The estimation of formant frequencies from acoustic speech signals is mostly based on Linear Predictive Coding (LPC) algorithms. Since LPC is based on the source-filter model of speech production, the formant frequencies obtained are often implicitly regarded as those for an infinite glottal impedance, i.e., a closed glottis. However, previous studies have indicated that LPC-based formant estimates of vowels generated with a realistically varying glottal area may substantially differ from the re...

Body-cover models of vocal folds made of silicone rubber are increasingly used in voice research. The very soft cover layer often shows a residual stickiness. This study explored potential methods to avoid the stickiness while maintaining the softness and a flat surface structure. Therefore, 60 silicone samples werefabricated from different silicones and with different manufacturing procedures tosimulate the compound of cover layer and epithelium layer. 30 silicone sampleswere tempered in differ...

This paper demonstrates by means of an example, how historic collections of universities can be utilized in modern research and teaching. The project refers to the Historic Acoustic-phonetic Collection (HAPS) of the TU Dresden. Two “guiding fossils” from the history of speech technology are selected to present a selection of results.
