In modern-day psycholinguistics, there is a rising interest in looking at bilingualism from a holistic perspective. Yet, only a few are the methods employed as efficient and comprehensive of all the variables and factors that affect language acquisition and the motivation for someone to seek to acquire another language. Historically, research has also recognized the extreme value of bilingualism at a neurological level (we know that it offers protection against neurodegeneration and increased grey matter presence in some brain regions, aiding in cognitive performance overall). However, we ignore the full extent of the mechanisms that aid this complex process and the trajectory the speaker takes from initial exposure to another language to becoming competent. Vocal biomarkers are a currently emerging topic in behavioral research due to their potential uses in the early detection of psychopathology and neurodegeneration, potentially by just recording a person's voice and relying on an app to analyze and provide a report. We created a comprehensive battery to measure bilingualism, including surveys and a vocal assessment, considering specific vocal patterns (jitteriness, sustentation, and others). Participants took a modified version of a golden reference test for bilingualism research, the Bilingual Language Profile, to which we added a technology usage question and a cultural influences section. We then collected voice samples from them, completing three tasks.
