However, it has not been established how this mechanism is related to the efficiency with which a listener processes speech. Speech processing in a non-native language offers a useful opportunity to evaluate if theta-gamma PAC is modulated by the challenges imposed by the reception of speech input in a non-native language. The present study investigates how auditory theta-gamma PAC (recorded with magnetoencephalography) is modulated in both native and non-native speech reception. Participants were Spanish native (L1) speakers studying Basque (L2) at three different levels: beginner (Grade 1), intermediate (Grade 2), and advanced (Grade 3). We found that during L2 speech processing (i) theta-gamma PAC was more highly coordinated for intelligible compared to unintelligible speech; (ii) this coupling was modulated by proficiency in Basque being lower for beginners, higher for intermediate, and highest for advanced speakers (no difference observed in Spanish); (iii) gamma power did not differ between languages and groups. These findings highlight how the coordinated theta-gamma oscillatory activity is tightly related to speech comprehension: the stronger this coordination is, the more the comprehension system will proficiently parse the incoming speech input.This research is supported by the Basque Government through the BERC 2022-2025 program, the Spanish State Research Agency through BCBL Severo Ochoa excellence accreditation CEX2020- 001010-S, the Spanish Ministry of Science, Innovation and Universities (IJC2020-042886-I to M.L.; PID2021-122918OB-I00 to M.C; RTI2018-096311-B-I00 and PCI2022-135031-2 to N.M.;) and the IKUR #neural2speech projectWILEY202320232023info:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10810/61340reponame:Addi.
