Precise text-to-speech for Indonesian language

Generate high-fidelity, hallucination-free Indonesian speech. Built for the hardest parts of production TTS: alphanumerics, foreign names, and low-latency streaming.

Built for the hardest parts of Indonesian speech

Indonesian is spoken by over 270 million people worldwide primarily in Indonesia, with speakers around the world. Production text-to-speech for Indonesian 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 Indonesian speech with robust pronunciation, precise rendering of alphanumerics, natural language switching, and ultra-low-latency streaming.
