Otter.ai is broadening its language capabilities with a new feature that can transcribe conversations even when speakers switch between languages mid-meeting. The AI note-taking platform revealed on Tuesday that it's adding 27 new languages—its biggest language expansion so far. When fully deployed, Otter will handle 31 languages, making it easier for international teams to use the platform.

The multilingual transcription feature will automatically recognize when a speaker changes languages and keep transcribing without any manual adjustments. A single call, for instance, could shift from English to Korean to Portuguese, and Otter would track the entire conversation. This addresses a frequent pain point for global teams, where language barriers often complicate meetings and collaboration.

Thirteen of the new languages are already live: Mandarin Chinese, Korean, German, Italian, Cantonese, Portuguese, Russian, Indonesian, Malay, Dutch, Turkish, Vietnamese, and Polish. The other 14—Swedish, Danish, Finnish, Arabic, Hindi, Thai, Hebrew, Norwegian, Greek, Macedonian, Persian, Czech, Hungarian, and Romanian—will be rolled out soon.

These new languages are powered by Otter's proprietary speech models. The company said it trained the models on publicly available datasets and enlisted native-speaking volunteers to review transcripts and verify accuracy.

The language expansion comes as Otter pushes beyond transcription into broader workplace AI tools, backed by $320 million in funding from General Catalyst. The company recently launched Work Mode, which draws on meeting history and connected apps to help users prepare for upcoming calls—pulling details from past customer conversations, open action items, notes from teammates' similar calls, and recent Google Drive files. Another recent feature, Live Assist, offers real-time coaching during meetings by analyzing the discussion and suggesting relevant input based on what's been said and what's unfolding in the moment.
