Voice AI that feels as good as it sounds
Realtime TTS 1.5 is #1 on Artificial Analysis, voted best in blind tests by thousands of real users. TTS-2 builds on that with six major upgrades: natural language voice direction for tone, emotion, speed, and pitch. Text-based voice design, where you describe a voice in words and generate it. Cross-lingual synthesis across 100+ languages preserving speaker identity. IPA phonetic control for brand names and rare words. And improved alphanumeric pronunciation. Try it free at inworld.ai/tts.
