Summary
Archival voice recordings reveal that the speaking fundamental frequency (SFF) significantly lowers with age in Australian women. This study highlights the value of historical audio data for aging voice research.
Area of Science:
- Gerontology
- Speech Science
- Acoustics
Background:
- Archival voice recordings offer a valuable, yet underutilized, resource for studying the aging voice.
- Historical sound collections provide speech pathologists and voice scientists with extensive data for research.
Purpose of the Study:
- To examine changes in speaking fundamental frequency (SFF) in Australian women over 50 years using archival recordings.
- To investigate the benefits and challenges of utilizing archival data in voice research.
Main Methods:
- Comparison of voice recordings from 1945 with recordings of the same Australian women made in 1993.
- Analysis of speaking fundamental frequency (SFF) changes over time.
Main Results:
- A statistically significant decrease in speaking fundamental frequency (SFF) was observed with increasing age in the studied group of Australian women.
- The findings demonstrate age-related vocal changes.
Conclusions:
- Archival data is a viable resource for longitudinal and cross-sectional studies on the aging voice.
- The results have implications for interpreting cross-sectional aging voice data.
- Further research utilizing archival voice data is recommended.
