Description
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.

Could you build this?
No Developing state-of-the-art low-latency text-to-speech models with prompt-based voice direction and zero-shot voice cloning requires proprietary model training, massive audio datasets, and specialized ML researchers.
What it would actually take: This requires designing and training neural audio codecs, diffusion models, or autoregressive audio transformers on tens of thousands of hours of studio-quality speech datasets. It requires specialized deep learning engineers, heavy GPU compute clusters for training, and custom CUDA kernels to achieve ultra-low streaming latency (<100ms). Building the model itself cannot be substituted by prompt engineering.
