Lexical Frequency and Neighbourhood Density effects on Vowel Production in Words and Nonwords
نویسنده
چکیده
Lexical frequency and phonological neighbourhood density have been found to influence vowel production. This experiment investigated the effect of lexical frequency and phonological neighbourhood density on vowel space expansion in words and nonwords. Twenty speakers produced words varying in phonological neighbourhood density and word frequency and produced nonwords that varied in neighbourhood density. Words with low frequency and dense phonological neighbourhoods were produced with more expanded vowel spaces than frequent words with sparse phonological neighbourhoods. In contrast, nonwords from sparse neighbourhoods were produced with more vowel space expansion than those from dense neighbourhoods. The pattern for individual vowels was also investigated.

Neighbourhood density effects in auditory nonword processing in aphasia
The question how prior knowledge of words affects processing of nonwords is important with respect to the study of lexical access and lexical competition. According to the Neighbourhood Activation model (Luce & Pisoni, 1998), the auditory presentation of a word or nonword yields automatic activation of all words in the mental lexicon that sound similar. Experimental results with unimpaired list...
متن کاملPhonotactics, 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...
متن کاملProduction of English Lexical Stress by Persian EFL Learners
This study examines the phonetic properties of lexical stress in English produced by Persian speakers learning English as a foreign language. The four most reliable phonetic correlates of English lexical stress, namely fundamental frequency, duration, intensity, and vowel quality were measured across Persian speakers’ production of the stressed and unstressed syllables of five English disyllabi...
متن کاملPhonotactics: a Review
Probabilistic phonotactics refers to the relative frequencies of segments and sequences of segments in spoken words. Neighborhood density refers to the number of words that are phonologically similar to a given word. Despite a positive correlation between phonotactic probability and neighborhood density, nonsense words with high probability segments and sequences are responded to more quickly t...
متن کاملLiaison and schwa deletion in French: an effect of lexical frequency and competition?
This study aims to determine whether the production of the lexical variants created by the phonological processes of liaison and schwa deletion in French are conditioned by factors linked to lexical recognition. We hypothesise that the realisation of these variants would be favoured for words which are lexically “salient” in term of frequency and in their lexical neighbourhoods. This claim was ...
