“…As such, it is possible that listeners anticipated ambiguous speech input in the presence of the face mask and adjusted phonetic categories accordingly. Indeed, previous research has shown that when high frequency cues are dampened in the speech signal, listeners may upweight low frequency speech cues, which may be an adaptive weighting strategy implemented with mask use to improve speech perception, similar to acoustic cue weighting strategies observed in listeners with hearing loss (e.g., Crinnion et al, 2020 ; Fleming & Winn, 2022 ; Toscano & McMurray, 2010 ).…”

Previous research demonstrates listeners dynamically adjust phonetic categories in line with lexical context. While listeners show flexibility in adapting speech categories, recalibration may be constrained when variability can be attributed externally. It has been hypothesized that when listeners attribute atypical speech input to a causal factor, phonetic recalibration is attenuated. The current study investigated this theory directly by examining the influence of face masks, an external factor that affects both visual and articulatory cues, on the magnitude of phonetic recalibration. Across four experiments, listeners completed a lexical decision exposure phase in which they heard an ambiguous sound in either /s/-biasing or /ʃ/-biasing lexical contexts, while simultaneously viewing a speaker with a mask off, mask on the chin, or mask over the mouth. Following exposure, all listeners completed an auditory phonetic categorization test along an /ʃ/–/s/ continuum. In Experiment 1 (when no face mask was present during exposure trials), Experiment 2 (when the face mask was on the chin), Experiment 3 (when the face mask was on the mouth during ambiguous items), and Experiment 4 (when the face mask was on the mouth during the entire exposure phase), listeners showed a robust and equivalent phonetic recalibration effect. Recalibration manifested as greater proportion /s/ responses for listeners in the /s/-biased exposure group, relative to listeners in the /ʃ/-biased exposure group. Results support the notion that listeners do not causally attribute face masks with speech idiosyncrasies, which may reflect a general speech learning adjustment during the COVID-19 pandemic.

“…First, each stimulus was presented five times. Repetition helps to identify speech perception patterns, which is often employed in studies to explore how acoustic cues affect word and sentence comprehension (e.g., Fleming & Winn, 2022; Holzgrefe-Lang et al, 2016; Petrone et al, 2017). However, this approach might lead to priming, learning, and habituation effects in listeners’ use of acoustic cues.…”
