Abstract:

Speech sounds have an essential role in audiology as sound signals in the evaluation of

hearing. They have many functions in diagnosing and determining the type and degree of

hearing loss, and then assessing the efficiency of hearing aids or cochlear implants and

evaluating hearing performance in noise. Each language has both suprasegmental and

segmental characteristic features related to its own and the language family it belongs. The

studies so far, in general, have focused on the segmental characteristic features. This should

be taken into account by all scientific fields in which the language on the sense of the

suprasegmental structure has an impact. The most comprehensive suprasegmental unit is

stress in the meaning of affecting the variables of speech, such as intensity, duration, and

frequency. Determination of the acoustic differences in stress in monosyllabic words is

important in many fields, especially in audiology tests using speech sounds, as well as

linguistics and sound engineering. Therefore, in this study, using consonant-vowelconsonant

(CVC) format, voices of 50 male subjects were recorded. Each word contained

the same phonemes and also has a meaning in the reversed order. The subjects, with normal

hearing, voice and speech functions, were aged between 18-65 and spoke Contemporary

Turkey Turkish. As a result of the analysis and statistics, it was found that the intensity,

duration, and frequency changes occurred in the single syllable words in CVC format with

the effect of stress according to the position of the consonants (whether initial or final). Our

results show that the consonant phonemes of single-syllable words in the CVC format, which

are most commonly used in speech discrimination tests, cause changes that affect the

outcome of the tests.
