Processing Reduced Word-Forms in Speech Perception Using Probabilistic Knowledge about Speech Production
Mitterer, Holger; McQueen, James M.
Journal of Experimental Psychology: Human Perception and Performance, v35 n1 p244-263 Feb 2009
Two experiments examined how Dutch listeners deal with the effects of connected-speech processes, specifically those arising from word-final /t/ reduction (e.g., whether Dutch [tas] is "tas," bag, or a reduced-/t/ version of "tast," touch). Eye movements of Dutch participants were tracked as they looked at arrays containing 4 printed words, each associated with a geometrical shape. Minimal pairs (e.g., "tas"/"tast") were either both above ("boven") or both next to ("naast") different shapes. Spoken instructions (e.g., "Klik op het woordje tas boven de ster," [Click on the word "bag" above the star]) thus became unambiguous only on their final words. Prior to disambiguation, listeners' fixations were drawn to /t/-final words more when "boven" than when "naast" followed the ambiguous sequences. This behavior reflects Dutch speech-production data: /t/ is reduced more before /b/ than before /n/. We thus argue that probabilistic knowledge about the effect of following context in speech production is used prelexically in perception to help resolve lexical ambiguities caused by continuous-speech processes.
