  • The nasalance score measured by Nasometer is a supplementary data for the perceptually rated nasality by a trained speech pathologist. Because the nasalance score varies with speech material, a valid and reliable material should be developed for evaluating it. The objectives of the present study were (1) to examine whether phonetic contexts affect the nasalace score and (2) to examine the reliability of both meaningless one-syllable words and meaningful sentences. This study analyzed nasalance score in 20 different phonetic contexts from 24 normal adults. The results showed (1) nasalance score increased as the percentage of nasal consonants and vowel /i/ increased, (2) the manner and the place of articulation in oral consonants did not influence the nasalance score, and (3) in nasalance score, correlation between sentences was found to be high, but correlation between syllables was not. These results may indicate that, when preparing the speech material for measuring the nasalance score, it is important to consider not only the percentage of nasal consonants but also that of vowel /i/ in the speech material. In addition, the sentence is more reliable material than meaningless one-syllable words.

  • The purpose of this study was to obtain normative nasalance scores for adult subjects speaking the Korean language and to determine whether significantly different scores exist for female and male speakers. Mean nasalance scores were obtained for normal speaking Korean adults while they are reading vowels, consonants, no nasal sentence, mild nasal sentence, and high nasal sentence. Thirty adults who had lived in Seoul area with normal articulation, resonance, and voice were included. Among the subjects 15 were male aged 24-38 years and 15 were female aged 19-33. Nasometer data were collected and analyzed using the Kay Nasometer 6400. Nasalance scores were evaluated to investigate the effect of gender by using statistical tests. Nasalance data showed that nasalance values varied accroding to speech stimuli, and there was no significant difference in nasalance scores between male and female speakers in most of the language samples.
