Abstract:
The study of the influence of flu and cough disease of men and women on their voice spectrum had been carried out. The sample voices were recorded by using a computer equipped with a software called “Praat” as a substitute for spectrum analyzer. The samples were selected for three boys and three girls at the age of 7-11, three females and three males at the age of 22-24 in the condition of normal and sick (flu and cough). There are three pieces of voices that has to be spoken by the sample, namely “Jurusan Fisika”, “Tetap Maju”, and “Selamat Sore”. In order to obtain a better result of the study, it is necessary for the sample to say the three pieces of voices in three times. The results show that the value of the fundamental frequency for the women is higher than that of the men either in normal (well) condition or unwell condition. The value of the fundamental frequency for children in unwell condition is around 276 Hz and 249 Hz for female and male respectively and for adult is 182 Hz for female and 143 for male. While the value of the fundamental frequency sample in the normal condition for children is 269 Hz for female and 252 Hz for male, for adult is 175 Hz for female and 130 Hz for male. The results also shows that the average value of format F1, F2, and F3 for males is higher compared to that for women in both conditions. Furthermore, the time duration for the three pieces of voices is longer for children compared to that for adult, while the time duration for the three pieces of voices for the samples in normal condition is shorter compared to that of unwell condition
