Effects of Wearing Face Masks While Using Different Speaking Styles in Noise on Speech Intelligibility During the COVID-19 Pandemic

“…Clear speech benefits on speech intelligibility have been well-documented and evaluated by a variety of procedures prior to the COVID-19 pandemic (Bradlow and Bent, 2002 ; Bradlow et al, 2003 ; Ferguson, 2012 ; Smiljanic and Sladen, 2013 ; Ferguson and Quené, 2014 ; and Van Engen et al, 2014 ; Smiljanic and Gilbert, 2017b ; Rodman et al, 2020 ). Findings presented in previous literature motivated further evaluation of clear speech benefits but within simulated environments such as the ones we are currently facing in this problematic communication climate.…”

“…It has been well-established that clear speech enhances speech intelligibility by increasing acoustic-articulatory outcomes (Smiljanić and Bradlow, 2009 ; Cooke et al, 2014 ; Smiljanic and Gilbert, 2017a , b ). Clear speech has been shown to improve speech intelligibility in the various populations: second language learners (Bradlow and Bent, 2002 ), learning-impaired children (Bradlow et al, 2003 ), individuals with hearing loss (Ferguson, 2012 ; Ferguson and Quené, 2014 ), children with cochlear implants (CIs) (Smiljanic and Sladen, 2013 ), and adult with CIs (Rodman et al, 2020 ) even though the intelligibility enhancement of clear speech varies depending on the listeners groups (Ferguson and Quené, 2014 ; Smiljanic and Gilbert, 2017a , b ) and contexts (Van Engen et al, 2014 ). With accumulated evidence of clear speech enhancement for speech intelligibility, we expect clear speech benefits to improve overall communication in the COVID-19 pandemic.…”

The Perception of Regional Dialects and Foreign Accents by Cochlear Implant Users

“…Differences in the perception and encoding of fine acoustic-phonetic details of speech may influence listeners' ability to take advantage of episodic context information to make talker judgments as well as facilitate speech recognition (Nygaard & Pisoni, 1998;Nygaard et al, 1994). Poorer discrimination of talker details has previously been associated with less accurate recognition of highly variable speech in NH listeners Tamati et al, 2013) and CI users (Cleary et al, 2005;Rodman et al, 2020). CI users have also been found to have more difficulty recognizing highly variable speech produced by multiple talkers from different dialect regions (e.g., Sommers et al, 1997;Tamati et al, 2020) and foreignaccented talkers (Ji et al, 2014;Kapolowicz et al, 2020), compared to idealized lab speech, which typically involves carefully articulated speech produced by a single talker with no discernable accent.…”
