A new standard for Korean AI speech
Korean is spoken by over 82 million people worldwide across South Korea, North Korea, United States, and beyond. Production text-to-speech for Korean still breaks on the details that matter most: phone numbers get scrambled, names are mispronounced, and mixed-language text falls apart.
Soniox TTS handles the real-world patterns that other systems get wrong, delivering high-fidelity Korean speech with robust pronunciation, precise rendering of alphanumerics, natural language switching, and low-latency streaming.
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.
