Hi, I'm Chao Zhou.

I am an assistant professor in the Department of General and Romance Linguistics at University of Lisbon (ULisboa), where I received a PhD in Linguistics in 2021. Before becoming a faculty member at ULisboa, I have taught at University of Minho (2021 - 2022) and Polytechnic of Leiria (2021). My research lies at the crossroads between Second Language Acquisition and Phonology. Some specific topics that I have explored in my recent work are:

  • Perception and production in L2 speech learning
  • Acquisition of novel phonological categories across prosodic contexts
  • Interaction between phonology and orthography in (L2) speech
  • Phonetics and phonology of rhotics
  • Effective and rapid L2 Portuguese proficiency test - LextPT

    • LextPT: A reliable and efficient test for L2 Portuguese proficiency

    Vocabulary size has been recurrently shown to be a reliable indicator of second language (L2) proficiency. Among the many existing vocabulary tests for L2 proficiency, the LexTALE test and its equivalents are growing in popularity since they provide a rapid (within 5 minutes) and reliable way to assess the L2 proficiency of several languages (English, French, Spanish, Chinese, and Italian). In collaboration with Xinyi Li (Nova University of Lisbon), we developed a vocabulary size test for L2 Portuguese proficiency: LextPT. A large-scale validation study with 452 L2 learners of Portuguese demonstrates that LextPT is not only a valid and effective instrument to measure the L2 proficiency of both European and Brazilian Portuguese, but it is also highly reliable for learners with different L1 backgrounds.
