The Early Vocalization System (EVA) applies the Stevens landmark theory to infant vocalizations (babbles). The landmarks are grouped to identify syllable-like productions in these vocalizations. The visiBabble system processes vocalizations in real-time. It responds to the infant's syllable-like productions with brightly colored animations and records the landmark analysis. The system reinforces the production of syllabic utterances that are associated with later language and cognitive development. We report here on the development of the visiBabble prototype and our initial field-testing.
