Sustained vocalizations of vowels [a], [i], and syllable [mə] were collected in twenty normal-hearing individuals. On vocalizations, five conditions of different audio-vocal feedback were introduced separately to the speakers including no masking, wearing supra-aural headphones only, speech-noise masking, high-pass noise masking, and broad-band-noise(More)
PURPOSE The purpose of this study was to explore the formant-articulation relationships in corner vowels by acoustic analysis of speech signals and measuring tongue contour using ultrasonography. METHOD Eighteen healthy adults (8 men, 10 women), aged between 20 and 40 years, were enrolled. Speech signals of sustained vowels /ɑ/, /i/, and /u/ were recorded(More)
To investigate the audio-vocal feedback responses of (F0) to hearing amplification in severe-to-profound prelingual hearing loss (SPHL) using power spectral analysis of F0 contour of sustained vowels. Sustained phonations of vowel/a/of seventeen participants with SPHL were acquired with and without hearing-aid amplifications. The vocal intensity was(More)
