Is Zoom viable for sociophonetic research? A comparison of in-person and online recordings for vocalic analysis

Jeremy Calder et al.

Summary: This study explores the viability of using Zoom as a method for collecting sociophonetic research data, with a focus on vocalic analysis. The research investigates whether recordings obtained via Zoom produce different acoustic measurements compared to recordings obtained through in-person recording equipment, even when the speech is identical. The analysis of vowel formant data from 18 speakers who recorded Zoom conversations simultaneously with portable recording equipment indicates that Zoom recordings generally yield lower raw F1 values and higher F2 values. Additionally, the study examines the effects of normalization on discrepancies between recording methods and finds that Lobanov normalization largely minimizes discrepancies.

Remote sociophonetic data collection: Vowels and nasalization from self-recordings on personal devices

Valerie Freeman et al.

Summary: The study evaluated the suitability of using personal devices for remote phonetic data collection and found that these devices conveyed vowel arrangements and nasalization patterns relatively faithfully, although absolute measurements varied, especially in the 750-1500 Hz range.

Remote sociophonetic data collection: Vowels and nasalization over video conferencing appsa)

Valerie Freeman et al.

Summary: This study evaluated the suitability of video calls for phonetic analysis, finding that three popular video conferencing apps conveyed vowel arrangements and nasalization patterns relatively faithfully, but with varying absolute measurements, especially for female speakers and within specific frequency ranges.

Comparing acoustic analyses of speech data collected remotely

Cong Zhang et al.

Summary: This study compared the performance of three devices in collecting speech data during the COVID-19 pandemic. It found that mobile phone applications showed better accuracy in tracking F0, but were more similar to Zoom and H6 in formant analysis.

How reliable are phonetic data collected remotely? Comparison of recording devices and environments on acoustic measurements

Chunyu Ge et al.

Summary: The study aims to investigate the reliability of speech data collected remotely based on controlled speech. It was found that local recordings are reliable in duration, but cloud recordings are not, different devices have comparability in F0 and F1, while significant differences exist in higher formants, spectral moments, and voice quality measures.
