Trusted by

Production-ready Indonesian to Hindi translation API

Real Indonesian 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.

Indonesian (Austronesian > Malayo-Polynesian > Malay) 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.

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