Sequence Complexity Effects on Speech Production in Healthy Speakers and Speakers with Hypokinetic or Ataxic Dysarthria
The present study investigated the effects of sequence complexity, defined in terms of phonemic similarity and phonotoactic probability, on the timing and accuracy of serial ordering for speech production in healthy speakers and speakers with either hypokinetic or ataxic dysarthria. Sequences were comprised of strings of consonant-vowel (CV) syllables with each syllable containing the same vowe...
متن کاملSpeech serial control in healthy speakers and speakers with hypokinetic or ataxic dysarthria: effects of sequence length and practice
The current study investigated the processes responsible for selection of sounds and syllables during production of speech sequences in 10 adults with hypokinetic dysarthria from Parkinson's disease, five adults with ataxic dysarthria, and 14 healthy control speakers. Speech production data from a choice reaction time task were analyzed to evaluate the effects of sequence length and practice on...
متن کاملCepstral Analysis of Connected Speech of Hypokinetic Dysarthria and Normal Speakers
The aim of the present study was to investigate the characteristics of hypokinetic dysarthric speech through difference of measured cepstral values of speech assignment between normal adults and patient's with Parkinson's disease in Korea. Subjects of the study were 17 males with Parkinson's disease and control group was 28 healthy male adults without cranial nerve damage or disorder. The cepst...
متن کاملThe effects of familiarization on intelligibility and lexical segmentation in hypokinetic and ataxic dysarthria.
This study is the third in a series that has explored the source of intelligibility decrement in dysarthria by jointly considering signal characteristics and the cognitive-perceptual processes employed by listeners. A paradigm of lexical boundary error analysis was used to examine this interface by manipulating listener constraints with a brief familiarization procedure. If familiarization allo...
متن کاملLexical boundary error analysis in hypokinetic and ataxic dysarthria.
This investigation is the second in a series to examine a potential source of reduced intelligibility in dysarthric speech, namely the mismatch between listeners' perceptual strategies and the acoustic information available in the dysarthric speech signal. Lexical boundary error (LBE) analysis was conducted on listener transcripts from phrases produced by speakers with hypokinetic dysarthria, a...
