A crucial problem in cognitive science, especially for speech processing, is sequence encoding. Models of spoken word recognition either ignore the problem (e.g., Norris et al., 2000), posit solutions incapable of representing repeated elements (e.g., Grossberg & Kazerounian, 2011), or ”spatialize” time in possibly unrealistic ways (TRACE; McClelland & Elman, 1986). An alternative that has not ...

Isolated Word Verification (IWV) is the task of verifying the occurrence of a keyword at a specified location within a speech stream. Typical applications of IWV are to reduce the number of incorrect results output by a speech recognizer or keyword spotter. Such algorithms are also vital in reducing the false alarm rate in many commercial applications of speech recognition, such as automated te...

chology and, therefore, a chapter on the topic must be selective. This chapter will first place the relevant issues in a historical context and then review the basic visual word recognition phenomena within the context of current models. It will then be argued that any successful model of visual word recognition needs to incorporate the assumption of “interactivity,” that is, that the various c...

background: according to previous studies, most of the speech recognition disorders in older adults are the results of deficits in audibility and auditory temporal resolution. in this paper, the effect of ageing on timecompressed speech and auditory temporal resolution by word recognition in continuous and interrupted noise was studied. methods: a time-compressed speech test (tcst) was conducte...

This paper proposes a new lexicon optimization method to improve recognition rate of large scale spontaneous speech recognition. Occurrence count and length of a word has strong correlation with difficulty of recognizing the word. First, we investigate the relation and make a word correctness probability model. The proposed method optimizes the lexicon by making compound words or phrases step b...

Comprehensive models of derived polymorphemic word recognition skill in developing readers, with an emphasis on children with reading difficulty (RD), have not been developed. The purpose of the present study was to model individual differences in polymorphemic word recognition ability at the item level among 5th-grade children (N = 173) oversampled for children with RD using item-response cros...
