Table 2: Comparison of fundamental frequency (F0 in Hz), maximum phonation duration (MPD in seconds), and formant frequencies (F1 and F2 in Hz) between esophageal, tracheoesophageal and normal laryngeal modes. In the table along with the individual data, the median and inter-quartile range values are also given for each mode of speaking. In the table the MPD and formant frequency values are provided for each vowel separately
