The purpose of the this study was to establish preliminary data on the characteristic of dysfluency in monologue. The subjects were 30 normal speaking adults(15 males and 15 females), aged from 18 to 30 and 30 normal speaking children, aged from 8 to 10. This study attempted to sample 1-minute portion of talking about the daily routine. Videotapes were made to analyze his/her speech sample in terms of the patterns and the frequency of dysfluency. The result of the present study were a follows: (1) The children had total dysfluency type ratios of 12.48%, dysfluency type ratios of 2.83%. Interjection was the most frequently occuring, followed by revision, incomplete phrase. (2) The adults had total dysfluency type ratios of 8.51%, dysfluency type ratios of 0.59%. Interjection was the most frequently occuring, followed by revision, syllable repetition. (3) In adults, both total dysfluency type ratios and dysfluency type ratios differed significantly by the gender. (4) Both total dysfluency type ratios and dysfluency type ratios differed significantly between adults and children.

The purpose of this study was to assess the speech rate, fluency and the type of dysfluencies of normal adults in order to provide a basic data of normal speaking. The number of subjects of this study were 30(14 females and 16 males), and their ages ranged 17 to 36. The rate was measured as syllables per minute (SPM). The speech rates in reading ranged 273-426 with a mean of 348 SPM and in speaking ranges 118-409 (mean=265). The average of their fluencies was 99.1% in reading and 96.9% in speaking. The rater reliability of speech rate in the data assessed by video was very high (r=0.98) and the rater reliability of speech fluency was moderately high (r=0.67). The disfluency types were also analysed from 150 disfluency episodes. Syllable repetition and word interjection were the most common disfluent types.

This study investigated the acoustical characteristics of phonatory offset-onset mechanisms. And this study shows the comparative results between non-stutterers (N=3) and a stutterer (N=1). Phonatory offset-onset means a laryngeal articulatory in the connected speech. In the phonetic context V_V), pattern 0(there is no changes) appeared in all subjects, and pattern 4(this indicate the trace of glottal fry and closure in spectrogram)was only in a Stutterer. In high vowels(/i/, /u/), pattern 3 and 4 appeared only in a stutterer. Although there is no common pattern among the non-stutterers, individual's preference pattern was founded. This study offers the key to an understanding of physiological movement on a block of stutter.
