TL;DR: This paper found that children produced vowel duration differences of the same nature and magnitude as those found in adult speakers' utterances, and that the duration of a preceding vowel and duration of voicing during the final consonant closure were reliable predictors of the voicing characteristic of final consonants.

TL;DR: In this article, an electrical analog of vocal tract aerodynamics was used to study the probable effects of place of articulation and syllable stress on closure voicing offset, allowing variation of subglottal pressure, glottal area, supralaryngeal cavity volume, wall mechanics, and oral constriction geometry.
Abstract: Voiced and voiceless stops in initial position are known to differ in Voice Onset Time; they may also differ in closure duration and the duration of closure voicing. Besides the voicing distinction, such factors as the position of the stop in a word or utterance, the stop's place of articulation, and the stress of adjacent syllables will also affect these measures. Data from the literature have been extended with new acoustic measurements for English, Swedish, and other languages. While there is some variation across languages, general patterns, which might be attributable to vocal tract physiology, can be identified. In an attempt to account for these patterns, an electrical analog of vocal tract aerodynamics can be used to study the probable effects of place of articulation and syllable stress on closure voicing offset. The model allows variation of subglottal pressure, glottal area, supralaryngeal cavity volume, wall mechanics, and oral constriction geometry. The extent to which these variables determi...

TL;DR: Acoustic analysis with AMPEX demonstrates that the most informative features are, for SV, the voicing-related acoustic features and, for AdSD, the perturbation measures.
Abstract: This article is a compilation of own research performed during the European COoperation in Science and Technology (COST) action 2103: 'Advance Voice Function Assessment', an initiative of voice and speech processing teams consisting of physicists, engineers, and clinicians. This manuscript concerns analyzing largely irregular voicing types, namely substitution voicing (SV) and adductor spasmodic dysphonia (AdSD). A specific perceptual rating scale (IINFVo) was developed, and the Auditory Model Based Pitch Extractor (AMPEX), a piece of software that automatically analyses running speech and generates pitch values in background noise, was applied. The IINFVo perceptual rating scale has been shown to be useful in evaluating SV. The analysis of strongly irregular voices stimulated a modification of the European Laryngological Society's assessment protocol which was originally designed for the common types of (less severe) dysphonia. Acoustic analysis with AMPEX demonstrates that the most informative features are, for SV, the voicing-related acoustic features and, for AdSD, the perturbation measures. Poor correlations between self-assessment and acoustic and perceptual dimensions in the assessment of highly irregular voices argue for a multidimensional approach.

TL;DR: This paper describes a phase vocoder based technique for voice transformation that provides a fle xible way to manipulate various aspects of the input signal, e.g., fundamental frequency of voicing, duration, energy, and formant positions, without explicit extraction.
Abstract: This paper describes a phase vocoder based technique for voice transformation. This method provides a fle xible way to manipulate various aspects of the input signal, e.g., fundamental frequency of voicing, duration, energy, and formant positions, without explicit extraction. The modifications to the signal can be specific to any feature dimensions, and can vary dynamically over time. There are many potential applications for this technique. In concatenative speech synthesis, the method can be applied to transform the speech corpus to different voice characteristics, or to smooth any pitch or formant discontinuities between concatenation boundaries. The method can also be used as a tool for language learning. We can modify the prosody of the student’ s own speech to match that from a native speaker, and use the result as guidance for improvements. The technique can also be used to convert other biological signals, such as killer whale vocalizations, to a signal that is more appropriate for human auditory perception. Our initial experiments show encouraging results for all of these applications.

Journal ArticleDOI
TL;DR: The authors examined the influence of post-vocalic voicing on vowel and closure durations in VCV and VCV sequences, and found that the effect of post vocalic voicing was not as consistent for unstressed vowels as for stressed vowels.
