The present study basically conducted a qualitative-oriented research to identify the articulating and listening problems of eleven AE vowels for Taiwanese eighth graders. It aimed to examine the relationship between production and perception of English vowels. Gender differences were probed under this sound pronunciation and discrimination framework. A vowel articulating test followed by a vow...

The development of clear speech was examined in a cross-sectional study of preschool children aged 3, 4, and 5 years old. Thirty children produced target monosyllabic words with monophthongal vowels in clear and casual speech conditions. Vowel acoustics were measured and adults were asked to provide clear speech ratings on either the vowel or the whole word. The results provided little evidence...

A miniature accelerometer and microphone can be used to obtain Horii Oral-Nasal Coupling (HONC) scores to objectively measure nasalization of speech. While this instrumentation compares favorably in terms of size and cost relative to other objective measures of nasality, the metric has not been well characterized in children. Furthermore, the measure is known to be affected by vowel loading, as...

PURPOSE The purpose of this study was to compare men with women in terms of speech intelligibility, to investigate the validity of objective acoustic parameters related with speech intelligibility, and to try to set up the standard data for the future study in various field in prosthodontics. MATERIALS AND METHODS Twenty men and women were served as subjects in the present study. After record...

Two experiments were conducted to evaluate the perceptual magnet effect. In Experiment 1, American English speakers representing diverse dialects were presented with a fine-grained set of stimuli (varying in just noticeable differences for F1 and F2) and indicated whether they heard "/i/" or "not/i/," thus delimiting the /i/ portion of the vowel space for individual subjects. Then these same su...

This study investigated the acoustic characteristics of voicing in English fricative consonants produced by anterior aphasics and the effects of phonetic context on these characteristics. Three patients produced voiced and voiceless fricative-vowel syllables in isolation, following a voiced velar stop, and following a voiceless velar stop. Acoustic analyses were conducted of the amplitude and p...

The purpose of this study was to acoustically examine the developmental characteristics of fundamental (f(0)) and formant frequencies (F1 and F2) in vowels produced by Korean male and female children in two age ranges (5 and 10 years of age). The study also compared formant frequency values among Korean children with those from existing English data. Results revealed that f(0) and F1 and F2 dec...

PURPOSE The present study was designed to investigate the relation of formant transitions to place-of-articulation for stop consonants. A speech production model was used to generate simulated utterances containing voiced stop consonants, and a perceptual experiment was performed to test their identification by listeners. METHOD Based on a model of the vocal tract shape, a theoretical basis f...
