Otter.ai adds 13 languages ​​and previews automatic language switching – Unite.AI

Otter.ai announced a 27-language expansion of its meeting transcription service on November 10, 2026, with 13 additions available immediately and 14 more marked as coming soon. The company also previewed a multilingual mode designed to transcribe participants as they switch supported languages ​​during a meeting, without manually changing settings.

Live additions are Mandarin Chinese (Simplified), German, Italian, Cantonese, Korean, Portuguese (Brazil), Russian, Indonesian, Malay, Dutch, Turkish, Vietnamese, and Polish. English, French, Spanish and Japanese join. Arabic, Hindi, Thai, Hebrew and Persian are among the upcoming languages; Otter says the full list will cover 31 languages.

Language barriers are a documented problem for internationally distributed teams. In Capterra’s 2024 Collaboration and Productivity Survey, 42% of employees who collaborated with colleagues from other countries at least once a month identified language barriers as a top challenge. The January 2024 online survey included 6,490 full- and part-time hybrid and remote workers. Separately, 62% of respondents said they had worked with colleagues who spoke a different native language.

The language selection remains manual

Otter’s supported languages ​​documentation instructs users to select the language spoken in the original audio before recording or importing a file. If a conversation was transcribed using the wrong setting, its owner can reprocess the original recording into another transcription language on desktop or web.

Otter says its upcoming multilingual option will instead track changes between supported languages ​​as a meeting takes place, eliminating the need to pause and change settings. This feature was not part of the immediately available additions.

Automatic transcription is also distinct from translation. Selecting a transcription language produces text in the spoken language; it does not convert the meeting to another language. AI Chat can translate an existing transcript, summary, or actions without changing the original transcript. It can also switch languages ​​within the same chat and tap into multiple conversations when generating multilingual content.

Language support in the meeting workflow

Linguistic coverage extends to the work surrounding transcription. Before a call, Work Mode can use past conversations and connected apps to prepare a brief. Summaries, actions, speaker identification, AI chat, and search work in supported languages. Next, Work Mode can generate follow-up emails and CRM updates in the language used during the meeting.

Live additions incur no additional costs for all Otter plans and are available on desktop, mobile, and browser, with users selecting a supported language in their settings. Otter also invites users to express interest in beta testing upcoming languages. Its documentation states that completing the survey neither guarantees participation in the beta program nor access to a particular language.

Model operation and transcription accuracy

Otter says its speech models are trained, tuned and run on its own infrastructure rather than being wrapped around a third-party AI service, and that the audio is not sent to a third party for processing. This processing effort extends to each added language as it becomes available.

The Help Center warns that transcription accuracy may vary based on accent, pronunciation, speaking speed, background noise, and audio quality. These conditions remain relevant to the expanded list, particularly for organizations implementing transcription across diverse meeting environments.

The business value of this release lies in extending your existing meeting workflow to more languages ​​without changing plan pricing. The automatic handling of mixed language conversations remains the standout element: until shipping, the language selection remains part of the setup and the quality of the transcription still depends on the speakers and recording conditions.
