Due-Card Speaking Practice
Before each daily review, turns due flashcards into a short voice scenario and uses what the learner says—or avoids saying—to shape the next review.
When language learners open Anki each day, they can often get through dozens of cards yet still fail to recall a word they just studied in a real conversation. The product reads that day’s due flashcards and places the words in a short spoken scenario, such as ordering food, explaining a late arrival, or describing a weekend. The learner chooses a difficulty level and how many minutes they have before speaking begins.
The dialogue uses only that day’s target words plus a small set of already mastered words, rather than suddenly introducing a string of unfamiliar expressions. When stuck, the learner can ask for a hint close to the card front, an example sentence, or slower speech. The voice interface records which words were produced naturally, which were said only after a prompt, and which were repeatedly avoided.
At the end, the learner sees not a generic score but a speaking record: which words were used correctly, where they paused, and what scenario to try next time. Results can be written back as different grades, or shown for user confirmation before Anki intervals are updated. Flashcard review and speaking practice are no longer two disconnected tasks.
The first version focuses on short, solo dialogues using cards due that day. It is not open-ended conversation practice and does not replace a complete language course. It turns the vocabulary already accumulated in a deck into material the learner must say aloud once each day.
Why now
When observed on August 13, Linforge ranked 19th in Product Hunt’s new-product feed, putting “turn Anki cards into real English conversations” in front of new-product users. S1 That exposure makes it easier for learners with existing decks who fail to retrieve words when speaking to find a tool that connects daily review with speaking practice.
Target user
Language learners who maintain Anki decks but rarely say their vocabulary aloud. The trigger is opening Anki each day to clear due cards: the target words are already defined, and the learner is ready to spend a few minutes reviewing. Rather than requiring a new course, the product extends the existing card-flipping routine into a short dialogue. It fits especially naturally into the habits of people preparing for an exam, a trip, or a speaking class.
Minimal entry point
Start with a desktop companion that connects to local Anki through AnkiConnect. Use `findCards` to query due cards, then `cardsInfo` to read their fronts, backs, and fields. S2 Users first specify which fields represent target words; the first version will not try to infer complex card types. Dialogue generation uses a target-word allowlist and limits additional vocabulary. After speech is transcribed, normalize word forms and mark words as produced naturally, produced after a prompt, or unused. The end screen asks users to confirm results rather than changing intervals directly. Once confirmed, map results only to Anki’s existing answer grades, avoiding a proprietary scheduling algorithm. Anki cautions that plugins that change intervals can conflict with FSRS. S3
Punching above its weight
Find early users among authors of publicly shared language decks and heavy Anki users. Publish a standalone AnkiConnect setup guide so people can try it with existing decks without migrating them. S2 Demos should show a single due card entering a dialogue and returning as a review result. Acquisition materials can center on specific decks, such as travel English, test vocabulary, and Japanese example sentences, rather than generic AI speaking practice.
Competitors & gaps
- Koko (Talk To Your Flashcards)Google
- Koko already turns Anki flashcards into conversations and aims to use vocabulary the learner already knows. It also introduces a small number of new words and offers story tasks, speech-rate controls, and pause controls. Its public page says it serves beginners through lower-intermediate learners and currently supports Chinese and Spanish. S4 This covers the core flashcard-to-conversation experience and validates the adjacent approach. Its public materials do not emphasize reading only the cards due that day or compressing a task to fit the learner’s available minutes. They also do not explain how it distinguishes words produced naturally, produced only after a prompt, and repeatedly avoided. The more important opening is the review loop: whether practice results return to the original cards and, after user confirmation, affect Anki scheduling. Due-Card Speaking Practice can focus on the daily card-clearing workflow rather than broader, story-based language practice.
How it makes money
Monthly subscription. The free tier connects one deck and includes a limited number of short dialogues; paid plans add more decks, practice history, and review write-back. Because voice-model costs rise with practice volume, time beyond the included allowance can be billed separately.
The case against
If speech recognition misses a target word, genuine mastery may be mistaken for avoidance. Accents, inflections, homophones, and self-corrections all make classification harder. The reverse error is more troublesome: a learner who merely repeats a prompt may be recorded as having actively retrieved the word. If those results are written directly to Anki, inaccurate records can distort subsequent scheduling, and FSRS compatibility requires care. S3 A dialogue constrained too tightly by the word list can sound stiff; loosen the constraint too much, and unfamiliar expressions enter the session. Desktop Anki and its local interface also exclude people who review only on mobile. Voice-processing cost, latency, and recording privacy will continue to affect retention and gross margin.
