Vowel spectra, vowel spaces, and vowel identification.
Twelve Dutch vowels, each pronounced by 50 male speakers, were analyzed in 18 filter bands comparable in bandwidth with the cat's critical band. By considering the sound levels (in decibels) in these filter bands as dimensions, with a principal-component analysis the 18 dimensions per sound were reduced to four factors which together explain 75% of the total variance. The configuration of the a...
متن کاملVowel production in aphasia
This study explored a voice characteristics in aphasic patients suffering from the damage of the left and right cerebral hemispheres regardless of the aphasia type. A series of acoustic analyses were conducted including fundamental frequency in Hz (Fo), duration of the vowel "a" phonation, jitter and shimmer. A pattern of 20 male aphasic patients was included in the research. At the aphasics wi...
متن کاملIndividual differences in vowel production.
It is often assumed that a relatively small set of articulatory features are universally used in language sound systems. This paper presents a study which tests this assumption. The data are x-ray microbeam pellet trajectories during the production of the vowels of American English by five speakers. Speakers were consistent with themselves from one production of a word to the next, but the arti...
متن کاملLexical Access, Lexical Representation, and Vowel Production
Previous research (Munson and Solomon 2004; Wright 2004) has shown that both phonological neighborhood density and word frequency influence the size of the acoustic F1/F2 vowel space. This study investigated whether these influences reflect the role of real-time lexical access processes on articulation. Specifically, it examined the influence of word frequency and phonological neighborhood dens...
متن کاملVowel Lab III: Vowel Classification
Classification is ubiquitous. The ability to recognize and categorize things based on their features is fundamental to human cognition; a large part of our ability to understand and deal with the world around us is a result of our ability to classify things. Similarly, we want to design systems that are capable of recognition and categorization. We want vending machines to be able to recognize ...
