GitHub Next vs Refraction

GitHub Next Copilot Voice was a voice-first coding experiment that let developers talk to GitHub Copilot inside Visual Studio Code. You spoke natural language to generate or edit code, jump to methods, run programs, toggle IDE commands, and ask for line-by-line explanations. The project page describes it as a completed research prototype formerly called Hey, GitHub.

Typing-first copilot extensions assume a keyboard for every navigation step. Copilot Voice used Microsoft embedded speech with a Copilot wake word so you could control the editor hands-free, which targeted accessibility and speed for developers who struggle with typing-heavy workflows. The trade-off was experimental scope: it required Java, competed with standard Copilot completions, and stayed in a signup-only technical preview.

GitHub concluded the Copilot Voice preview on April 3, 2024 and moved learnings into the generally available VS Code Speech extension. The GitHub Next project page now points developers there for ongoing voice interaction in VS Code rather than this standalone preview.
