| Popis: | According to current research, both age and cognitive decline have an effect on speech rate. While healthy elderly speakers are reported to speak at a slower rate than their younger counterparts, it has also been noted that elderly patients with a cognitive decline speak more slowly than their healthy elderly peers. This study analyzes the speech rates of healthy elderly speakers and compares the results with our previously reported data from speakers diagnosed with dementia. Our healthy elderly participants repeated five-syllable carrier phrases with varying target words. The durations of consonant and vowel segments will be measured using digital spectrograms to determine the extent of final lengthening, compensatory shortening, and overall speech rate (in syllables and second). Results for the two speaker groups will be compared with each other and also with results previously reported in the literature. |
