Using Innovative Acoustic Analysis to Predict the Postoperative Outcomes of Unilateral Vocal Fold Paralysis

Figure 2

Voice signals processed by LP. Example of the raw recorded voice from one patient before, 1 month after, and 3 months after lipoinjection (a, c, e). The corresponding glottal source waves (GSWs) estimated by LP (b, d, f). By inspection, the postoperation glottal source waveforms (d, f) have more regular periodicity than the preoperation (b).
