Otter.ai is expanding its meeting transcription service to 31 languages and preparing a feature that automatically follows conversations as speakers switch languages.
The company added 27 languages in its largest language rollout. Thirteen are available now: Mandarin Chinese, Korean, German, Italian, Cantonese, Portuguese, Russian, Indonesian, Malay, Dutch, Turkish, Vietnamese and Polish. Fourteen more, including Arabic, Hindi, Hebrew, Persian and several Nordic and Central European languages, are due later.
The planned multilingual mode will detect changes during a meeting and continue transcribing without a manual setting change. A conversation could move from English to Korean and then Portuguese while staying in one transcript. Otter says the new languages run on its own speech models, trained with public datasets and reviewed by native-speaking volunteers.
The announcement does not include error rates by language, accent or code-switching pattern. Those measurements will matter because a system can support a language while performing unevenly in noisy calls or specialized discussions. The broader coverage is available alongside Otter’s newer workplace tools, including meeting-history preparation and real-time coaching, following a $320 million funding round led by General Catalyst.
