Predictive Processes and Statistical Learning

Talk

The perceptual space of a speaker is shaped in infancy according to the phonological inventory of the L1. Phonological categories correlate with Categorical Perception (CP) and Perceptual Magnet (PM) effects, lowering the discrimination rate between the same category’s sounds and increasing it at the Category Boundaries (Liberman et al., 1967; Kuhl et al., 1992).

Predictive Processes and Statistical Learning

Talk

In this study we tested the hypothesis suggesting that speech production processes support prediction during speech comprehension by investigating prediction processes in a population with impaired speech-motor control, i.e., adults who stutter (AWS). We reasoned that, if production and prediction are supported by common processes, people with impaired production should also show anomalous...

9. The role of non-acoustic sublexical probabilistic phonotactic cues during speech perception

Predictive Processes and Statistical Learning

Talk

All current models of speech perception assume language processing is grounded in acoustic-phonetic properties of the speech signal (e.g., Mattys et al., 2012). However, considerable empirical evidence shows knowledge about non-acoustic probabilistic sublexical cues can influence speech perception (e.g., Auer & Luce, 2005). The present study aimed to investigate the contribution of...
