| Measures | CPPS | HNR | HL Ratio | Breathiness |
|---|---|---|---|---|
| CPPS | 1.00 | .80* | −.61* | −.83* |
| HNR | 1.00 | −.76* | −.77* | |
| HL ratio | 1.00 | .45 | ||
| Breathiness | 1.00 |
Note. CPPS = smoothed cepstral peak prominence; HL ratio = high-to-low spectral ratio; HNR = harmonics-to-noise ratio.
