"% you know" ​

"% you know" is the share of an episode's running words that you already know. If an episode has 6,000 words of dialogue and you know the words behind 5,700 of them, it says 95%.

How it's counted ​

  1. The subtitle is split into words, and each word is matched to its dictionary form (its lemma) by UDPipe. "Fueron" and "voy" both count as ir.
  2. Every use counts. A word said 40 times counts 40 times. That's what makes the number match how much of the dialogue you'd follow: knowing que matters more than knowing a word said once.
  3. Some things are left out of the count: names (UDPipe tags them as proper nouns), numbers, punctuation and symbols. Not knowing a character's name isn't a gap in your vocabulary.
  4. A word counts as known if:
    • you marked it known, or chose I know it for a suggestion;
    • it's one of the most common words for your level (100 for beginner, 1,500 for intermediate, 4,000 for advanced), unless you unmarked it;
    • you have a card for it that has matured (reviewed out to an interval of three weeks or more).

A card that's still being learned doesn't count yet: you're learning it, but you'd likely miss it at full speed.

Reading the number ​

ScoreLabelWhat it means
98% and upEasy goingYou'll follow almost everything.
95–98%Just rightYou'll follow, and the new words stand out. The best range to learn from.
85–95%A stretchYou'll follow with effort; a lot to learn. Prepare the words first.
below 85%Hard goingMost lines have a gap. Study first, watch later.

These thresholds come from research on reading (the method has the references). Listening is supported by sound, faces and situation, so the same score is usually easier to watch than to read.

Why it may be off ​

  • At first, it only knows your level's common words. Tick the words you know in an episode's Words tab for your first few episodes, and every later score improves.
  • The tagger makes mistakes, especially with slang, dialect and very short lines. A misread word may show as new when you know it; mark it known and it's fixed everywhere.
  • No score ("—") means the subtitle hasn't been analysed: it's still working, the model for the language is downloading, or there's no model for that language. See Languages.
