Universal Talking Lab
What is easy in one language is a wall in another. Talkverse designs the method for each pair — the language you speak and the one you are learning — then levels it by where real conversation actually gets harder.
Languages
Numbers under each app are its adopted cliff boundaries — the word rank at which conversation coverage reaches 55, 60, 70 and 80 percent.
Close the loop on Russian cases and verbs with about 300 words — minimum vocabulary, maximum sentences.

Method
Count every word in a large conversation corpus, rank by frequency, and accumulate. Coverage climbs steeply, then flattens — the bends are where learning gets hard. Talkverse cuts its levels at those bends, and grades each sentence by its rarest word.

Four levels
A few hundred words carry most of a conversation. Then each new word buys less and less. The four levels follow that shape.
Function words, pronouns, particles, core verbs — cases for Russian, particles for Japanese.
Negation, tense, connectives and the verbs you need every day.
The bulk of everyday vocabulary — emotions, relationships, routines.
Common nouns and adjectives. Sentences with rarer words are left out.
Design
For a Korean speaker, Japanese particles map one-to-one — but Russian cases and Thai tones are walls. Each app starts from the learner's language and attacks the target language's own difficulties.

Hangul pronunciation guides, kana and kanji mapped to Sino-Korean readings, right-to-left layouts for Arabic and Persian.
Five tones for Thai, stress for Russian, Hangul pronunciation for Hindi and Turkish, and short daily listening built from clips you choose.
Case systems, affixes and verb conjugation introduced only when the frequency data says you will meet them.
