In this research, a new comparison criterion was proposed to study properties of the
audio signal for each of the varieties of smokers and non-smoking persons. For this
purpose, a database for smokers has been created. The smoker database contains
12 Syrian
native speakers, six of them were smokers and the others were non-smokers. The smokers
had been smoking for more than 10 years. All speakers were men and their ages ranging
between 35 and 42 years old. They live in rural towns and speak the same dialect.
Syrian vowels can be classified into long vowels and short ones. The long vowels are
/AA/, /UU/, /II/ pronounced as ([ ي, و, ا ]) and the short vowels are /A/, /U/, /I/ pronounced
as ([ كسرة, ضمة, فتحة ]). In this study, the Speakers have to pronounce the following sentence
/I love Syria/ pronounced as ([ أَنَاْ أَحَبُّ سُوْرِيْة ]), and it was spoken during three hours. This
sentence is rich with vowels.
For each speaker, a long vowel triangle in ten planes and a short vowel triangle in ten
planes as well were generated and analyzed. A new criterion was suggested to determine
the most suitable vowel triangle for smoker distinction. This criterion depends on
calculating the different distances among all centers of vowel triangles in each plane and
determining the minimal distance called d. For each plane, the most suitable vowel triangle
had been set as AIU35 short vowel triangle and AAIIUU45 long vowel triangle.
