Live Korean speech translation API

Production-ready Korean speech translation API

Real conversations in Korean include accents, regional dialects, code switching, and domain-specific vocabulary. Soniox is built to handle that variation in a single model, so live translation stays usable across regions and registers.

Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.

Korean belongs to the Koreanic family. Soniox translates between Korean and any of 60+ supported targets and 3,600 language pairs in total.

Meaning lands as it's spoken, not after the caption catches up.

Korean paired with 60+ languages

Both source and target. 3,600 pairs total, not English-centric.

High quality Korean output

Same model across every language, including historically underserved ones.

Native-speaker Korean STT accuracy

Accurate translation starts with accurate recognition across accents, multilingual speech, and language switching.

Korean names, numbers, and domain terms

Preserved in both transcript and translation, including phone numbers, emails, and IDs.

Korean translation is built on top of the Soniox Speech-to-Text API. Turn it on by adding a translation block to your request. Translated tokens come back interleaved with transcripts on the same stream, with no extra round trip.

Korean speech-to-speech translation

Build full spoken Korean translation by combining Soniox STT and Soniox TTS. Soniox recognizes Korean, translates it in real time, and speaks the output in the target language with low latency.

Use it for live Korean interpreters, bilingual voice agents, travel assistants, customer support, and real-time multilingual communication.

One-way or two-way Korean translation

One-way translates all speech into a single target language. Two-way keeps a bilingual conversation flowing between Korean and another language, so each side speaks naturally and hears the other in their own.
