Abstract(s)

In this article, a statistical analysis of the Harmonic to Noise Ratio (HNR) parameter was performed using the boxplot tool in the SPSS software, using the Cured Database with 901 individuals (707 pathological and 194 control) to create relevant groups, enabling the automatic identification of these dysfunctions. We analyzed whether the HNR parameter for all control and pathological subjects were compared between various voice groups, gender, vowel, and tone, no difference in HNR can be considered between the male and female gender of healthy and pathological voices. Still, there are differences between the vowels and tones of each gender. Trends indicate that this parameter is a good resource for an intelligent diagnostic system, using the vowels /a/ and /u/ in high tones.
