ABSTRAK

Penelitian ini bertujuan untuk mengetahui pengaruh gangguan tenggorokan terhadap perubahan karakteristik suara yang diucapkan. Karakteristik suara pada penelitian dibatasi pada aspek pitch, formant, dan pola spektrum. Spektrum suara yang diamati dibatasi pada suara vokal /a/, /i/, /u/, /e/, dan /o/. Terdapat tujuh orang responden laki-laki yang berusia antara 35 sampai 50 tahun. Rekaman dilakukan saat kondisi sehat dan saat kondisi terjadi gangguan di tenggorokan. Dari hasil analisis diperoleh bahwa secara umum 71,4% perubahan pitch terjadi ke arah frekuensi yang lebih rendah, sedangkan 25,7% ke arah frekuensi yang lebih tinggi, dan sisanya tidak mengalami perubahan pitch. Berdasarkan analisis formant diketahui bahwa perubahan susunan formant paling nampak pada bunyi huruf /a/ sedangkan pola paling tidak berubah ditemukan pada bunyi huruf /i/. Selanjutnya dengan menggunakan cross-korelasi diperoleh bahwa perubahan terbesar pola spektrum frekuensi terjadi pada ucapan huruf /a/.

Kata kunci: formant, pitch, spektrum, suara, vokal

 

ABSTRACT

The aim of this research is to determine the effect of sore throat on changes of speech characteristics. The sound characteristics in this research are limited to pitch, formant, and spectrum pattern. The observed sounds is limited to the vowel sounds /a/, /i/, /u/, /e/, and /o/. There are seven male respondents of 35 to 50 years old. A sound characteristic change is obtained by comparing the pitch, formant and spectrum pattern in the healthy condition and the sore throat conditions. The change is grouped in two categories i.e. shifting into the lower frequency and shifting to the upper frequency. From the analysis obtained that, in general, 71.4% of pitches are shifted to lower frequencies, while 25.7% shifted to higher frequencies, and the rest does not change. From the formant analysis, the largest change of formant pattern occurs in the sound of vowel /a/ while the smallest change is in vowel /i/. Furthermore, using cross correlation, the change of the pattern is derived. The cross-correlation result shows that vowels /a/ is the most suffering pattern due to the sore throat.
