A walkthrough of real VoiceCraft features — live pronunciation scoring, CEFR advancement tracking, and turn-by-turn coaching feedback.
Pronunciation, grammar, and coherence scored after every spoken turn in real time.
Adaptive CEFR tracking from A1 to C2. The coach adjusts topic complexity to your actual progress.
Immediate, structured corrections after every turn — pronunciation tips, grammar notes, and vocabulary suggestions.
Business, travel, culture, debate, and daily life scenarios — each one designed to challenge your current CEFR level.
Track vocabulary range, precision, and register across sessions — the coach flags over-used words and suggests richer alternatives.

Coherence
How well your ideas connect — topic relevance, logical flow, and discourse markers.
Vocabulary
Word range, precision, and register across topics — with synonym suggestions after each session.

Adaptive A1–C2 classification that updates as you improve, adjusting topic difficulty accordingly.
