The Science of Fluency
We discarded 100-year-old textbook methods. DilSev is built on modern Neurolinguistic Programming, Spaced Repetition, and hyper-realistic AI Voice Synthesis.
Cognitive Spaced Repetition
Your brain is designed to forget. Our algorithm tracks your memory decay curve and re-introduces vocabulary at the exact moment you are about to forget it, locking it into your long-term memory permanently.
Phoneme-Level Analysis
Sound native. DilSev’s AI doesn't just tell you if you are right or wrong. It analyzes the exact micro-frequencies of your voice and visually shows you how to adjust your tongue and jaw to perfect the accent.
