Problem
Teachers of reading in primary schools must assess students' reading fluency manually, a process that is time‑consuming, subjective, and often limited to brief observations, making it difficult to obtain reliable, actionable data for each learner.
Solution
Leo Mejor is an Android application that automates reading fluency assessment using voice‑recognition technology. Students read aloud texts while the app records and analyzes speech to calculate words per minute, accuracy, omissions, and prosodic features such as intonation and rhythm. The platform provides a library of Lexile‑graded texts for grades 1‑8 and allows teachers to upload custom passages, ensuring alignment with curriculum goals. After each session, the app generates detailed individual and class reports, includes audio playback of the reading, and enables data export to Excel for further analysis, giving educators objective metrics to inform targeted instruction.
Target Audience
Primary customers are language teachers in primary schools (grades 1‑8) across Chile and Latin America who need efficient, objective tools to evaluate and improve student reading fluency.
