Vowel acoustics in dysarthria: mapping to perception.
PURPOSE The aim of the present report was to explore whether vowel metrics, demonstrated to distinguish dysarthric and healthy speech in a companion article (Lansford & Liss, 2014), are able to predict human perceptual performance. METHOD Vowel metrics derived from vowels embedded in phrases produced by 45 speakers with dysarthria were compared with orthographic transcriptions of these phrase...
متن کاملVowel acoustics in dysarthria: speech disorder diagnosis and classification.
PURPOSE The purpose of this study was to determine the extent to which vowel metrics are capable of distinguishing healthy from dysarthric speech and among different forms of dysarthria. METHOD A variety of vowel metrics were derived from spectral and temporal measurements of vowel tokens embedded in phrases produced by 45 speakers with dysarthria and 12 speakers with no history of neurologic...
متن کاملPerception and Acoustics of Vowel Nasality in Brazilian Portuguese
This study explores the relationship between identification, degree of nasality and vowel quality in oral, nasal and nasalized vowels in Brazilian Portuguese. Despite common belief that the language possesses contrastive nasal vowels, literature examination shows that nasal vowels may be followed by a nasal resonance, while nasalized vowels must be followed by a nasal consonant. It is argued th...
متن کاملVowel contrast and speech intelligibility in dysarthria.
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 ...
متن کاملSensorimotor adaptation to feedback perturbations of vowel acoustics and its relation to perception.
The role of auditory feedback in speech motor control was explored in three related experiments. Experiment 1 investigated auditory sensorimotor adaptation: the process by which speakers alter their speech production to compensate for perturbations of auditory feedback. When the first formant frequency (F1) was shifted in the feedback heard by subjects as they produced vowels in consonant-vowel...
