master speaking. level up your career.
ai-powered voice practice built for developers. learn faster, retain longer, and speak with confidence — all in your terminal workflow.
built different.
built for devs.
every feature designed around how developers actually learn
pronunciation engine
real-time phoneme analysis with instant feedback. our ai listens like a native speaker and tells you exactly what to fix.
spaced repetition
sm-2 algorithm adapted for spoken language. cards surface at exactly the right moment to maximize long-term retention.
translation drills
context-aware drills that teach you to think in the language, not translate from it. full sentence audio synthesis included.
from zero to fluent.
three simple steps.
learn new cards
import vocabulary lists, use curated decks, or let ai generate cards from content you paste. every card has audio, context, and example sentences.
practice speaking
record yourself, get instant phoneme-level feedback, and replay native audio side by side. muscle memory builds fast.
review & retain
the algorithm schedules your reviews automatically. spend 15 minutes a day and watch your recall climb toward 94%.
the numbers speak.
"switched from anki six months ago. my japanese listening comprehension went from n4 to n2 level in four months. the pronunciation feedback is insane."
"i tried duolingo, rosetta stone, everything. voicecard is the first tool that actually gets how developers think. data-driven, efficient, no gamification bs."
"the spaced repetition algorithm is tuned perfectly. i do 20 minutes every morning and i've reviewed 2,400 cards in three months with 91% retention."
