Delta=Post−Pre. Statistical comparisons were performed using the Mann–Whitney U test (two-tailed). Effect size is Cliff’s delta (δ).
AP, aerodynamic power; PAP, peak air pressure; EAD, expiratory airflow duration; PEA, peak expiratory airflow; PT, phonation time; MPAP, mean peak air pressure; MADV, Mean Airflow During Voicing; AE, aerodynamic efficiency; MSDV, mean SPL during voicing; EV, expiratory volume; MEA, mean expiratory airflow; AR, airway resistance; F0, fundamental frequency; NHR, noise-to-harmonics ratio; CPP, cepstral peak prominence; L/H ratio, low-to-high spectral ratio.
