Voxlert: Voice Notifications for Claude Code Sessions with Character Voices

What Voxlert Does

Voxlert is a notification system for Claude Code sessions that provides audio alerts when sessions finish or need input. It was created to help developers running multiple Claude Code sessions simultaneously who kept missing when one completed.

Key Features and Implementation

The tool hooks into Claude Code events and speaks notifications using distinct character voices so you can identify which session is talking without looking. Available voices include StarCraft Adjutant, SHODAN from System Shock, GLaDOS from Portal, and the HEV Suit from Half-Life.

Voxlert was built almost entirely within Claude Code sessions, including:

• The hook system for Claude Code events
• Audio pipeline
• Setup wizard
• Voice pack architecture

Technical Details

The system uses an LLM via OpenRouter to convert raw Claude Code events into short in-character lines, then speaks them through local text-to-speech. Everything runs on your local machine.

Installation is done via npm:

npm install -g voxlert
voxlert setup

For TTS functionality, you need Apple Silicon or an NVIDIA GPU. Without these, Voxlert still works as text notifications.
