Investigating the course of recovery in high risk suicide using power spectral density

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 af...
