Feature request: Bidirectional voice mode for Claude Code in VS Code

Summary

It would be great to have a built-in voice mode in Claude Code (VS Code panel), allowing users to dictate prompts by voice and hear Claude's responses read aloud — a fully bidirectional voice experience.

Current state

• VS Code Speech extension works with Copilot Chat but not with Claude Code's terminal panel
• The only workaround is using the OS-level dictation (e.g. Win+H on Windows) to type into the input field, which is clunky and doesn't cover the response side
• Cowork mode has accessibility.voice.autoSynthesize but this doesn't apply to Claude Code in VS Code

Proposed feature

1. Voice input: A microphone button in the Claude Code panel to start/stop dictation (speech-to-text), similar to what VS Code Speech does for Copilot Chat
2. Voice output: Option to have Claude's responses read aloud (text-to-speech), especially useful for hands-free coding sessions
3. Language support: Respect the accessibility.voice.speechLanguage setting (e.g. fr-FR)

Why this matters

• Accessibility: makes Claude Code usable for developers who can't type easily
• Productivity: hands-free coding while reviewing code on screen, whiteboarding, etc.
• Natural interaction: voice is often faster for explaining complex intent than typing

Environment

• VS Code + Claude Code extension
• Windows 11, but this would benefit all platforms
