The Effects of Stress Type, Vowel Identity, Baseline f(0), and Loudness on the Relative Fundamental Frequency of Individuals With Healthy Voices

摘要

Objective. Relative fundamental frequency (RFF) has been investigated as a possible acoustic measure to assess laryngeal tension. This study aimed to identify possible factors in RFF stimuli (stress type, vowel identity, baseline f(0), and loudness) that might also affect RFF values.
