Associations of Sex Hormones and Anthropometry with the Speaking Voice Profile in the Adult General Population.
LIFE Adult

Abstract (Expand)

OBJECTIVE: There is evidence that sexual hormone concentrations and anthropometric factors influence the human voice. The goal of this study was to investigate to what extent body mass index (BMI), … body height, body weight, breast-to-abdomen-ratio, testosterone, estradiol, dehydroepiandrosterone-sulfate (DHEA-S), follicle-stimulating hormone, and luteinizing hormone are associated with the sound pressure level and the fundamental frequency of the speaking voice in a cross-sectional approach among adults in the general population. METHODS: Speaking voice profiles with four different intensity levels, hormone concentrations, and anthropometric parameters were assessed for 2,381 individuals aged 40-79 years, who were randomly sampled from the population of a large city in Germany. Multivariate analysis was performed, adjusting for age and stratified by sex. RESULTS: Taller body height was associated with lower frequencies. Higher body weight was associated with lower frequencies and higher sound pressure levels. The ratio of chest to abdominal circumference was associated with the sound pressure levels in males and females: participants with larger breast-to-abdomen-ratio were found to have higher sound pressure levels. Among the sexual hormones, higher concentrations of DHEA-S were associated with lower fundamental frequencies of the voice while using the normal speaking voice. In addition, bioavailable testosterone was associated with the sound pressure level of the normal speaking voice in men and the softest speaking voice in women. CONCLUSION: Our findings suggest that BMI, body height, body weight, breast-to-abdomen-ratio, bioavailable testosterone, and DHEA-S are associated with the speaking voice in adults. No associations between testosterone and the frequency of the speaking voice were found.

The Speaking Voice in the General Population: Normative Data and Associations to Sociodemographic and Lifestyle Factors.
LIFE Adult

Abstract (Expand)

OBJECTIVES: Normative data concerning the speaking voice in the general population were gathered with the aim to establish standard values for clinical diagnostics. Associations between the speaking … voice and sociodemographic factors were examined. STUDY DESIGN: This is a prospective cross-sectional population-based study. METHODS: Speaking voice profiles were measured for 2472 (1154 male and 1318 female) participants between the ages of 40 and 79 years, using four speaking voice intensity levels: softest speaking voice (I), conversational voice (II), classroom voice (III), and shouting voice (IV). Smoking status and socioeconomic status were assessed. Data were analyzed using multivariate regression. RESULTS: The mean voice frequencies were 111.8 Hz for male and 161.3 Hz for female participants (I), 111.9 Hz for male and 168.5 Hz for female participants (II), 130.2 Hz for male and 198.0 Hz for female participants (III), and 175.5 Hz for male and 246.2 Hz for female participants (IV). Frequencies increased significantly with age for male but not for female participants. Sound pressure levels rose significantly with age at intensity levels I-III for both sexes, but decreased at intensity level IV. Frequencies and sound pressure levels were similar between nonsmokers and former smokers. Current smokers showed significantly lower frequencies as opposed to non- and former smokers. Speaking voice range and dynamics increased with higher socioeconomic status. CONCLUSIONS: The data are suitable as age-adjusted normative values for clinical measurement of the speaking voice. The mean fundamental speaking voice frequency of female participants was six to seven semitones lower than previously described.
