Aging significantly alters vocal quality, affecting fundamental frequency (Fo) and leading to noticeable vocal changes in older adults. These spectroacoustic characteristics can help identify age and sex from voice patterns.

Area of Science:

  • Gerontology
  • Acoustic analysis
  • Speech science

Context:

  • Aging involves complex involutive processes affecting the respiratory, phonatory, and articulatory systems.
  • These changes lead to significant alterations in vocal quality, impacting speech production in the elderly.

Purpose:

  • To identify specific spectroacoustic parameters characterizing the senile voice.
  • To correlate these vocal characteristics with morphofunctional changes in the aging vocal apparatus.

Summary:

  • Spectroacoustic analysis revealed distinct electroacoustic features in the senile voice, including variations in fundamental frequency (Fo) and mean amplitude.
  • Observed deficits in vocal sustain and intensity, along with senile tremolo and cycle-to-cycle Fo alterations, were linked to anatomical and functional glottic changes.

Impact:

  • The study confirms that specific vocal patterns and speech quality in the elderly are reliable indicators for age and sex identification.
  • Findings contribute to understanding the aging voice and its potential for biometric applications.
