App Description
Predictive AI Live Translation
"Kotoba" is a real-time voice simultaneous translation app developed by Kotoba Technologies, aiming to deliver the "world's best simultaneous translation experience."
The app is powered by Kotoba's proprietary speech GenAI model called "Koto".
"Koto" can predict text translations before you finish speaking (up to 0.5 seconds ahead) or generate coherent speech translations with ultra-low latency.
