What is Sesame AI?
Sesame Voice AI is a cutting-edge voice synthesis platform that specializes in generating highly realistic and emotionally expressive synthetic voices. Developed by Sesame Labs, this tool bridges the gap between robotic-sounding voice models and human-like speech by incorporating nuanced emotion, context-awareness, and personality into generated audio. Whether it's for games, virtual assistants, films, or branded audio experiences, Sesame aims to "cross the uncanny valley" of voice, producing voices that sound indistinguishably human.

It leverages deep learning, large-scale neural networks, and novel techniques in voice conditioning to bring personality-rich, expressive voice capabilities to creators and developers—without needing a real voice actor every time.
