Built on decades of language-acquisition research

TPR

James J. Asher, professor emeritus of psychology, San José State University (1960s–70s)

Total Physical Response (TPR) is a language-teaching method developed by James Asher in the 1960s-70s, based on the idea that we learn language the way children learn their first one: by physically responding to what we hear, long before we try to speak it. Spokn applies TPR's principles — embodiment, listening-first, low stress — in a self-study audio format.

TPRS

Blaine Ray, a California high-school Spanish teacher (1990s)

TPRS (TPR Storytelling) is a method created by Blaine Ray in the 1990s that combines Asher's TPR with Krashen's acquisition theory, delivering massive comprehensible input inside an engaging story. Its signature technique, "circling," asks a series of easy questions about one statement so target language is heard dozens of times without feeling like drilling — this is the direct model behind every Spokn lesson.

Comprehensible Input

Stephen Krashen, linguist, University of Southern California (1970s–80s)

The Input Hypothesis, developed by Stephen Krashen in the 1970s-80s, holds that we acquire language by understanding messages slightly above our current level ("i+1") — not by memorizing grammar rules. Spokn builds every lesson to be understandable through context and rephrasing, so new language lands as comprehensible input rather than a vocabulary drill.
