An FGREP Investigation into Phonotactics

نویسنده

  • Peter Kleiweg
چکیده

We discuss experiments with neural networks being trained in a phonotactic processing task. A recurrent network not only learns to predict the next letter given a partial processed word, but also learns to represent the letters in a manner meaningful to the processing task. To this end, we use Miikkulainen’s (1993) FGREP, augmented with an algorithm we call dispersion, to improve distinctness among the set of letter representations. Our goal is to create a more realistic model of how humans might process natural language.

An approximation approach to the problem of the acquisition of phonotactics in Optimality Theory

The problem of the acquisition of phonotactics in Optimality Theory is intractable. This paper offers a way to cope with this hardness result: the problem is reformulated as a well known integer program (the Assignment problem with linear side constraints) paving the way for the application to phonotactics of approximation algorithms recently developed for integer programming. Knowledge of the ...

The Error-driven Ranking Model of the Early Stage of the Acquisition of Phonotactics: an Initial Result on Restrictiveness *

Nine-month-old infants are already sensitive to the distinction between licit and illicit forms (Jusczyk et al. 1993). They thus display knowledge of the target adult phonotactics at an early stage when morphology is plausibly still lagging behind (Hayes 2004) and the acquisition of the native language lexicon has barely begun (Fenson et al. 1994). How can this early stage of the acquisition of...

Phonotactics, density, and entropy in spoken word recognition

Previous research has demonstrated that increases in phonotactic probability facilitate spoken word processing, whereas increased competition among lexical representations is often associated with slower and less accurate recognition. We examined the combined effects of probabilistic phonotactics and lexical competition by generating words and nonwords that varied orthogonally on phonotactics a...

Comparative Phonotactics

1 Two kinds of phonotactics I contrast the notions of “absolute phonotactics” and “comparative phonotactics.” Absolute phonotactics is the study of well-formedness in phonology. The topic has a long history, but was laid out with particular cogency by Chomsky and Halle (1965), who noted that speakers have phonotactic judgments even of words they have never heard before; thus blick [blɪk] is non...

Phonotactics and morphophonology in early child language: Evidence from Dutch

This research investigates children’s knowledge of how surface pronunciations of lexical items vary according to their phonological and morphological context. Dutch-learning children aged 2.5 and 3.5 years were tested on voicing neutralization and morphophonological alternations. For instance, voicing does not alternate between the pair [pɛt]∼[pɛtən] (cap∼caps) but does in [bɛt]∼[bɛdən] (bed∼be...
