Voice dictation in VS Code: how the built-in VS Code Speech extension compares to FluidVox

VS Code Speech is Microsoft's official extension that adds voice input to the editor and to chat views in Visual Studio Code. It's free, processes audio entirely on-device, and doesn't require an internet connection. It's a separate install, not something built into VS Code by default.

Not out of the box — you install the free VS Code Speech extension (ms-vscode.vscode-speech) to add it, which Microsoft shipped starting with the February 2024 (v1.87) release. Once installed, it adds dictation commands to the editor and a microphone icon to chat views. FluidVox, by contrast, works the moment it's installed, in VS Code and every other app on your Mac or PC.

Install the VS Code Speech extension from the Marketplace, then run "Voice: Start Dictation in Editor" from the Command Palette, or press the shortcut. Speak, and press Escape (or the shortcut again) to stop. FluidVox's setup is similar in spirit — install once, hold a hotkey, speak — but the hotkey works in the VS Code editor, the terminal, chat panes, and every other app, not just the editor.

VS Code Speech's editor dictation defaults to Option+Cmd+V on Mac and Ctrl+Alt+V on Windows/Linux; chat voice input uses Cmd+I / Ctrl+I. Both support press-and-hold "walkie-talkie" mode. FluidVox uses Fn hold-to-talk on Mac (Fn+Space for hands-free) and Ctrl+Shift+Space on Windows, and the same hotkey works everywhere, not just inside VS Code.

Yes, through the same VS Code Speech extension. Once you've installed GitHub Copilot Chat and signed in, adding VS Code Speech puts a microphone icon in every Copilot Chat view, so you can speak prompts instead of typing them. It's Copilot-specific — the chat voice button only appears in VS Code's native chat interfaces, not in third-party AI panels or the terminal.

VS Code Speech's microphone button is built for VS Code's own chat views (Copilot Chat and any extension using the same Chat API) — it isn't a system-wide dictation tool, so whether it appears depends on how a given AI assistant is integrated. FluidVox sidesteps the question entirely: it types into whatever text field has focus, so dictating into a Claude Code terminal session, Cursor's chat panel, or a plain shell prompt all work the same way. See our dedicated look at voice input for Claude and Claude Code.

Yes. VS Code Speech is a free extension on the Visual Studio Marketplace, and editor dictation doesn't require a GitHub Copilot subscription — only the Copilot Chat voice button does, since it lives inside the Copilot Chat view. FluidVox is a separate paid app (from $2.99/month or $39 one-time for the Local plan), with a 14-day free trial and full access before you pay anything.

VS Code itself is open source, and the VS Code Speech extension is documented on the microsoft/vscode wiki, but the extension's packaged speech-recognition models aren't something most developers need to inspect — you install it from the Marketplace like any other extension. FluidVox is closed-source commercial software that runs on-device Whisper and Parakeet models for its Local plan.

The recurring theme is that VS Code Speech is a genuinely useful accessibility win for basic dictation, but developers doing it all day tend to want more: custom vocabulary that sticks without re-training, dictation that works outside the editor and chat panes (terminal, browser, Slack), and formatting that adapts automatically to comments versus commit messages versus documentation. Those gaps are exactly what tools like FluidVox are built to close.

VS Code Speech uses general-purpose speech recognition across 26 languages, without a way to add project-specific terms (API names, library spellings, teammates' names) that stick permanently. FluidVox maintains a personal dictionary and replacement rules that auto-learn from your corrections, so terms like a library name or an internal service get typed correctly every time.

Yes. FluidVox types into any text input in VS Code, including the code editor, integrated terminal, comment fields, commit message box, and chat panels — it doesn't need VS Code-specific integration because it works the same way in every app.

FluidVox types plain text at your cursor position, so it's built for comments, strings, documentation, and commit messages rather than dictating code syntax character by character. The Code style keeps casing and technical terms intact, which matters for comments referencing variable or function names.

Yes. Hold the hotkey while the terminal panel has focus and FluidVox types your dictated text as a command or description, the same as it would in any other text field — no extension or configuration specific to the terminal is required.

The Code style is designed for exactly this: technical phrasing, preserved casing for identifiers, and concise punctuation suited to comments and docstrings. FluidVox's per-app style matching can apply Code automatically whenever VS Code is the focused app, so you don't have to switch styles by hand.
