Intervoo is an AI-powered interview preparation platform that helps you practice English speaking and build interview confidence through a proven Test-Teach-Test (TTT) framework. Each activity starts with a baseline test, teaches you a specific skill with instant rules and examples, then measures how much you improve — so you see real progress after every session.

Every activity follows three simple steps: Test 1 (Silent Baseline) — You practice a specific skill without guidance, so the AI can measure your starting point. Teach — You learn exactly what to work on with clear rules, examples, and a simple ready signal framework. Test 2 (Measured) — You practice again, and see before/after comparison showing exactly how much you improved. This structure means you don't just get feedback — you see concrete, measurable improvement in real time.

We organize all interview skills into three families: Confidence — How you sound and feel when speaking (latency, clean starts, vocal clarity). Language — How you express yourself (grammar, vocabulary, fluency). Thinking — How you structure and organize your answers (clarity of ideas, logical flow). Each category has three activities, so nine total structured lessons. You can focus on what matters most to you.

Absolutely! Intervoo is built for all levels, Pre-A1 to C2. The AI adapts to your current level, and our TTT framework means each activity is small and focused — so you build confidence skill by skill, not overwhelmed by everything at once. Pilot data shows 89% of Pre-A1 students moved to A1 in just 6 weeks.

Nine guided speaking activities across three skill families: Confidence activities — Master clean starts, vocal clarity, latency reduction. Language activities — Build grammar, vocabulary, and fluency. Thinking activities — Learn to structure and organize interview answers. Each activity is short (5–10 minutes), follows TTT, and ends with a before/after comparison showing your improvement.

Yes, every single time. You get: Instant CEFR-based report — Your level on the international standard. Skill-specific feedback — What you did well and what to focus on next. Before/after metrics — Concrete numbers showing your improvement in Test 2 vs. Test 1. Clear next steps — What to practice next to keep improving.

Intervoo complements real-world practice. Unlike friends, our AI gives you: Objective, consistent feedback — No emotions, always fair. Detailed metrics — Exactly what to work on, not vague impressions. No judgment — Safe space to fail and try again. Instant insight — See improvement in minutes, not weeks. Use Intervoo to build confidence alone, then practice with friends once you're ready.

Most students see noticeable confidence improvement in 1–2 weeks of regular practice. Significant CEFR improvement (moving between levels) typically takes 4–8 weeks depending on starting level and practice frequency.

Trainers get detailed analytics on each student's progress, CEFR level tracking, and group performance dashboards. Placement teams can assess interview readiness at scale.

Yes! The teacher dashboard provides real-time visibility into student activities, session reports, group analytics, and individual progress tracking across all CEFR dimensions.
