Comparing acoustic analyses of speech data collected remotely

Face-to-face speech data collection has been next to impossible globally due COVID-19 restrictions. To address this problem, simultaneous recordings of three repetitions the cardinal vowels were made using a Zoom H6 Handy Recorder with external microphone (henceforth H6) and compared two alternatives accessible potential participants at home: meeting application Zoom) lossless mobile phone applications (Awesome Voice Recorder, Recorder; henceforth Phone). F0 was tracked accurately by all devices; however, for formant analysis (F1, F2, F3) Phone performed better than Zoom, i.e. more similarly H6, though extraction method (VoiceSauce, Praat) also resulted in differences. In addition, exhibited unexpected drops intensity. The results suggest that format present viable option least some phonetic studies.
