Production-ready Hindi to Spanish translation API

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

Hindi (Indo-European > Indo-Aryan > Central) and Spanish (Indo-European > Romance > Western Romance) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

Hindi is written in Devanagari and Spanish in Latin, so Soniox emits correctly scripted Spanish text.

Real-time Hindi to Spanish translation

Soniox streams the Hindi transcript and the Spanish translation on the same connection, word by word, so meaning lands while the speaker is still talking.
