Claude STT

Speech-to-text input for Claude Code. Hold a hotkey, speak, and your words appear in the input field — all processed locally.

Install

Inside a Claude Code instance, run the following commands:

Step 1: Add the marketplace

/plugin marketplace add jarrodwatts/claude-stt

Step 2: Install the plugin

/plugin install claude-stt

Step 3: Run setup

/claude-stt:setup

Done! Press Ctrl+Shift+Space to start recording, press again to stop and transcribe.

Note: Setup installs dependencies (uv if available, otherwise a local .venv), downloads the Moonshine model (~200MB), and checks microphone permissions.

What is Claude STT?

Claude STT gives you voice input directly into Claude Code. No typing required — just speak naturally.
