What is clozemaster ?
clozemaster is gamified language learning in context through mass exposure for learners of all levels. It aims to answer the question, "What should I do after duolingo?" and provide a more sentence based and contextual learning experience to complement other language learning apps like memrise and anki.
What does cloze mean and why would I want to master it?
From https://en.wikipedia.org/wiki/Cloze_test:
"A cloze test (also cloze deletion test) is an exercise, test, or assessment consisting of a portion of text with certain words removed (cloze text), where the participant is asked to replace the missing words. Cloze tests require the ability to understand context and vocabulary in order to identify the correct words or type of words that belong in the deleted passages of a text. This exercise is commonly administered for the assessment of native and second language learning and instruction."
Where are the sentences from?
All sentences and translations are from tatoeba's massive and awesome dataset, released under a CC-BY License.
How are the blanks in the sentences selected?
The cloze deletion to test, or the blank in the sentence, is the least common word in the sentence within the 10,000 (or as many as possible) most common words in the language. In other words, for a given sentence all the words in the sentence are checked against the top 10,000 words in a fequency list for that language. The least common word is then used as the cloze test. In this way the vocab learned via clozemaster is the most difficult of the most common. If a quality frequency doesn't exist for given language, one is either generated from the sentences themselves or random cloze words are selected.
Where are the frequency lists from?
The frequency lists used are from https://en.wiktionary.org/wiki/Wiktionary:Frequency_lists, except for:
  • The frequency list for Japanese was generated from JLPT vocabulary lists on http://www.tanos.co.uk/jlpt/. All of the vocabulary is sorted by JLPT level, and higher precedence is given to kanji.
The frequency lists have been modified to remove common names and pronouns.
How does the text-to-speech audio work?
The text-to-speech audio depends on your browser, device and operating system at the moment. Higher quality text-to-speech and text-to-speech for more languages gets expensive fast, though hopefully Clozemaster Pro will one day make those options possible. For now Clozemaster text-to-speech audio works best on Chrome and Safari for desktop, as well as on the mobile apps when connected to the internet.
I don't see the language I'm learning! Can you add it?
Most likely! We should be able to add most language pairings, though the number of sentences will vary, and we're working to add more all the time. Don't see the language you're learning or the language you speak? Let us know!
Do I have to sign up?
Nope, you can play as much as you'd like without signing up, but the sentences you see each round will be selected randomly and your progress won't be saved. Sign up or login to track your progress, score points and level up!
How much does clozemaster cost?
Nada. It's free to sign up and play, and always will be. We also offer Clozemaster Pro with advanced features such as more stats, favoriting sentences, and customizing game play to help keep Clozemaster running and support the continued development of awesome language learning tools. Clozemaster Pro is available for $8 per month or $60 per year with a 30-day money back guarantee. Sign up then go to https://www.clozemaster.com/pro to learn more!
How do the reviews work?
Sentences are reviewed according to space repetition intervals like those used in memrise and anki. Currently intervals are at 1 day, 7 days, 14 days, 30 days and 180 days based on how many times a sentence is answered correctly in a row. If a given sentence is new and answered correctly, it will be ready for review in a day. If the same sentence is answered correctly again, it will then be ready for review in 3 days, then 7 days. If it's then answered in correctly, it goes back an interval and will be ready for review again in 3 days. Once a sentence has been answered correctly 5 times, it is considered 100% mastered and you will no longer see it unless there are no more new sentences or sentences ready for review.
Oh no! An error!
This isn't a question, but there will be errors nonetheless. Sentences and translations are from a user curated dataset at tatoeba and frequency lists are in many cases generated from a dataset of TV and movie subtitles for a given language from https://en.wiktionary.org/wiki/Wiktionary:Frequency_lists. So there will probably be a few errors here and there. We've added the ability to report errors from within the game, and feel free to contact us anytime via the form below.
