TeamViewer software can facilitate remote data collection for studies initially designed for in-lab testing

Abstract

During speech perception experiments, well-controlled and calibrated stimuli are presented to the listener, whose task is often to repeat the speech stimulus heard. Researchers typically score the listener's responses in real-time, and may also record the verbal responses for scoring verification. Due to the COVID-19 pandemic, data collection on an ongoing speech perception study was halted. Our goal was to resume data collection with exactly the same stimuli and procedures while maintaining the safety of the participants and examiner. To that end, TeamViewer (v.15.7.7) software was used to administer the experiment using remote access to a research laptop. All study materials, including a laptop with the programmed experiment (MATLAB 2011) and high quality headphones were delivered to the participant's home. Stimuli developed for the experiment were recorded remotely by talkers using a microphone and recorder. A custom MATLAB script was run from the experimental laptop to facilitate collection of speech perception data. Both portions of the experiment required the use of the TeamViewer software, to instruct the participant in the experimental protocol and permit oversight of data collection. Specific methods used to conduct stimulus recordings and collect data will be discussed.
