PMID 41499449WHAT IT FOUND
A four-session voice education program improved older adults' knowledge of vocal hygiene, with gains maintained one year later.
Participants reported applying practices like drinking more water and reducing voice volume, though memory issues and habit-breaking remained barriers for some.
Key findings
01Voice care knowledge scores increased significantly immediately after training and remained significantly higher than baseline at 1-year follow-up.
02Participants reported implementing vocal hygiene practices such as drinking more water, avoiding spicy foods, and reducing voice volume in daily life.
03Memory retention and lack of motivation were identified as primary barriers to maintaining voice care practices, with requests for follow-up revision sessions.

What it does not show
No control group was included, so improvements cannot be definitively attributed to the program rather than time or testing effects. The study relied on self-reported knowledge and attitudes rather than objective acoustic or perceptual voice measures. The sample was small (n=34 analysed) and recruited from community centres, limiting generalisability. No screening for voice disorders was conducted, so participants' baseline voice health status is unknown.
Declared interests
The authors declared no competing interests.
The easy way to misread this
Do not interpret this as evidence that voice education improves voice quality or acoustic parameters. The study measured knowledge and self-reported behaviours, not actual voice production, and lacked a control group to rule out placebo or natural variation effects.
