A new descriptive framework for voice quality perception (Kreiman, Gerratt, Kempster, Erman, & Berke, 1993) states that when listeners rate a voice on some quality dimension (e.g., roughness), they compare the stimulus presented to an internal standard or scale. Hypothetically, substituting explicit, external standards for these unstable internal standards(More)
PURPOSE Many researchers have studied the acoustics, physiology, and perceptual characteristics of the voice source, but despite significant attention, it remains unclear which aspects of the source should be quantified and how measurements should be made. In this study, the authors examined the relationships among a number of existing measures of the(More)
To enable differences in modes of glottal vibration to be studied, glottal air volume velocity waveforms can be recovered from speech recordings by inverse filtering. Most previous published work in this area has made use of analog filters. Digital inverse filters offer many advantages, including the ability to change filter settings to match changing vocal(More)
Voice quality is an important perceptual cue in many disciplines, but knowledge of its nature is limited by a poor understanding of the relevant psychoacoustics. This article (aimed at researchers studying voice, speech, and vocal behavior) describes the UCLA voice synthesizer, software for voice analysis and synthesis designed to test hypotheses about the(More)
Pathological voices are particularly difficult to inverse filter and fit with source models, in part, because of source-tract interactions inherent in these voice types. In order to obtain good synthetic copies of these voices, we need to know the practical importance of accurately inverse filtering and modeling individual voice sources. To this end, thirty(More)
This paper describes a computer assisted method of teaching profoundly deaf children to speak, which employs the unique feature of an integrated text-to-speech system (TTS). Our earlier speech training system presented a series of speech parameters, derived from articulatory instruments and acoustic analysis, in a visual form. In that system, teacher's(More)
