Problem Statement

The Claude Code desktop app currently does not support Russian language for voice input, while languages like Indonesian (~200M speakers) are supported. Russian has ~255–260 million speakers worldwide — not only in Russia, but across post-Soviet states (Kazakhstan, Belarus, Ukraine, Uzbekistan, Kyrgyzstan, Armenia, Azerbaijan, Georgia, Moldova, Baltics) and diaspora communities in Israel, Germany, USA, Thailand, and elsewhere.

Current state on Windows desktop app:

/voice slash command is not recognized ("/voice isn't a recognized command here. Some commands only work in the Claude Code terminal.")
Win + H (Windows Voice Typing) does not work inside the desktop app's input field
No language selector for voice input is visible in settings
Result: Russian-speaking users on Windows have no working voice input path inside the app.

Proposed Solution

Add Russian as a supported language for voice input in the Claude Code desktop app (Windows/macOS).
Expose /voice or an equivalent voice-input button in the desktop app UI, not only in the terminal.
Add a language selector so users can pick their preferred transcription language.

Alternative Solutions

Win + H — does not work inside the desktop app input field.
Third-party tools (Vibe, Wispr Flow) — work but require separate installation and are not integrated.
Dictating in browser and copy-pasting — high friction.
