Slovenian speech synthesis for production voice apps

Slovenian is spoken by more than 2.5 million people in Slovenia 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 Slovenian speakers expect, and text that mixes Slovenian with English spoken in one voice.

Soniox TTS generates Slovenian 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 Slovenian, you can clone your own voice, mix languages in one sentence, and get character-level timestamps.

Exceptional quality in Slovenian

Hear the same voice deliver natural, expressive speech in Slovenian and across 60+ languages with consistent quality, identity, and pronunciation.

Hallucination-free Slovenian speech generation

The Slovenian text you send is exactly what gets spoken. No invented words, dropped content, or unexpected substitutions.
