AbstractWe investigated to what extent responses (N=6617) by four non-native English listener groups (The Netherlands: n=1701; Germany: n=1606; Spain: n=1647; Singapore: n=1663) assigned nativeness to standard, native British and American English accents, compared with a typical Dutch English accent. We assessed to what extent assigned nativeness impacted speaker evaluations (status, affect, dynamism), and to what extent a speaker’s voice influenced speaker evaluations by analyzing listener responses to verbal and matched guises. Results showed that perceptions of a speaker’s nativeness significantly impacted speaker evaluations on all dimensions, and therefore we conclude that speaker evaluations are also based on perceptions of the nativeness of a speaker. In addition, speaker evaluations were influenced by a speaker’s voice to such an extent that this can lead to significantly more positive/negative speaker evaluations of both native and non-native English speakers. Finally, this study confirms the relevance and superiority of the matched-guise technique in accentedness research, compared with the verbal-guise technique, since the former successfully minimizes the actual impact of voice.Introduction In general, speaker evaluation research focusing on non-native English accents shows that (strong) non-native English accents, compared to native English accents, evoke more negative speaker evaluations in native English listeners, in terms of social status and (perceived) speech comprehension, but not necessarily regarding the affect a speaker evokes or a speaker’s dynamism (e.g., Cargile & Giles 1997, Fuertes et al. 2012, Hendriks et al. 2016, Kalin et al. 1980, Levy-Ari & Keysar 2010, Lindemann 2003, Munro & Derwing 1995a,b, Phiko 1997, Nejjari et al. 2012, 2021). In addition, it has been shown that negative perceptions of non-native English speaker groups by native English speaker groups may even negatively impact perceptions of non-native speakers’ trustworthiness, chances for employment and promotion opportunities in organizations (e.g., Da Silva & Leach, 2013; Leach & Da Silva, 2013, Bond & DePaulo, 2006; Carlson & McHenry 2006; Hosoda et al. 2012). Native English in the context of this article refers to the accents produced by inner circle speakers of English, such as British and American English speakers (Kachru, 1985), and non-native English listeners refer to both expanding circle English speakers (e.g., Dutch, German, and Spanish listeners in Nejjari et al. 2020; 2021), but can also include outer circle speakers (e.g., Singaporean listeners in Nejjari et al. 2020).
