Brouwer, S., Mitterer, H., & Huettig, F. (2010). Shadowing reduced speech and alignment. Journal of the Acoustical Society of America,128(1), EL32-EL37. doi:10.1121/1.3448022.
This study examined whether listeners align to reduced speech. Participants were asked to shadow sentences from a casual speech corpus containing canonical and reduced targets. Participants' productions showed alignment: durations of canonical targets were longer than durations of reduced targets; and participants often imitated the segment types (canonical versus reduced) in both targets. The effect sizes were similar to previous work on alignment. In addition, shadowed productions were overall longer in duration than the original stimuli and this effect was larger for reduced than canonical targets. A possible explanation for this finding is that listeners reconstruct canonical forms from reduced forms.
