OtterAI, an AI meeting notes service, is unveiling a multilingual transcription feature that follows conversations and transcribes them even when participants switch languages in a single meeting, TechCrunch reported on Nov. 9 local time.

OtterAI is adding 27 supported languages. It is the largest language expansion to date. Once the rollout is complete, the total number of languages Otter supports will rise to 31.

The new feature automatically detects language changes. Transcription continues without users changing settings. Even if a call shifts from English to Korean and Portuguese, OtterAI transcribes the conversation to the end. The feature targets global teams that face difficulties in meetings and collaboration due to language differences.

Thirteen of the added languages are available now. They are Mandarin Chinese, Korean, German, Italian, Cantonese, Portuguese, Russian, Indonesian, Malay, Dutch, Turkish, Vietnamese and Polish. The remaining 14, including Swedish, Arabic, Hindi and Thai, are due to be supported soon.

The new languages run on OtterAI’s in-house speech models. The company explained that it trained the models on public datasets and reviewed transcription results with native-speaker volunteers to verify accuracy.

An OtterAI spokesperson said, "Otter is breaking down language barriers," adding, "Any company, in any country, can build a record system that captures decisions that come out of voice AI communications."

OtterAI is expanding beyond transcription into AI tools for work after receiving a $320 million investment from General Catalyst. Its recently introduced Work Mode supports preparation for the next call by using apps connected to meeting history. Live Assist analyses conversations during meetings and provides advice in real time.
