Experimental phonetics

stress to determine how primary stress, secondary, and stressed syllables are

phonetically distinguished from each other and from unstressed syllables.

Gordon (2004) notes that many aspects effect phonological analysis of stress

prominence in a language, e.g., speaker’s intonational aspect in the utterance,

syllable structure, and morphology, therefore acoustic analysis acts as a tool for

examining stress and facilitates factors that help the syllable to be prominent.

While many researchers of phonetics and phonology have given various

definitions on stress, the present study refers to stress as the prominence of the

syllable as compared to adjacent syllables at the lexical level. Stress is a relative

factor, unlike aspects such as vowel quality, place, and manner features.

In addition, the part of speech production in which the stressed syllable is more
