Detection of relevant changes in the speaking voice of women measured by the speaking voice profile

Abstract

A healthy voice serves us as a basis for communication and an indispensable tool in a modern society with a growing number of vocal-intensive professions. There are indications that the average frequency of the speaking voice of women has decreased in recent years and is approaching that of men in the sense of sociophony. An epidemiological prospective cohort study will investigate the influences of age, personality traits and socio-demographic factors on the speaking voice of women. Within the framework of a standardized examination procedure, the speaking voice of 2478 voice-healthy female participants between 5 and 83 years of age was registered in 4 different intensity levels (softest voice, conversational voice, classroom voice and shouting voice). Subsequently, the collected values for frequency and loudness of the different intensity levels were examined for correlation with age and results from questionnaires on personality (FFFK and BFI-10), on (mental) health (Patient-Health-Questionnaire - PHQ) and on socio-economic status (SES). Significant age-related influences on the speaking voice could be demonstrated for all voice intensities. For the personality traits investigated, significant positive correlations between the volume of the calling and speaking voice and extraversion were found. For the frequency of the softest voice and speaking voice, significant correlations were found for the personality traits of extraversion and tolerance. While no significant associations were found between the voice parameters of the speaking voice and the PHQ, it was found that the SES has a significant influence on both frequency and intensity. In addition to age-related changes, relevant influences of personality traits and the SES on speaking voice parameters in women were confirmed, which should be considered in clinical care of dysphonia.
