Production-ready Korean to Chinese translation API

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

Korean (Koreanic) and Chinese (Sino-Tibetan > Sinitic) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

Korean is written in Hangul and Chinese in CJK, so Soniox emits correctly scripted Chinese text.

Real-time Korean to Chinese translation

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

Frequently asked questions

How do I translate Korean to Chinese with the API?

Add a translation block to your real-time request with source_language "ko" and target_language "zh". Soniox transcribes Korean and streams the Chinese translation over the same WebSocket.

Is Korean to Chinese translation real-time?

Yes. Soniox streams Chinese while Korean is still being spoken, so meaning arrives mid-sentence instead of after the sentence ends.

What about translating Chinese to Korean?

That direction is supported too. See the Chinese to Korean page, or use two-way translation to run both directions in one session.

Does Soniox handle Hangul to CJK output?

Yes. Soniox outputs correctly scripted Chinese text in CJK directly in the token stream.

Does Soniox handle Korean dialects and accents?

Yes. Soniox handles Korean dialects like Seoul, Gyeongsang, and Jeolla in a single model, so Chinese translation stays accurate across regions.

Which other providers support Korean to Chinese?

Based on their public docs, OpenAI, Azure, and Speechmatics list both Korean and Chinese for real-time translation. Soniox is the only one that also supports two-way live translation across 60+ languages.

How fast is Korean to Chinese translation?

Soniox streams Chinese as Korean is being spoken, with ultra-low latency. Translation arrives before the sentence ends.
