| dc.description | The primary concern for patients with Alzheimer's disease (AD) has always been the issue of memory deterioration. Since language processing involves the working memory, speech production is bound to worsen in later stages of the disease, resulting in communication breakdown between patients and their caregivers. Previous studies showed that music intervention was able to improve memory recall, reducing agitation, improve speech intelligibility, vocal intensity, and communication responses using familiar music, but few studies have explored the exposure of different types of music on speech production. In relation to this, the objective of this study was to explore the effects of different types of music exposure on the speech production, and working memory in subjects with Alzheimer's disease. A multiple case study (n = 3) was used to examine the effects of music intervention on a) speech rate, fundamental frequency (F0) range, and speech intensity (SPL) range using the Phonetogram; b) speech content using Audacity; and c) working memory using the Backwards digit span; of individuals with AD. Three elderly subjects (two in moderate, and one in severe stages of AD) completed 14 sessions (15-20 minutes/session, 2 sessions/week) on familiar and unfamiliar music, as well as audiobooks as a control, respectively, over 21 weeks in a crossover design. This study used a mixed-mode analysis method. For the quantitative analysis, separate two-way within subject repeated measures analyses were used to investigate the effects of exposure to different types of music on the speech rate, F0 range, and SPL range, respectively in the three subjects. Results showed that two out of the three subjects showed significant interaction between time and stimuli for speech rate, (subject B, F (2, 10) = 4.435, p = 0.042; and C, F (2, 18) = 3.854, p = 0.040, respectively) and F0 range, (subjects A, F (2, 18) = 3.854, p = 0.040; and subject C, F (2, 26) = 7.913, p = 0.002, respectively) when exposed to unfamiliar music. Repeated measures ANOVA was used to investigate the effects of different types of stimuli on the working memory scores; all subjects did not show any significant results, p = 0.592. Although familiar music showed limited function in increasing speech production, it may become an impetus for reminiscence and recall. Qualitative data indicated that F0 ranges, SPL ranges, and area of speech varied with the emotional states of the subjects based on exposure to different stimuli. Speech production was shown to be linked to topics of conversation. Among the three subjects, the two subjects in moderate stages,Ijazah Sarjana | |
