Korean speech synthesis for production voice apps
Korean is spoken by more than 82 million people across South Korea, North Korea, United States, and beyond. If your voice agent, IVR, or narration product speaks to them, text-to-speech has to get the details right: phone numbers and codes read exactly as written, names pronounced the way Korean speakers expect, and text that mixes Korean with English spoken in one voice.
Soniox TTS generates Korean speech over a real-time WebSocket, starting audio from the first few words, or with a single REST request, through one multilingual API built for 60+ languages. Every voice speaks Korean, you can clone your own voice, mix languages in one sentence, and get character-level timestamps.
Exceptional quality in Korean
Hear the same voice deliver natural, expressive speech in Korean and across 60+ languages with consistent quality, identity, and pronunciation.
Hallucination-free Korean speech generation
The Korean text you send is exactly what gets spoken. No invented words, dropped content, or unexpected substitutions.
