Speech fluency: effect of age, gender and context

Area of Science:

• Speech-Language Pathology
• Gerontology
• Linguistics

Background:

• Investigating age-related changes in speech production is crucial for understanding communication in older adults.
• Previous research has yielded mixed results regarding the impact of age, gender, and task demands on speech fluency.

Purpose of the Study:

• To analyze the effects of age, gender, and speaking task on speech fluency in older adults (55-92 years).
• To compare speech fluency performance between different age groups of older adults and a younger control group.
• To explore the relationship between speech fluency and speech rate in older talkers.

Main Methods:

• Speech fluency was assessed in 78 older adults across three speaking conditions.
• Participants were grouped by age, and results were compared to a younger control group (25-35 years).
• Statistical analyses identified significant differences (p < or = 0.01) related to age, gender, and task.

Main Results:

• Few significant effects or interactions were observed for age, gender, or task on speech fluency.
• Speech rate performance generally mirrored the findings for speech fluency.
• Older adult groups showed limited significant differences when compared to each other or the younger control group.

Conclusions:

• Age, gender, and task appear to have minimal impact on speech fluency in the studied older adult population.
• The findings suggest relative stability in speech fluency and rate across older age groups under the tested conditions.
• Further research is needed to explore potential subtle influences and compare these results with existing literature.
