Effects Of Background Noise On The Speech Acoustics Of People With Aphasia, Kirsten Dixon
Effects Of Background Noise On The Speech Acoustics Of People With Aphasia, Kirsten Dixon
Theses and Dissertations
This study investigated the effect of hearing six background noise conditions (silent baseline, pink noise, monologue, lively conversation, one-sided phone call, and cocktail noise) on acoustic measures of speech production during story retells in people with aphasia. Eleven individuals with aphasia and 11 age- and gender-matched control participants took part in the study. Participants heard the background noise conditions through open-back headphones while they retold six short stories. The examiner calculated mean and standard deviation of intensity, mean and standard deviation of fundamental frequency (F0), and speech rate in words per minute. A Matlab application that identified pauses (i.e., periods …
The Impact Of Background Noise On The Spoken Language Of People With Mild To Moderate Aphasia: A Preliminary Investigation, Brenna Delyn Scadden
The Impact Of Background Noise On The Spoken Language Of People With Mild To Moderate Aphasia: A Preliminary Investigation, Brenna Delyn Scadden
Theses and Dissertations
This study examined how different background noise conditions affected the spoken language production of people with aphasia (PWA) when performing a story retell task. Participants included 11 adults with mild to moderate aphasia and 11 age- and gender-matched controls. Participants retold stories in a silent baseline and five background noise conditions (conversation, monologue, phone call, cocktail, pink noise). Dependent measures of speech fluency and language production measures (correct information units, lexical errors, lexical diversity, and cohesive utterances) were compared between groups and across conditions. Results reveal that background noise results in significantly lower communication efficiency (i.e., correct information units) for …
The Perceived Effect Of Pause Length And Location On Speaker Likability And Communicative Effectiveness, Julia M. Price
The Perceived Effect Of Pause Length And Location On Speaker Likability And Communicative Effectiveness, Julia M. Price
Theses and Dissertations
Previous studies have examined the effect of atypical speech pause on conversational fluency and how the conversational listener perceives the speaker. The present study investigated the effect of pause duration of increasing length and in differing sentential locations on listener perceptions of communicative effectiveness and speaker likability. One neurotypical male and one neurotypical female speaker recorded three sentences from the Quick Aphasia Battery, and artificial pauses of varying lengths (250 ms, 400 ms, 550 ms, 700 ms, 850 ms, and 1 sec) were inserted before the subject, verb, and object of each sentence. The six baseline (unmodified) sentences were also …
Physiological Arousal, Emotion, And Word Retrieval In Aphasia: Effects And Relationships, Angela Lynne Johnson
Physiological Arousal, Emotion, And Word Retrieval In Aphasia: Effects And Relationships, Angela Lynne Johnson
Theses and Dissertations
People with aphasia are known to have poor word retrieval abilities in communicative tasks. It has also been reported that they have lower, non-optimal levels of physiological arousal, which may cause lower attention levels therefore contributing to poor performance on linguistic tasks. The purpose of this study was to investigate the relationship between physiological arousal and word retrieval in adults with aphasia and neurotypical adults when presented with emotional stimuli within a confrontational naming task. Participants included 6 people with aphasia and 15 neurotypical controls. All participants completed a confrontational naming task within 3 emotional conditions (neutral, positive, negative) and …
Quantifying Speech Pause Durations In Speakers With Nonfluent And Fluent Aphasia, Brooke K. Thomas
Quantifying Speech Pause Durations In Speakers With Nonfluent And Fluent Aphasia, Brooke K. Thomas
Theses and Dissertations
This study investigates pause duration between and within utterances in the speech of 20 people with different degrees and types of aphasia: 15 with fluent aphasia and five with nonfluent aphasia. It also examines within utterance pause durations as a function of utterance position. Using aphasia speech samples collected in a previous study by Harmon (2018), Praat acoustic analysis software was used to segment words and periods of pause and measure pause duration within and between utterances. The data were analyzed using descriptive statistics, including pause duration mean, standard deviations, and interquartile range. Speech pauses were also categorized by the …
