“…Currently, the FEM is almost exclusively used for analysing the acoustic characteristics of VT, the computation complexity of which increases with the number of finite elements used, which discredits the examined volume of the acoustic system. Direct geometric reconfiguration at the level of the finite element mesh represents a very complex problem, which requires a detailed analyses of the derived model [8]. However, due to the computation demands, such models are oftentimes not suitable for subsequent optimization tasks, whose aim it is to finetune the acoustic characteristics of phonation to the required parameters.…”

In order to examine the impact of geometric configuration of the human vocal tract on the redistribution of acoustic energy in the frequency spectrum, it is necessary to assemble computation models, which facilitate simple modification of the model’s geometric characteristics. This article describes how the human vocal tract model was constructed using so-called super-elements using the improved reduced system method. The mentioned procedure allows using such a model for demanding optimization calculations, for which the model is modified on the super-element level. Furthermore, the article presents an alternative approach, in which an isoparametric element of a higher degree polynomial was derived. Both approaches were compared and used to find the geometric configuration of the human vocal tract amplifying acoustic energy values on the frequency spectrum to around 3kHz.

“…Building upon this initial work, a following study emphasised the importance of accurately simulating higher-order modes to achieve expressiveness [11], especially for tense phonations and high fundamental frequencies. Additionally, the manipulation of the vocal tract characteristics using simulations based on finite element methods (FEM) has enabled the production of effects such as the singing formant in 3D-based articulatory voice generation [12]. Therefore, from these works, it can be concluded that, for the production of expressive speech, a proper model and adjustment of the vocal tract response and the glottal source signal is of paramount importance, as is considering their varying relevance depending on the target speaking style [13,14].…”

Current articulatory-based three-dimensional source–filter models, which allow the production of vowels and diphtongs, still present very limited expressiveness. Glottal inverse filtering (GIF) techniques can become instrumental to identify specific characteristics of both the glottal source signal and the vocal tract transfer function to resemble expressive speech. Several GIF methods have been proposed in the literature; however, their comparison becomes difficult due to the lack of common and exhaustive experimental settings. In this work, first, a two-phase analysis methodology for the comparison of GIF techniques based on a reference dataset is introduced. Next, state-of-the-art GIF techniques based on iterative adaptive inverse filtering (IAIF) and quasi closed phase (QCP) approaches are thoroughly evaluated on OPENGLOT, an open database specifically designed to evaluate GIF, computing well-established GIF error measures after extending male vowels with their female counterparts. The results show that GIF methods obtain better results on male vowels. The QCP-based techniques significantly outperform IAIF-based methods for almost all error metrics and scenarios and are, at the same time, more stable across sex, phonation type, F0, and vowels. The IAIF variants improve the original technique for most error metrics on male vowels, while QCP with spectral tilt compensation achieves a lower spectral tilt error for male vowels than the original QCP.
