Hindi to Korean speech translation API

Stream Hindi (हिन्दी) speech and get Korean (한국어) back in real time. One WebSocket, ISO codes hi to ko, and ultra-low latency for voice agents and live apps.

Trusted by

Production-ready Hindi to Korean translation API

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

Hindi (Indo-European > Indo-Aryan > Central) and Korean (Koreanic) 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 Korean in Hangul, so Soniox emits correctly scripted Korean text.

Hindi and Korean through a single stream

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

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