Precise text-to-speech for Thai language

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

Built for the hardest parts of Thai speech

Thai is spoken by over 70 million people worldwide across Thailand, Laos, Myanmar, Cambodia, Malaysia, and beyond. Production text-to-speech for Thai 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 Thai speech with robust pronunciation, precise rendering of alphanumerics, natural language switching, and ultra-low-latency streaming.
