    Area of Science:

    • Psychology
    • Speech Analysis
    • Psychotherapy Research

    Background:

    • Understanding the relationship between emotional states and vocal characteristics is crucial in psychotherapy.
    • Objective measures are needed to quantify affect during therapeutic sessions.

    Observation:

    • Emotional intensity (fear, anger, depression, total affect) was rated in real-time during psychotherapy sessions.
    • Voice samples were analyzed for frequency and power spectral characteristics.

    Findings:

    • Significant correlations were found between specific voice spectral variables and rated emotional states.
    • Voice measures successfully predicted levels of anger, fear, depression, and total affect.
    • Distinct vocal patterns differentiated between various emotions and conflict epochs.
