PURPOSE: To investigate the possible existing correlations between trait anxiety, state anxiety, and vocal parameters. METHODS: Participants were 24 adult subjects, 12 men and 12 women, with ages between 19 and 42 years, with no psychiatric history. The score in the State-Trait Anxiety Inventory (STAI), especially the STAI-Trait, enabled the division of participants into two groups: low anxiety (LA) and high anxiety (HA). Psychological parameters (STAI) and vocal parameters (self-assessment through the vocal signs and symptoms questionnaire and the Voice-Related Quality of Life - V-RQoL protocol; perceptual, auditory and visual assessment of vocal behavior with the description of voice, speech and body parameters; and acoustic analysis). The sustained production o the vowel /a/, counting numbers, and a discourse regarding the subjects' greatest anxiety moments constituted the analyzed material. RESULTS: The higher the trait anxiety indicated by STAI, the greater the evidence of anxiety in connected speech and discourse; the higher the vocal pitch, the greater the impairment in speech articulation, coordination between breathing and speech, body movement and facial expression. The higher the state anxiety, the greater the evidence of anxiety in various parameters of the speech, with imbalance in vocal resonance, alterations in the modulation and articulation of speech and in facial expression. CONCLUSION: The trait and state of anxiety differentiated the communicative behavior of individuals, involving changes in the body, speech and voice.
