“…Some of these studies rely on questionnaires or interviews to gain insights about the informants' background and attempt to examine how intelligibility is affected by or related to informants' traits. Among these traits, studies have focused on proficiency level (e.g., BENT;BRADLOW, 2003;GONÇALVES, 2014;SCHADECH, 2013), familiarity with the speakers' L1 or L2 accent (CRUZ, 2008;MUNRO, 1997;GASS;VARONIS, 1984;SCHADECH, 2013), speech rate (DERWING; MUNRO, 2001), word familiarity or lexical frequency (BENT;BRADLOW, 2003;BECKER, 2013;BRADLOW;PISONI, 1999;GONÇALVES;SILVEIRA, 2015), topic familiarity (GASS; VAONIS, 1984), and listeners' L1 (BENT;BRADLOW, 2003;CRUZ, 2006a/b;SCHADECH, 2013;GONÇALVES, 2014). Some important findings in these studies, which are relevant for the present study, are summarized below.…”
