Personal Language Audio Loop
Upload vocabulary sheets, news articles, books, or chat logs. EchoFactory cleans, parses, translates, and synthesizes them into neural bilingual audio loops for reflex-based learning.
Custom Loop Synthesis Dashboard
Review estimated credit costs, edit sentences, and manage pronunciation durations. Once authorized, our pipeline handles cleaner-translation alignment, voice synthesis, and package publishing on R2 storage automatically.
