Explore the tools
Prosody Trainer is a growing suite of research-based tools for exploring how written language carries stress, rhythm, phrasing, and intonation.
Rhythm Reader
A simple interface for visualizing stress and rhythm in English text.
Rhythm Reader Pro
Advanced analysis, phrase structure, meter detection, editing, and export.
Prosody Pup
A gentle guide for learning stress, rhythm, and fluent reading — one step at a time.
WALL-E Intonation Game
An interactive game for discovering how intonation changes meaning during reading.
The science
When people read silently, they often construct an internal prosodic representation — sometimes called the inner voice of reading, or implicit prosody.
Why prosody matters
Prosody helps readers organize words into meaningful phrases, distinguish emphasis, anticipate structure, and support comprehension.
What we make visible
Prosody Trainer reveals patterns of lexical stress, rhythm, phrasing, meter, and intonation that normally remain hidden during silent reading.
For teachers, clinicians, and researchers
The project is designed to support classroom demonstrations, reading intervention, psycholinguistic research, and public understanding of the cognitive science of reading.
Accessible explanations
Plain-language introductions to stress, rhythm, phrasing, intonation, and implicit prosody.
Publications
Peer-reviewed studies, conference presentations, and open materials supporting the Prosody Trainer project.
Classroom resources
Demonstrations, sample activities, and guided lessons for helping learners notice the prosody of written language.
