Maya, the voice coach, runs real-time oral dialogue with natural pauses and low-latency audio responses, backed by live grammar analysis on every conversational turn.
Practice prompts translate to and from Tamil, Telugu, Hindi or Malayalam, and speaking slip-ups automatically feed a Leitner-box spaced-repetition flashcard deck (1, 2, 4, 8, 16-day spacing).
Built local-first with isolated per-user session boundaries for privacy and safety.
