Relationship Between Acoustic Measures And Speech Naturalness Ratings In Parkinson’S Disease: A Within-Speaker Approach, Marie I. Klopfenstein
Relationship Between Acoustic Measures And Speech Naturalness Ratings In Parkinson’S Disease: A Within-Speaker Approach, Marie I. Klopfenstein
SIUE Faculty Research, Scholarship, and Creative Activity
This study investigated the acoustic basis of across-utterance, within-speaker variation in speech naturalness for four speakers with dysarthria secondary to Parkinson’s disease (PD). Speakers read sentences and produced spontaneous speech. Acoustic measures of fundamental frequency, phrase-final syllable lengthening, intensity and speech rate were obtained. A group of listeners judged speech naturalness using a nine-point Likert scale. Relationships between judgements of speech naturalness and acoustic measures were determined for individual speakers with PD. Relationships among acoustic measures also were quantified. Despite variability between speakers, measures of mean F0, intensity range, articulation rate, average syllable duration, duration of final syllables, vocalic nucleus …
Prosody: An Important Cue To Word Learning, Monica Dasilva
Prosody: An Important Cue To Word Learning, Monica Dasilva
Electronic Thesis and Dissertation Repository
Infants rely on cues from their environment during language acquisition. Prosodic features of words are one such cue and involve changes in stress and rhythmic patterns within speech. Studies have examined prosody’s influence on word segmentation and have found it to be a useful cue for detecting word boundaries (Johnson & Seidl, 2009). What is less understood is how prosody helps infants form associations between novel labels and their referents during word learning. The present thesis investigated the influence of prosodic cues on word learning. The looking times were recorded of 13 infants (19-25 months) exposed to object-label pairings that …
Infants' Sensitivity To Fine Durational Cues In Speech Perception, Alyssa K. Kuiack
Infants' Sensitivity To Fine Durational Cues In Speech Perception, Alyssa K. Kuiack
Undergraduate Honours Theses
Previous research has indicated that infants as young as 3 days of age show sensitivity to prosodic stress patterns and can use this information to distinguish word boundaries (Christophe et al., 1994). Older infants have also exhibited an ability to use prosodic stress patterns to segment streams of speech (Echols et al., 1997) and have shown a preference for samples of speech with the patterns of prosody displayed by their native language versus the prosodic patterns typical of other non-native languages (Werker & Tees 1984, Juscyzk et al. 1993). Adults have demonstrated the ability of language discrimination based strictly on …
