Acoustic Comparison between Tele-recorded Voice and Real-time Voice for the Sample of Sentences in Individuals with Typical and Pathological Voice Paired t-test
| Acoustic parameters | Participants with typical voice | Participants with pathological voice | ||
|---|---|---|---|---|
| Test statistics | p value | Test statistics | p value | |
| FO | 0.92 | 0.38 | 1.12 | 0.29 |
| Shimmer | 0.90 | 0.38 | 3.56 | 0.00** |
| HNR | 5.27 | 0.00** | 3.27 | 0.01* |
| CPPS | 2.24 | 0.05 | 1.14 | 0.28 |
| AVQI | 3.60 | 0.00** | 3.47 | 0.00** |
Note. F0 = Fundamental frequency, HNR = Harmonic to noise ratio, CPPS = Cepstral peak prominence smoothed, AVQI = Acoustic voice quality index.
