We examine the mechanisms that support interaction between lexical, phonological and phonetic processes during language production. Studies of the phonetics of speech errors have provided evidence that partially activated lexical and phonological representations influence phonetic processing. We examine how these interactive effects are modulated by lexical frequency. Previous research has demo...

Given a form that is previously unseen in a sufficiently large training corpus, and that is morphologically n-ways ambiguous (serves n different lexical functions) what is the best estimator for the lexical prior probabilities for the various functions of the form? We argue that the best estimator is provided by computing the relative frequencies of the various functions among the hapax legomen...

A large-scale study of 484 elementary school children (6-10 years) performing word repetition tasks in their native language (L1-Japanese) and a second language (L2-English) was conducted using functional near-infrared spectroscopy. Three factors presumably associated with cortical activation, language (L1/L2), word frequency (high/low), and hemisphere (left/right), were investigated. L1 words ...

In this paper we present an innovative approach for utterance-level emotion recognition by fusing acoustic features with lexical features extracted from automatic speech recognition (ASR) output. The acoustic features are generated by combining: (1) a novel set of features that are derived from segmental Mel Frequency Cepstral Coefficients (MFCC) scored against emotion-dependent Gaussian mixtur...

More efficient processing of high frequency (HF) words is a ubiquitous finding in healthy individuals, yet frequency effects are often small or absent in stroke aphasia. We propose that some patients fail to show the expected frequency effect because processing of HF words places strong demands on semantic control and regulation processes, counteracting the usual effect. This may occur because ...

A comparison has been made of productive vocabulary in some normal university English majors’ theses in China and American final-year undergraduates’ papers. The research demonstrates that with family as the measurement unit, Chinese students proportionally use fewer words of the 1 st , 8th to 10th 1000 frequency level words than American students, while in terms of the 2nd to 4th 1000 frequenc...

The same 500 words were presented in 6 different word identification tasks (Experiment 1: lexical decision, semantic categorization, and 3 speeded naming tasks; Experiment 2: delayed naming). Reaction time (RT) distributions were estimated for each task and analyses tested for the effects of word frequency and animacy on various parameters of the RT distribution. Low frequency words yielded mor...

How are words represented in the human brain and can these representations be qualitatively assessed with respect to their structure and properties? Recent research demonstrates that neurophysiological signatures of individual words can be measured when subjects do not focus their attention on speech input. These automatic activations, which take the form of negative deflections of event-relate...

When an amplitude-modulated noise generated from a spoken word is presented simultaneously with the word's printed version, the noise sounds more speechlike. This auditory illusion obtained by Frost, Repp, and Katz (1988) suggests that subjects detect correspondences between speech amplitude envelopes and printed stimuli. The present study investigated whether the speech envelope is assembled f...

This paper investigates relations between word semantic density and word frequency. A distributed representations based word average similarity is defined as the measure of word semantic density. We find that the average similarities of low frequency words are always bigger than that of high frequency words, when the frequency approaches to 400 around, the average similarity tends to stable. Th...
