This research explores how accents form in multilingual Malaysia, showing that subtle combinations of consonant and vowel features distinguish speakers. Even a single word carries identifiable acoustic cues. The findings highlight how listeners rapidly perceive identity through speech and emphasize the human complexity underlying language in an era of speech technology.

This study examines how children process the speech envelope, a key acoustic feature of language. Brain data from ages 4–18 reveal a developmental shift from left- to right-hemisphere processing. This newly identified trajectory may help detect language impairments and improve early interventions in speech and language development.
