Relative difficulty in the L2 acquisition of the Spanish dorsal fricative

Research on relative difficulty in L2 production has revealed that learners target the most salient parameter when acquiring new sounds (Colantoni & Steele, 2008). For example, L1 English-L2 French learners acquire the more salient fricative manner of the French /ʁ/ before the voicing and duration parameters (Colantoni & Steele, 2007, 2008). Previous work in this framework has not compared the acquisition of place and manner parameters. If the more salient parameter is targeted first, we should expect L2 learners to acquire the manner of articulation before the place of articulation, given that manner is a more salient feature than place (Miller & Nicely, 1955; Bedoin et al., 2013). This hypothesis was tested by investigating the L2 production of the Spanish voiceless dorsal fricative by L1 English speakers living in Madrid, a region in which the fricative has a strident realization (Hualde, 2014) and a uvular place of articulation (Ibabe et al., 2016). Fourteen L1 English-L2 Spanish speakers and 14 native Spanish controls performed a picture description task that elicited the target in two vocalic contexts: [aχe, eχa]. An acoustic analysis revealed that the L2 speakers produced fricatives with a similar amplitude compared to controls. However, in the [eχa] context, the learners produced fricatives with a more anterior place of articulation and less frication. The results are consistent with the finding from previous work that learners focus on the most salient property when learning new segments, and provide further evidence that vocalic context is an important factor in production difficulty
