Abstract

In this study, we explore whether Zoom is a viable method for collecting data for sociophonetic research, focusing on vocalic analysis. We investigate whether recordings collected through Zoom yield different acoustic measurements than recordings collected through in-person recording equipment, for the exact same speech. We analyze vowel formant data from 18 speakers who recorded Zoom conversations at the same time as they recorded themselves with portable recording equipment. We find that, overall, Zoom recordings yield lower raw F1 values and higher F2 values than recording equipment. We also tested whether normalization affects discrepancies between recording methods and found that while discrepancies still appear after normalizing with the Watt and Fabricius modified method, Lobanov normalization largely minimizes discrepancies between recording methods. Discrepancies are also mitigated with a Zoom recording setup that involves the speaker wearing headphones and recording with an external microphone.
