Nova-3 Multilingual Expands to 55 Languages and Adds Language Hinting

Deepgram expanded Nova-3 multilingual transcription to 55 languages and added language hints. It can transcribe audio that switches languages during a conversation, in batch or live streams.

Existing model=nova-3&language=multi requests use the new model automatically. Add a language_hint for each language you expect, such as English and Spanish, to bias detection. Responses include languages_hinted with the normalized hints you supplied.

To keep the older 10-language model, pin version=2026-01-27.9107 for batch or version=2026-01-27.9249 for streaming. The 55-language model and hints aren't available for self-hosted deployments yet.
