Claude Code Voice Mode Expands to 20 Languages — Including Russian, Turkish, and More

Anthropic’s Voice Mode for Claude Code just got significantly more international — and picked up a powerful scheduling feature in the same release.

What Happened

Claude Code’s voice interface now supports 20 languages total, up from 10. The new additions: Russian, Polish, Turkish, Dutch, Ukrainian, Greek, Czech, Danish, Swedish, and Norwegian.

Alongside the STT expansion, two other changes shipped:

• Opus 4.6 default behavior changed: Max and Team subscribers now get medium effort thinking by default. The previous default was heavier. To activate high-intensity reasoning, say or type ultrathink.
• /loop command added: Run Claude Code on a schedule or in a repeat loop. Combine with cron syntax to automate recurring tasks without a human trigger.

Why This Matters

The language expansion matters more than it sounds. Non-English developers have always been technically able to use Claude Code, but voice mode was English-dominant. Adding major European languages — especially Russian, Turkish, and Dutch, each with millions of developers — removes a real friction point.

The Opus 4.6 effort tier change is subtler but consequential: medium effort is faster and cheaper. For teams running Claude at scale, the default shift reduces cost without explicitly changing behavior. ultrathink becomes the escape hatch for when you need full reasoning depth.

/loop is the sleeper feature here. Persistent scheduling inside Claude Code means you can now define autonomous maintenance agents — not just one-shot tasks. A loop that reviews test failures every 30 minutes, or reformats new files on commit, runs without any external orchestration.

What Developers Should Do Now

1. Check your language setting — if you code in a non-English environment, /voice now likely supports your native language
2. Audit your Opus 4.6 prompts — with medium effort as default, tasks that needed full reasoning may need explicit ultrathink added
3. Prototype a /loop workflow — even a simple “check for TODO comments and remind me daily” loop demonstrates the new capability

The gap between “AI coding assistant” and “always-on AI coding partner” is narrowing with every release.
