The Influence of Social Information on Speech Intelligibility within the Spanish Heritage Community

Abstract

Previous research in speech perception has shown that perception is influenced by social factors that can result in behavioral consequences such as reduced intelligibility (i.e., a listeners’ ability to transcribe the speech they hear). However, little is known about these effects regarding Spanish speakers’ perception of heritage Spanish, Spanish spoken by individuals who have an ancestral and cultural connection to the Spanish language. Given that ideologies within the U.S. Latino community often equate Latino identity to speaking Spanish “correctly” and proficiently, there is a clear need to understand the potential influence these ideologies have on speech perception. Using a matched-guised methodology, we analyzed the influence of speaker social background information and listener social background information on speech perception. Participants completed a transcription task in which four different Spanish heritage speakers were paired with different social guises to determine if the speakers were perceived as equally intelligible under each guise condition. The results showed that social guise and listener social variables did not significantly predict intelligibility scores. We argue that the unique socio-political culture within the U.S. Latino community may lead to different effects of language ideology and social expectation on speech perception than what has been documented in previous work.
