Your 900-day streak is about 75 hours, and none of them were speaking hours

A 900-day streak sounds like mastery, but it adds up to about 75 hours, roughly a seventh of what the State Department spends getting a diplomat through Spanish. Those hours built recognition: picking the right answer from options already on the screen. A stranger asking where you're from doesn't hand you options, and that gap is what this post measures.

You have a 900-day streak. A Spanish speaker asks where you are from, and you stall. You have seen "soy de" a hundred times, but the sentence does not come out, and by the time it does the conversation has moved on. Two years of daily practice made you very good at one skill, and this is not it.

Recognition and production are two different jobs

Start with what the app's own researchers measured. Jiang, Peters, Plonsky and Pajak tested 245 learners who finished the Basic content of a Duolingo English course, in the CALICO Journal, volume 41, 2024. They scored Intermediate High on average, above the Intermediate Mid the course targets. Three of the four authors work at Duolingo, so this is the friendliest evidence available, and it is good news.

Read what it tested. The study measured reading and listening. In its limitations section the authors write that the skills assessed "are both receptive," and that learners "were not assessed in productive skills such as speaking and writing, or overall proficiency." The strongest published result on app learning is a receptive one, stated as such by the people who ran it.

Duolingo does ship speaking exercises, and has since your first lesson. Its own blog lists repeat-the-word items, spoken dialogues, a microphone option on many writing exercises, and speaking-only sessions in the Practice Hub. They train your mouth, and they do not close this gap, because they put the target sentence on the screen and ask you to say it, so the retrieval step is still done for you. That step is the whole difficulty. Speaking to a person gives you a meaning and nothing else: you pull each word from memory cold and say it before the pause gets awkward.

Scheduling belongs to the receptive job too. Duolingo published a real spaced-repetition scheduler: Settles and Meeder, "A Trainable Spaced Repetition Model for Language Learning", peer-reviewed at ACL in 2016 and open-sourced. It predicts how much of an item you still remember and sets the day the word comes back. The paper decides when an item reappears, and does not claim to control which exercise it lands in, which is what sets what your mouth does.

The gap also widens with study. Laufer, in Applied Linguistics, 1998, volume 19, followed 48 Israeli school students across grades 10 and 11. In one year their passive vocabulary grew by about 1,600 word families, the words they could produce on demand by about 850, and the ratio between the two fell from 89% to 73%. The more English they learned, the larger the share they could only recognize.

The memory research has a name for this

Morris, Bransford and Franks ran the useful experiment in 1977, in the Journal of Verbal Learning and Verbal Behavior. They named it transfer-appropriate processing: memory works best when the thinking you do while studying matches the thinking the test demands. One group learned words by thinking about meaning, the other about rhyme. The meaning group won a normal recognition test, the rhyme group won a rhyme test, and the match between study and test decided the result. Two years of practice at selecting the correct answer makes you good at selecting the correct answer, and the cafe supplies no options.

Karpicke and Roediger, in Science in 2008, tell you which practice moves production. Students learned 40 Swahili-English word pairs. Those who kept retrieving the words from memory recalled about 80% a week later, against about 36% for those who kept restudying the list. The students predicted around 50% in every condition, and their predictions did not separate the groups. Pulling an item from an empty head is what makes it available later; picking from options on screen is closer to restudying.

Your streak is a seventh of a diplomat's Spanish course

Do the arithmetic. If those 900 days averaged five minutes, that is 75 hours. Put it against the only public number for how long a language takes: the US Foreign Service Institute spends 552 to 690 class hours training a diplomat in Spanish or French, Spanish over 30 weeks. Your 75 hours is a seventh of the low end, and every FSI hour is a production hour spent talking in a room, while almost none of yours were.

Four and a half hours of talking moved a measured score

One study puts a number on the dose. Saito and Akiyama, in Language Learning, volume 67, 2017, ran 30 Japanese university students learning English. Fifteen did weekly video calls with a native speaker in the United States, 30 minutes of English per call, 9 calls across one semester, so four and a half hours of talking in total. The other 15 did weekly vocabulary and grammar exercises at home, about 30 minutes a week, so both groups spent similar time.

Independent raters scored recordings before and after. The talking group improved on how easy they were to understand, with a medium effect (Cohen's d of 0.58, p = .012), and improved more on speech rate, on the number of different words per minute, and on verb and article accuracy, with large effects (d between 0.82 and 1.17). The exercise group improved on nothing at a significant level. Two limits: 15 people per group is small, and the authors say so, and their partners were trained to correct errors out loud, which an untrained conversation partner will not do unless you ask.

The transferable number there is a floor, not a ratio: about 4 to 5 hours of real conversation, spread over roughly ten weeks, moved a scored measure. One hour a week for ten weeks gets you there. Below about half an hour of conversation a week, nothing published says to expect a measured change.

FSI's published week is 23 hours in class plus 17 hours of self-study, about 1.35 hours with a person for every hour alone. FSI publishes that as a schedule and does not attribute its results to the ratio, so treat it as a shape worth copying rather than a proven cause. It is useful for one reason: it says most of your hours should be spent talking. Do not use the ratio as your target on its own. At five minutes of app time a day, one tutor hour clears 1.35 easily, and clearing it by studying less alone is not progress. The hours floor is the real test, and the ratio only tells you how to split hours once you are above it.

Measure your own gap in ten minutes

  1. Set a timer for 2 minutes. Write down every word you can produce in your target language on the topic "my morning". No app open. No dictionary. Just what comes out.
  2. Set it again for 2 minutes. Same rules, topic "my job" or "my studies".
  3. Count only the words you could say out loud to a person, with the right article or ending. Half-remembered spellings do not count.

No published benchmark says what that number should be after a year of daily app study, so use it as a baseline. Your app's word count is no comparison: it counts words met.

Now the harder version. Record 60 seconds answering one question out loud: "What did you do yesterday?" Speak without a script and keep going through every error. Play it back and count two things: seconds silent, and times you switched to English. Save it.

Expect the recording to feel worse than the test in your head. Koriat and Bjork named this illusions of competence, in the Journal of Experimental Psychology: Learning, Memory, and Cognition in 2005. When you judge how well you know something while the answer sits in front of you, you cannot subtract the help. The playback removes it.

Four numbers below are mine, not published findings, and here they are in one place. On the written test, 10 more produced words in four weeks is movement worth keeping, and fewer than 5 more means the routine is not working. On the recording, more than 20 silent seconds in 60, or more than two switches to English, means the problem is production speed rather than vocabulary. After four weeks of talking, aim to cut the silent seconds by about a third, so 20 becomes 13, and to drop to one switch or none.

What to change, and who should ignore this

If you do one thing, talk to a person once a week. It is the only change here that moves the 60-second recording, and one hour a week for ten weeks matches the dose that moved scores in the Saito and Akiyama study.

To find the person: italki lists community tutors, native speakers who do conversation practice rather than formal lessons. Reading 21 Spanish trial-lesson prices off italki's directory on 22 August 2026 gave a median of $12, with a full hour around $10 to $30. Rates move, so filter by price and read two profiles before booking. Tandem is a free exchange app where you trade an hour of your language for theirs, and a library conversation group is free.

Then run the hour to a rule. Talk for at least 40 of the 60 minutes, and time it: a pleasant hour listening to a native speaker is the failure mode. Bring four topics written down, four words each, no script. Use these: what I did at the weekend, my job, the last thing I cooked, a trip I want to take. Ask your partner to interrupt on errors, because an error nobody names is one you repeat next week, and the corrections were part of what worked in the study.

Send a tutor this sentence before the first session, in English, verbatim:

I want a speaking-practice hour, not a lesson. Please let me talk most of the time, correct my mistakes out loud when I make them, and do not send me homework or slides.

One smaller change, in the app itself. Turn off the word bank in your settings, so tap-the-tiles items become type-the-answer items, and say each answer out loud before you look.

Two honest exceptions. If your goal is reading, an app that built a large recognition vocabulary built what reading leans on hardest, and the CALICO result is the evidence. Nation, in the Canadian Modern Language Review in 2006, put the vocabulary needed to read most written text without help at 8,000 to 9,000 word families, above the 6,000 to 7,000 he gives for listening. Do not check your app's number against those: Nation counts word families, where "speak", "speaks" and "speaking" are one item, and an app counts words met once. Enjoy the novels.

If you are in your first few months, keep the routine you have. Early on you need a base of words at all, and recognizing a word is a step toward producing it. Fix this gap once you have a year behind you and still stall on "where are you from".

Name today's recording with today's date, so spanish-2026-08-24.m4a. Open your calendar, put the date ten weeks out in it, and book the first conversation hour for this week.

Move from recognizing words to producing them.

Verbamor builds cards from your own lessons and schedules them with FSRS, so review means pulling the word from memory and saying it out loud, not picking it off a list.
