Production-ready French to Hindi translation API

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

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

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

Real-time French to Hindi translation

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

Does Soniox handle French dialects and accents?
