Slovak speech synthesis for production voice apps
Slovak is spoken by more than 5.4 million people in Slovakia and around the world. 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 Slovak speakers expect, and text that mixes Slovak with English spoken in one voice.
Soniox TTS generates Slovak 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 Slovak, you can clone your own voice, mix languages in one sentence, and get character-level timestamps.
Exceptional quality in Slovak
Hear the same voice deliver natural, expressive speech in Slovak and across 60+ languages with consistent quality, identity, and pronunciation.
Hallucination-free Slovak speech generation
