Summary
Objective
To analyze the values of the fundamental frequency obtained through acoustic, electroglottographic,
and accelerometer assessments on the skin of the neck in individuals with and without
vocal alterations.
Methods
This was an observational cross-sectional study carried out at the Voice and Biomechanical
Outpatient Clinic of the Federal University of Minas Gerais, approved by the Research
Ethics Committee (study number 1,229,521). The nonprobabilistic sample consisted of
30 women (normal vocal quality, 15 and dysphonia, 15) aged 18–36 years (mean, 26.1
years) and 20 men (normal vocal quality, 15 and dysphonia, 5) aged 19–48 years (mean,
28.6 years). Subjects sustained a comfortable /ɑ/ with data captured by microphone,
with electrodes on thyroid cartilage, and from accelerometer above the thyroid cartilage.
Results of fundamental frequency extraction were compared between acoustic microphone
vs electrodes vs accelerometer for each subject.
Results
Regarding the fundamental frequency, we observed a difference in the values estimated
using the microphone and accelerometer, when compared to the values estimated by the
electrodes, in the dysphonic and nondysphonic female groups and among nondysphonic
men. The mean fundamental frequency found for normal voices was 195.8 Hz for female
voices and 112.0 Hz for male voices obtained through the microphone and accelerometer.
The values estimated using the electrodes were 209.6 Hz for female voices and 160.5
Hz for male voices. For dysphonic voices, the values were 187.7 Hz for female voices
and 126.8 Hz for male voices obtained through the microphone and accelerometer. The
values estimated using the electrodes were 226.8 Hz for female voices and 173.8 Hz
for male voices.
Conclusion
The fundamental frequency values estimated using the microphone and accelerometer
showed perfect correlation; however, the values estimated by the electrodes differ
from them.
