| Preaspiration, i.e. [hC], is a rare feature of stop production in the world’s languages that has been recently found to occur in Sienese Italian. We present a qualitative acoustic-phonetic description of voiceless geminate stops /p: t: k:/ with preaspiration that occurred in a corpus of spontaneous Sienese Italian speech (6 ss). We outline the different fine-grained realizations of preaspiration and discuss the findings in the context of our general knowledge of the phenomenon across languages | |

LEARNABILITY OF LARYNGEAL ABDUCTION IN VOICELESS FRICATIVES: CROSS-LINGUISTIC EVIDENCE

| Previous research of laryngeal-oral gestural co-ordination in vowel-voiceless fricative sequences (Vf) shows that earlier timing of glottal opening relative to oral constriction is a language-independent aerodynamic property. In this paper, we provide evidence that the extent of this gestural dissociation is nonetheless learnable in a variety-specific way, and is, thus, actively controlled. This study shows that in some British English varieties, large temporal laryngeal-oral dissociation in Vf transitions is a correlate of the fricative /voice/ contrast, while the dissociation is much tighter in a language neutralising /voice/ such as Russian. The learnability of Vf-gestures is important in the context of theories on gestural phonology and acoustic multidimensionality of the /voice/ contrast. | |

| Some fundamental questions concerning voice production remain unanswered despite numerous research approaches in various fields of voice science. It is widely believed that high intraglottal pressures may cause organic voice disorders – like vocal fold nodules or contact granulomas. This hypothesis seems reasonable but is difficult to prove given the challenges of pressure measurement and of establishing a causative link to disease. In this study we present a method for intraglottal contact pressure measurement in humans with a specially designed subminiature sensor. While implementing the measurement of the contact pressures, videolaryngoscopy is simultaneously used for online-monitoring. The new generation of subminiature sensors now allows us to make pressure measurements along the membranous vocal fold. We demonstrate contact pressure values for 10 healthy female and 10 healthy male subjects as well as for 10 patients with organic voice disorder. A video with endoscopic pictures illustrates the investigation procedure and data collection. | |
