The median values for frequencies of the first, second, and third formants of the consonant measured as 262, 1255, and 2418 Hz for the men, and 279, 1425, and 2444 Hz for the women the values for consonants were 270, 1546, and 2507 Hz for the men, and 295, 1690, and 2794 Hz for the women. Using the Praat program, we measured the acoustic features of the nasal consonants, including fundamental frequencies, formant and antiformant frequencies, spectral slope parameters, durations and amplitudes, and formant transitions on adjacent vowels. Ten volunteers (five males and five females) each read the list, and we recorded them. We prepared a list of 28 single or two-word terms for this study. This study aims to establish the acoustic properties of Turkish nasal consonants, develop a method to demonstrate the presence of “the palatal n”, and establish a reference source for evaluating speech problems related nasal consonants. “The palatal n” (/ŋ/), which occurs in some Anatolian dialects, is not a separate phoneme rather, it is an allophone of the consonant /n/. In Turkish, there are two nasal consonants that act as a phoneme: the bilabial consonant /m/ and the alveolar (or dental) consonant /n/. Acoustically, they are like vowels, but one can differentiate them from vowels by their lower energy. Nasal consonants are speech sounds that involve the nasopharyngeal and nasal cavities in the vocal tract during articulation. The Acoustic Characteristics of Nasal Consonants in Turkish
