Trusted by

Production-ready Spanish to Galician translation API

Real Spanish speech includes accents, regional dialects, code switching, and domain-specific vocabulary. Soniox recognizes it in a single model and streams Galician while the speaker is still talking.

Spanish and Galician both belong to the Indo-European > Romance > Western Romance family, so cognates and shared structure carry over cleanly into the translated Galician output.

Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.
