Brief Research Commentary: The US Indigenous Food Sovereignty Movement’s Impact on Understandings of COVID‐19 in Indian Country

This research commentary provides an overview of contemporary anthropological research regarding the US Indigenous food sovereignty movement and demonstrates how it informs the impacts of COVID‐19 on Indian Country. Past anthropological research on US Indigenous foodways, while useful, has lacked US Indigenous voices and in‐depth political context. Alternatively, many current Indigenous scholars prioritize integration of this crucial political landscape, thus increasing the relevancy and application of this work. For this review, I begin by coalescing a selection of these recent research developments, primarily focusing on research undertaken by Indigenous scholars currently in, and affiliated with, anthropology. I then connect the ways in which their ethnographic and community‐based findings shed insight into challenges that arose during the Covid‐19 pandemic in 2020. Finally, I critique anthropology’s lack of support for these research projects and offer suggestions regarding future US Indigenous food sovereignty research directions.

Effects of face masks on acoustic analysis and speech perception: Implications for peri-pandemic protocols.

Wearing face masks (alongside physical distancing) provides some protection against infection from COVID-19. Face masks can also change how people communicate and subsequently affect speech signal quality. This study investigated how three common face mask types (N95, surgical, and cloth) affected acoustic analysis of speech and perceived intelligibility in healthy subjects. Acoustic measures of timing, frequency, perturbation, and power spectral density were measured. Speech intelligibility and word and sentence accuracy were also examined using the Assessment of Intelligibility of Dysarthric Speech. Mask type impacted the power distribution in frequencies above 3 kHz for the N95 mask, and above 5 kHz in surgical and cloth masks. Measures of timing and spectral tilt mainly differed with N95 mask use. Cepstral and harmonics to noise ratios remained unchanged across mask type. No differences were observed across conditions for word or sentence intelligibility measures; however, accuracy of word and sentence translations were affected by all masks. Data presented in this study show that face masks change the speech signal, but some specific acoustic features remain largely unaffected (e.g., measures of voice quality) irrespective of mask type. Outcomes have bearing on how future speech studies are run when personal protective equipment is worn.
