Phonation sample of vowel /a/ for 6 seconds, thrice, measurement of throat temperature and a self-rating questionnaire was collected as baseline. Participants were provided with an English novel and were instructed to read at 70-80 dB SPL for 45 minutes. Fundamental frequency, throat temperature and scores from the self-rating questionnaire were compared between pre-reading and post-reading conditions. Entire experiment was carried out in an air-conditioned room at 25 ℃.Results: Statistically significant difference was observed within groups for fundamental frequency, throat temperature and scores of self-rating questionnaire. However, statistical significance was seen only in fundamental frequency and self-rating questionnaire. Conclusion: This study describes the potential use of thermal imaging to be used alongside other measures (acoustics) in assessing vocal load.
