“…Although the dominant theoretical perspectives have attributed L2 speakers’ difficulties in production to a lack of accurate perceptual representations for L2 sounds and have predicted a tight relationship between the two domains (Best, 1995; Best & Tyler, 2007; Flege, 1995), research has provided no evidence for a consistent relationship between L2 speech sound perception and production (Bradlow et al., 1997; Flege, 1995; Flege & Eefting, 1987b; Hanulíková et al., 2012; Hattori & Iverson, 2010; Kartushina & Frauenfelder, 2014; Nagle, 2018; Nagle & Baese‐Berk, 2021; Okuno & Hardison, 2016; Peperkamp & Bouchon, 2011; Sheldon & Strange, 1982). The strength of the relationship has been modulated by a number of variables, ranging from L2 experience and proficiency (Bohn & Flege, 1997; Jia et al., 2006; Rallo Fabra & Romero, 2012), to the level of linguistic processing explored (e.g., prelexical, phonological, lexical; see Bohn & Flege, 1997; Hao & de Jong, 2016; Melnik‐Leroy et al., 2021; Peperkamp & Bouchon, 2011), L2 sound difficulty (e.g., similar to vs. distinct from native categories; e.g., Bohn & Flege, 1992; Evans & Alshangiti, 2018; Hao & de Jong, 2016; Levy, 2009; Levy & Law, 2010; Nagle, 2018), and L2 production accuracy measures (e.g., listener‐based judgments vs. acoustic analyses; Evans & Alshangiti, 2018; Flege et al., 1999; Hattori & Iverson, 2010; Inceoglu, 2019). Therefore, for researchers to better understand the relationship between L2 perception and production, there must be strict and systematic control of participants’ linguistic experience, the difficulty of the L2 sounds, and the tasks and measures for assessing L2 production.…”
