Production-ready Bulgarian to Hindi translation API

Real Bulgarian 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.

Bulgarian (Indo-European > Slavic > South Slavic) 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.

Bulgarian is written in Cyrillic and Hindi in Devanagari, so Soniox emits correctly scripted Hindi text.

Bulgarian and Hindi through a single stream

Bulgarian to Hindi translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Hindi translation streams mid-sentence in the same labeled token stream.

Turn it on by adding a translation block with source_language: "bg" and target_language: "hi". It runs on the same WebSocket and the same model, with no extra round trip.
