Adult Normative Data for the OMNI-Vocal Effort Scale (VES).

Abstract

To establish normative values for the OMNI-Vocal Effort Scale (VES) in healthy adults without voice complaints. Secondary objective is to determine if there are differences in perceived vocal effort across age groups and between sexes. Prospective data collection across groups. A nine-item survey was administered by speech-language pathologists with specialization in voice to consenting adults 18 years or older. Participants underwent an auditory perceptual evaluation of voice and answered questions regarding age, history of voice problems, history of voice surgery, smoking history and hearing loss. Participants were instructed to rate their perceived vocal effort in conversational speech using the OMNI-VES. Multivariant analysis was conducted. Two hundred and fifty-one participants were recruited. The majority of adults without voice complaints reported that producing conversational voice was within the "extremely easy" to "easy" range, 0-3 (92.4%). This study provides preliminary data for perceived vocal effort. The OMNI-VES may be a useful tool in understanding changes in perceived vocal effort as a result of treatment for voice disorders. Further normative data are needed between sexes, across the gender spectrum, and older adult populations. Future directions include examining the magnitude of difference between numeric values on the scale and use of the scale with other dysphonic populations. 3 Laryngoscope, 2024.
