(Don't) try this at home! The effects of recording devices and software on phonetic analysis: Supplementary material

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

This study explores the effects of embodied prosodic training on the production of non-native French front rounded vowels (i.e. /y, ø, œ/) and the overall pronunciation proficiency. Fifty-seven Catalan learners of French practiced pronunciation in one of two conditions: one group observed hand gestures embodying prosodic features of the sentences they were listening to, while the other group did not see any such gestures. The learning outcome was assessed in a pretest, posttest, and delayed posttest through a dialogue-reading task and a sentence imitation task in terms of accentedness, comprehensibility and fluency scores, and through formant analysis of participant-produced target vowels. The results showed that compared to non-embodied training, embodied prosodic training yielded continuous improvement in accentedness in both tasks and improved the F2 values of French front rounded vowels (more fronted). As for comprehensibility and fluency scores, both groups showed similar levels of significant improvement. This study highlights the interaction between prosodic and segmental features of speech by showing that training with embodied prosodic features benefitted accentedness and the production accuracy of non-native vowels.
