Measurement of speech disfluency through magnitude estimation and interval scaling.

The purpose was to assess whether equal-appearing interval or magnitude-estimation scaling resulted in a data set with a closer correlation to the physical stimuli, made up of speech samples with varying amounts of disfluency. 20 young adults completed two tasks. In Task 1, subjects used a 7-point equal-appearing interval scale to rate the disfluency of 10 speech samples having varying within sentence pause, presented randomly at 65 dB SPL.

Possible influence of linguistic musical background on perceptual pitch-matching tasks: a pilot study.

Linguistic background has been identified as important in the perception of pitch, particularly between tonal versus nontonal languages. In addition, a link between native language and the perception of musical pitch has also been established. This pilot study examined the perception of pitch between listeners from tonal and nontonal linguistic cultures where two different styles of music originate.

Effect of phonetics training on lingual awareness.

This investigation assessed the effect of phonetics training on lingual awareness in normal adult speakers of English. The study also compared Trained subjects' scores from a study in 2000 by Lohman and Fucci to subjects' posttraining scores in this investigation. Subjects were 36 students (M age=19.

Perceptual judgment of voice pitch during pitch-matching tasks.

This study investigated the perceptual judgment of voice pitch. 24 individuals were assigned to two groups to assess whether there is a difference in perceptual judgment of voice pitch during pitch-matching tasks. Group I, Naïve listeners, had no previous experience in anatomy, physiology, or voice pitch-evaluation methods.

Relationship between phonemic and lingual awareness.

The purpose of this preliminary investigation was to assess the relationship between knowledge of speech sounds (phonemes) and lingual awareness in normal adult speakers of English. The study also examined subjects' descriptions of lingual contact. 36 subjects (M age=19.

College-age males' ability to produce the acoustic properties of an aging voice.

The purpose of this study was to examine college-age males' ability to produce the acoustic properties of the normally aging voice when reading. The 17 subjects (M age=21.13 yr.
