Linguistic ideologies are informed by social stereotyping to maintain the "standard" variety which is often interpreted as morally superior to "nonstandard" varieties. Consequently, these ideologies racialize "nonstandard" varieties, leading to even more negative stereotypes. One outlet of such stereotypes can be observed with accentism. Although every speaker has their own accent, accents have been used to discriminate minoritized populations. However, it is still not clear whether visual information can impact accentedness judgments towards varieties that are stereotypically associated with different prestige levels. This study examines how listeners alter their accentedness judgments when they are presented with different social cues and different English varieties with varying prestige, and whether listeners' social network could impact their accentedness judgments. Three experiments were conducted to assess linguistic attitudes towards American, British, and Indian English. The first experiment showed that Indian English is not perceived positively in the context of US. These negative associations are found to be driven from lack of positive exposure to Indian English. In other two experiments, these three varieties were paired with a White face or a South Asian face. Results showed that listeners' ability to transcribe sentences (i.e., intelligibility) decreased and their accentedness judgments increased for all varieties when speech was paired with South Asian faces. However, this increase was modulated by participants' social network diversity and the geological context that they reside in (i.e., monolingual versus multilingual).These results suggest that speech perception and accentedness judgments are mediated in a circular process. First, the nonstandard varieties are racialized by stigmatization, leading their speakers to be perceived as more accented. Then, this racialization leads to judgements of any type of speech being more accented when paired with the racialized groups. The importance and implications of social networks diversity from a raciolinguistic framework in understanding speech perception and language varieties will be discussed.
