| الملخص: | This pilot study attempts to address the question of whether there is a statistically significant change
in patients’ vocal characteristics as they progress from the initial recording session (labeled as high risk suicidal) to
the second and third recording session that was collected a few days after receiving treatments. Interview speech and
reading speech were collected from five male patients and eight female patients. Using the Power Spectral Density
(PSD) feature, the normalized Euclidean distance from each vector to the separating hyperplane was measured in
order to capture the progression or regression of patients after three treatment sessions. One-tailed paired sample ttest
demonstrates statistically significant difference between the first and second session which represents
improvement. In some cases, the first and third session also demonstrates statistically significant difference which
shows that patients does not experiencing relapse |
