Give your agent a voice. Use when the user wants the agent to speak, read aloud, or have voice responses.
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
Give your agent a voice. Audio responses powered by Kokoro TTS β a compact, naturally expressive model running entirely on-device.
Highly optimized response time thanks to on-the-fly audio streaming technology. 100% free, no API keys required. Inspired by Samantha and Sky. β‘ On-the-fly Streaming β Audio plays as it generates, very low latency π The Voice of an angel β Cutting-edge local text-to-speech model Kokoro TTS π§ TTS Daemon β Keep the model warm in RAM for instant responses (can be disabled to save RAM) π₯οΈ Persist Mode β Drag & drop audio, paste text, use as a voice station π§ Fully Configurable β Voice, speed, visualizer, notification sounds π MLX + PyTorch β Native Metal acceleration on Apple Silicon, PyTorch fallback everywhere else π¨ Real-time Visualizer β Floating 60fps LED bars that react to speech (macOS only)
python3 SKILL_DIR/scripts/setup.py Note: SKILL_DIR is the root directory of this skill β the agent resolves it automatically when running commands. The setup wizard will: Detect platform and select TTS engine (MLX on Apple Silicon, PyTorch elsewhere) Find or install the appropriate TTS backend (mlx-audio or kokoro) Install espeak-ng (Homebrew on macOS, apt on Linux) Patch espeak loader if needed (macOS compatibility) Compile the native visualizer binary (macOS only) Download the Kokoro model Create config at ~/.her-voice/config.json Check status anytime: python3 SKILL_DIR/scripts/setup.py status
After setup, configure the agent and user names: python3 SKILL_DIR/scripts/config.py set agent_name "Jackie" python3 SKILL_DIR/scripts/config.py set user_name "MatΓΊΕ‘" python3 SKILL_DIR/scripts/config.py set user_name_tts "Mah-toosh" TTS pronunciation tip: If the user's name is non-English, figure out a phonetic English spelling that Kokoro will pronounce correctly. Store it in user_name_tts and use that spelling whenever speaking the name aloud. The real name stays in user_name for display purposes.

When the user wants voice responses: Check voice mode β is voice enabled or did the user ask for it? Play notification sound (instant feedback while TTS generates): afplay /System/Library/Sounds/Blow.aiff & Speak the response: python3 SKILL_DIR/scripts/speak.py "Response text here" Always provide text alongside voice β accessibility matters.
The notification sound plays instantly (~0.1s) while TTS generates (~0.3-3s). This gives the user immediate feedback that the agent is responding. Configure in ~/.her-voice/config.json: { "notification_sound": { "enabled": true, "sound": "Blow" } } Available macOS sounds: Blow, Bottle, Frog, Funk, Glass, Hero, Morse, Ping, Pop, Purr, Sosumi, Submarine, Tink. Located in /System/Library/Sounds/.
The daemon keeps the Kokoro model warm in RAM, eliminating ~1.1s of startup overhead per call. The daemon auto-resolves the mlx-audio venv β no need to find the venv Python manually. # Start (persists in background) nohup python3 SKILL_DIR/scripts/daemon.py start > /tmp/her-voice-daemon.log 2>&1 & disown # Status python3 SKILL_DIR/scripts/daemon.py status # Stop python3 SKILL_DIR/scripts/daemon.py stop # Restart python3 SKILL_DIR/scripts/daemon.py restart speak.py auto-detects the daemon: uses it if available, falls back to direct model loading. The daemon is optional. Without it, speech still works β just ~1s slower per call as the model loads each time. Skip the daemon to save ~2.3GB RAM. Note: The daemon writes its PID file and socket after the model is fully loaded and ready to accept connections. They live in ~/.her-voice/ with restricted permissions (owner-only access). The daemon won't survive a reboot β start it again after restart if needed.
A floating overlay with three animated LED bars that react to speech in real-time. 60fps, native macOS (Cocoa + AVFoundation). macOS only β on other platforms, audio plays without the visualizer.

Keep the visualizer on screen between playbacks. Use as a standalone voice station: # Launch in persist mode (stays open, idle breathing animation) ~/.her-voice/bin/her-voice-viz --persist # Stream mode + persist (stays open after speech ends) python3 SKILL_DIR/scripts/speak.py --persist "Hello!" In persist mode: Drag & drop audio files (.wav, .mp3, .aiff, .m4a) onto the visualizer to play them βV pastes clipboard text β streams directly from TTS daemon with full visualizer animation Idle breathing β subtle center bar pulse when waiting for input

Mix multiple voices for a unique sound. Configure voice_blend in config: { "voice_blend": {"af_heart": 0.6, "af_sky": 0.4} } The blended voice is stored as a .safetensors file in the model's voices directory (e.g., af_heart_60_af_sky_40.safetensors). Create it by running TTS once β speak.py looks for the pre-blended file automatically.

Kokoro 82M β A compact neural TTS model with two backends: MLX (Apple's framework for native Metal GPU acceleration on Apple Silicon) and PyTorch (works everywhere). The engine is auto-detected based on platform, or can be forced via the tts_engine config option (auto, mlx, or pytorch) Streaming β Audio generates and plays simultaneously. First sound in ~0.3s (with daemon) vs ~3s batch Visualizer β Native macOS app (Swift/Cocoa) reads raw PCM from stdin, plays via AVAudioEngine with real-time amplitude metering Daemon β Unix socket server holding the model in RAM. Eliminates Python import + model load overhead on every call
