Abstract

This study investigates speech and voice features as classifiers for depression, schizophrenia, and healthy controls. Speech and voice features were calculated from picture descriptions of 240 speech samples (20 participants with SSD, 20 with MDD, and 20 HC each with 4 samples). Support vector machine (SVM) models achieved high accuracy (0.947 for HC vs. SSD, 0.920 for HC vs. MDD, and 0.932 for SSD vs. MDD). The most important features were articulation coordination, pauses per minute, and speech variability, showing moderate correlations with positive symptoms for SSD. These findings suggest differences in speech characteristics related to psychomotor slowing, alogia, and flat affect among the groups.
