Repetitive Saliva Swallowing Test Classification
Tidsramme: Day 1
|
Classification of swallowing function based on the Repetitive Saliva Swallowing Test (RSST).
Participants will be classified as having normal RSST performance if they complete greater than or equal to 3 swallows in 30 seconds, and abnormal RSST performance if they complete fewer than 3 swallows in 30 seconds.

Tidsramme |
|---|---|---|
|
Eating Assessment Tool-10 Total Score
Tidsramme: Day 1
|
Total score on the Eating Assessment Tool-10 (EAT-10), a 10-item self-report questionnaire used to assess swallowing-related symptoms.
The total score ranges from 0 to 40, where higher scores indicate worse swallowing-related symptoms.
A score of 3 or higher suggests possible swallowing difficulty.
|
Day 1
|
|
Diadochokinetic Speech Rate
Tidsramme: Day 1
|
Rate of repeated diadochokinetic speech productions of /pa/, /ta/, and /ka/.
The rate will be reported as syllables per second.
|
Day 1
|
|
Diadochokinetic Speech Fundamental Frequency
Tidsramme: Day 1
|
Fundamental frequency (F0) extracted from repeated diadochokinetic (DDK) speech recordings of /pa/, /ta/, and /ka/.
Fundamental frequency will be reported in Hertz (Hz).
|
Day 1
|
|
Diadochokinetic Speech First Formant Frequency
Tidsramme: Day 1
|
First formant frequency (F1) extracted from repeated diadochokinetic (DDK) speech recordings of /pa/, /ta/, and /ka/.
F1 reflects the first resonance frequency of the vocal tract and will be reported in Hertz (Hz).
|
Day 1
|
|
Diadochokinetic Speech Second Formant Frequency
Tidsramme: Day 1
|
Second formant frequency (F2) extracted from repeated diadochokinetic (DDK) speech recordings of /pa/, /ta/, and /ka/.
F2 reflects the second resonance frequency of the vocal tract and will be reported in Hertz (Hz).
|
Day 1
|
|
Diadochokinetic Speech Jitter
Tidsramme: Day 1
|
Jitter extracted from repeated diadochokinetic (DDK) speech recordings of /pa/, /ta/, and /ka/.
Jitter reflects short-term cycle-to-cycle variability in fundamental frequency and will be reported as a percentage.
|
Day 1
|
|
Diadochokinetic Speech Shimmer
Tidsramme: Day 1
|
Shimmer extracted from repeated diadochokinetic (DDK) speech recordings of /pa/, /ta/, and /ka/.
Shimmer reflects short-term variability in voice amplitude and will be reported in decibels (dB).
|
Day 1
|
|
Diadochokinetic Speech Harmonics-to-Noise Ratio
Tidsramme: Day 1
|
Harmonics-to-noise ratio (HNR) extracted from repeated diadochokinetic (DDK) speech recordings of /pa/, /ta/, and /ka/.
HNR reflects the ratio of periodic harmonic energy to noise energy in the voice signal and will be reported in decibels (dB).
|
Day 1
|
|
Diadochokinetic Speech Root Mean Square Amplitude
Tidsramme: Day 1
|
Root mean square (RMS) amplitude extracted from repeated diadochokinetic (DDK) speech recordings of /pa/, /ta/, and /ka/.
RMS amplitude reflects the average acoustic energy of the speech signal and will be reported in normalized amplitude units.
|
Day 1
|
|
Diadochokinetic Speech Zero-Crossing Rate
Tidsramme: Day 1
|
Zero-crossing rate (ZCR) extracted from repeated diadochokinetic (DDK) speech recordings of /pa/, /ta/, and /ka/.
ZCR reflects the rate at which the speech signal changes sign over time and will be reported as the number of zero crossings per second.
