TL;DR: This paper showed that interstress intervals in English, a stress-timed language, are no more isochronous than interstressing intervals in Spanish, a syllable-time language, or any of the other languages investigated.

TL;DR: Both age of L2 learning and amount of continued L1 use were found to affect degree of foreign accent, and gender, length of residence in an L2-speaking country and self-estimated L1 ability, on the other hand, were not found to have a significant, independent effect on overall L2 pronunciation accuracy.

TL;DR: This paper found that the phonetic space of adults is restructured during L2 learning, and support the hypothesis that equivalence classification prevents experienced L2 learners from producing similar L2 phones, but not new L 2 phones, authentically.

TL;DR: In this paper, it is suggested that the tendency for quantal relations among these acoustic, auditory, and articulatory parameters is a principal factor shaping the inventory of acoustic and articulation attributes that are used to signal distinctions in language.

TL;DR: The authors assessed the effect of English language experience on non-native speakers' production and perception of English vowels and found that the experienced nonnative subjects produced and perceived English vowel more accurately than did the relatively inexperienced nonnative subject.
