Voca is a Claude Code plugin that adds an ambient voice interface to your coding sessions. It listens to your microphone, transcribes speech in real-time, and speaks back—all running locally on Apple Silicon. No cloud APIs, no latency, no data leaving your machine.

✨ Features

• 🗣️ Natural Voice Interface: Talk to Claude Code naturally as you work.
• ⚡️ Real-time Processing: Sub-second transcription ensures fluid conversations.
• 🔒 Privacy First: 100% local inference. Your audio never leaves your machine.
• 🎙️ Advanced Audio Routing: Seamless text-to-speech and voice activity detection built directly in.
• 🔁 Instant Focus Handoff: Starting voice mode in a second session interrupts the active poll and transfers ownership immediately.

🚀 Getting Started

Prerequisites

All inference runs on-device using MLX.

⚠️ Requirement: macOS with Apple Silicon (M1+) is required to run Voca.

Installation

Add the marketplace and install the plugin:

/plugin marketplace add patelnav/voca
/plugin install voca@patelnav-voca

Setup & Usage

1. Configure Devices: Run the setup command to configure your audio input/output devices and verify that everything is working:

   /voca:setup
   

2. Start a Voice Session: Once setup is complete, start the ambient voice interface:

   /voca:start
   

Voca uses token-based HTTP polling under the hood. The first poll claims focus; every later poll in that session reuses the returned token. Starting voice mode in another session claims a new token and hands off listening immediately.

Claude will now listen in the background and respond seamlessly to your voice.
