Effects of context-sensitive phonetic variation and lexical structure on the uniqueness of words

چکیده
Phonetic context can affect speechreading confusions for phonemes. h Experiment I, behavioral experiments were performed to examine effects of context-sensitive phonetic variation on the visual confusability of consonants and vowels. h Experiment H, compubtional experiments were perfomed to assess the importance of patterns of context-sensitive visual codusability on the uniqueness of words in the lan~e. Results from Experiment I further support the conclusion that phonetic context tiuences phoneme confusability. The compu~tional experiments in Experiment ~ provide evidence that the distribution of words in English substantially preserves lexical uniqueness even when phonetic variability is taken into account.

How discourse context shapes the lexicon: Explaining the distribution of Spanish f- / h- words
Using a corpus of Medieval Spanish text, we examine factors affecting the Modern Standard Spanish outcome of the initial /f/ in Latin FV-words. Regression analyses reveal that the frequency of a word's use in extralexical phonetic reducing environments and lexical stress patterns significantly predict the modern distribution of f-([f]) and h-(Ø) in the Spanish lexicon of FV-words. Quantificatio...

متن کاملThe Specificity of Online Variation in Speech Production
Phonetic variation is sensitive to lexical properties of words, such as frequency and neighborhood density, as well as contextual properties, such as predictability. Previous studies of lexically-induced variation have observed that both vowels and consonants are phonetically enhanced in words from dense neighborhoods, and have suggested that this effect is modulated only by the number and freq...
متن کاملFirst Language Activation during Second Language Lexical Processing in a Sentential Context
Lexicalization-patterns, the way words are mapped onto concepts, differ from one language to another. This study investigated the influence of first language (L1) lexicalization patterns on the processing of second language (L2) words in sentential contexts by both less proficient and more proficient Persian learners of English. The focus was on cases where two different senses of a polys...
متن کاملNasal Coarticulation in Lexical Perception: The Role of Neighborhood-conditioned Variation
Nasal coarticulation has been shown to vary systematically in words depending on the number of phonological neighbors: words with many neighbors are produced with a greater degree of vowel nasality than words with fewer phonological neighbors [9]. This study examines the effect of this systematic low-level variation on lexical perception. The degree of nasality in natural real and nonsense word...
