About

Charlie Nagle is an Associate Professor in the Department of Spanish & Portuguese within the College of Liberal Arts at the University of Texas at Austin. His research focuses on second and additional language acquisition, speech learning, speech perception and production, individual differences, and quantitative research methods. His expertise also encompasses phonetics and phonology, as well as acoustic phonetics. As the Director of the Speech Learning Lab, he contributes to advancing understanding in these areas, supporting both academic and practical applications related to speech and language learning.

  book1st authorCorresponding

  This book offers a comprehensive resource on the state-of-the-art in L2 pronunciation, surveying the most up-to-date theoretical and methodological developments to highlight the multidimensional nature of pronunciation scholarship and directions for future research. The volume examines both speech perception and production, including the perception-production link. The book explores production from a range of perspectives, including acoustic analysis of specific features and listener-based ratin…

• Comparing lower and higher variability multi-talker perceptual training

  Applied Psycholinguistics · 2025-01-01 · 4 citations

  articleOpen access1st authorCorresponding

  Abstract One of the main challenges individuals face when learning an additional language (L2) is learning its sound system, which includes learning to perceive L2 sounds accurately. High variability phonetic training (HVPT) is one method that has proven highly effective at helping individuals develop robust L2 perceptual categories, and recent meta-analytic work suggests that multi-talker training conditions provide a small but statistically reliable benefit compared to single-talker training.…

• With “crisis” comes opportunity: Using invariance testing to understand and improve measurement models (A response to Al-Hoorie et al., 2024)

  Studies in Second Language Acquisition · 2025-09-01 · 2 citations

  articleOpen access1st authorCorresponding

  Abstract Al-Hoorie et al. (2024) have described L2 Motivational Self System research as having a “validation crisis.” In this response, I offer a brief history of recent motivation research to contextualize how we reached this point. I then discuss measurement invariance testing, the purpose of which is to ensure that the proposed measurement model holds across groups or time. Crucially, invariance testing is a necessary precursor to subsequent analyses because if invariance is not upheld, it is…

• Sound communities: A quantitative proposal for studying bilingual speech

  2025-03-03 · 1 citations

  preprintOpen access

  Bilingualism researchers have intensively studied how learning and using multiple languagesaffects all levels of linguistic structure. In this strand, examining diversity in the bilingualexperience and the extent to which variables like language dominance regulate crosslinguisticinteraction has been of special interest. However, most studies sample small groups of bilingualsfrom a single research site, creating a twofold generalizability problem. First, with small samplesit is unlikely that rese…
