrated] [sighs] [manual]

Auto-mode (default) reads session signals and adapts automatically --- after a string of test failures the voice sounds [weary], after a successful release it sounds [excited].

Switch to chime-only

> /mute

Muted — chimes only.

Chimes are mood-aware: when a vibe is active, chimes pitch-shift to match (bright for happy sessions, dark for frustrated ones). Eight distinct signals (tests pass/fail, lint pass/fail, git push, merge conflict, done, prompt) × three mood variants = 24 chime assets.

Commands

Command	Purpose
/vox y	Enable vox (chime notifications)
/vox n	Disable vox
/vox c	Continuous mode (spoken summaries on task completion)
/unmute	Enable voice mode (spoken notifications)
/unmute @matilda	Set session voice + enable voice
/unmute @	Browse voice roster
/mute	Chimes only --- no voice
/recap	Spoken summary of Claude's last response
/vibe <mood>	Set session mood --- voice adapts to match
/vibe auto	Auto-detect mood from session signals (default)
/vibe off	Disable vibe --- neutral voice

Providers

The full experience --- natural voice with expressive tags that respond to /vibe --- requires ElevenLabs. The other providers are fallbacks for environments where ElevenLabs isn't available.

Provider	API Key	Default Voice	Best For
ElevenLabs	ELEVENLABS_API_KEY	matilda	Recommended. Natural voice, expressive tags via /vibe
OpenAI	OPENAI_API_KEY	nova	Fast notifications, low latency
AWS Polly	AWS credentials	joanna	Natural voice, cost-effective
macOS say	—	samantha	Zero-config on macOS, offline
espeak-ng	—	en	Zero-config on Linux, offline

Auto-detection order: ElevenLabs > OpenAI > Polly (if AWS credentials valid) > say (macOS) / espeak (Linux).

CLI

punt-vox is also a standalone TTS tool, independent of Claude Code.

vox unmute "Hello world"                       # Synthesize + play
vox record "Hello world" -o hello.mp3          # Synthesize + save
vox record --from segments.json                # From JSON segments file
vox vibe excited                               # Set session mood
vox notify y                                   # Enable notifications
vox notify c                                   # Continuous spoken mode
vox speak n                                    # Chimes only
vox voice matilda                              # Set session voice
vox status                                     # Current state
vox version                                    # Print version
vox doctor                                     # Check setup
vox install                                    # Install Claude Code plugin
vox mcp                                        # Start MCP server (stdio)
vox serve                                      # Start daemon (HTTP + WebSocket)
vox daemon install                             # Register as system service
vox daemon status                              # Check if daemon is running

Roadmap

Shipped

• Mic API: unified unmute/record/vibe/who MCP tools with segment-based input
• Notification layer: /vox y|n|c, /mute, /unmute, /recap, Stop + Notification hooks
• Multi-provider TTS engine: ElevenLabs, AWS Polly, OpenAI, macOS say, Linux espeak-ng
• Claude Code plugin: marketplace install, MCP server, slash commands
• CLI: unmute, record, vibe, on/off, mute, version, status, doctor
• Ephemeral output mode (.vox/ in cwd)
• Two-channel display: ♪ panel summaries with voice/provider context
• Audio playback serialization via flock --- concurrent utterances queue instead of overlapping
• ElevenLabs streaming API for lower time-to-first-audio
• /vibe with auto, manual, and off modes --- ElevenLabs expressive tags color every utterance
• Auto-vibe signal accumulator: test pass/fail, lint, git ops feed mood detection
• Per-signal chime assets and vibe-driven chimes with mood-aware pitch shifting
• Daemon mode: single vox serve process with mcp-proxy, audio deduplication, launchd/systemd service management

Coming Soon

Feature	What It Does
Per-session voices	Each Claude Code session gets its own voice from a pool --- no more five matildas talking at once. /voice to audition and pick.
