BACKGROUND/AIMS This study examined the spectral characteristics of American English vowels in dysarthria associated with cerebral palsy (CP), and investigated the relationship between a speaker's overall speech intelligibility and vowel contrast. METHODS The data were collected from 12 American English native speakers (9 speakers with a diagnosis of CP and 3 controls). Primary measures were ...

This study investigates how the native speakers of Japanese tell the differences of the words containing the devocalized vowels. The close vowels [K? and =/? devocalize in Japanese when they are situated between voiceless consonants and between pause and voiceless consonant. In this paper, we verify the hypothesis that the devocalized vowels are the voiceless fricatives. =M KÀVVQ? =M /ÀVVQ? =M ...

Recent research has suggested consonants and vowels serve different roles during language processing. While statistical computations are preferentially made over consonants but not over vowels, simple structural generalizations are easily made over vowels but not over consonants. Nevertheless, the origins of this asymmetry are unknown. Here we tested if a lifelong experience with language is ne...

PURPOSE In perception studies, it is common to use vowel stimuli from standardized recordings or synthetic stimuli created using values from well-known published research. Although the use of standardized stimuli is convenient, unconsidered dialect and regional accent differences may introduce confounding effects. The goal of this study was to examine the effect of regional accent variation on ...

the coalition between terms and their meaning can be as the result of phonological repetition in its speech structure and specific semantic load. this can lead to meaning distinction in choosing words and also meaning association. therefore, literally and syntactically, the phonological level cannot be separated from semantic level. earlier, the phonological association in text has been discuss...

background and aim: speech understanding almost never occurs in silence. verbal communication often occurs in environments where multiple speakers are talking. in such environments, babbling noise masks speech comprehension. consonants, in comparison to vowels, are more sensitive to noise masking. consonants provide most acoustic information needed for comprehending the meaning of the word. sin...
