“…Our results relate to Brazilian Portuguese speakers, and the linguistic variations associated with the language's cultural standards may also affect speech and voice patterns. Those factors combined may lead to significant differences in the acoustic electroglottographic findings of speakers of different languages 6 . More electroglottographic research using different software programs and looking into other languages is needed to allow for a better understanding of these variables and, consequently, to improve the analyses of these values in subjects with speech and laryngeal disorders.…”

“…It is equipped with a series of sensors to measure these parameters, and thus offers improved diagnostic capabilities and enhanced patient follow-up in terms of surgery, drug therapy, and phototherapy outcome 5 . Acoustic analysis software for speech and voice differ in the way they calculate acoustic parameters, and the outcome of the measurements may be affected by linguistic variations stemming from language cultural patterns 6 . Results also vary depending on the recording instrumentation, ambient noise, gender or age of the speaker, which shows that the quality of the equipment used to record patient voice, the type of software, and the anatomical-functional of the larynx may affect measurements in the short run 1 .…”

Objective: This paper aims to define the mean values for electroglottography tests of Brazilian Portuguese speakers on EVA. Materials and Method:The voices of 20 men and 20 women without voice-related complaints were analyzed through electroglottography so as to obtain reference values for normality. Case study: this is a descriptive cross-sectional study. Results:The mean values for normal male voices were: F0 = 127.77 Hz; F0 coefficient of variation = 2.51%; absolute jitter = 1.707 Hz; relative average perturbation = 0.0083; jitter factor = 1.34%; jitter ratio = 13.45%; QF = 0.447. The values for female voices were: F0 = 204.87 Hz; F0 coefficient of variation = 1.58%; absolute jitter = 3.30Hz; relative average perturbation = 0.0102; jitter factor = 1.60%; jitter ratio = 16.23%; QF = 0.443. Wave type for the entire sample was categorized as tilted pulse.Conclusion: Statistically significant differences were found for gender on parameters average F0 and absolute jitter. While using acoustic analysis software, users must be based on parameters inherent to the software program when analyzing the collected data. Braz J Otorhinolaryngol. 2012;78(4):29-34.

“…It has been found that shimmer is related to the roughness of one's voice quality [24,25] and SD F 0 is related to phonatory instability [26]. Therefore, it appears that the roughness of one's voice and phonatory instability are indicative of moods in both men and women.…”

“…Shimmer is computed as a percentage of A g and controlled by the roughness R voice dimension. Although typical values are approximately 2.3% for a normal voice [41], for simulation of very rough voices, a maximum of 100% shimmer on A g is allowed in the system. Shimmer is computed with the help of a centered random Gaussian noise generator N R with unity variance.…”

Cantor Digitalis is a performative singing synthesizer that is composed of two main parts: a chironomic control interface and a parametric voice synthesizer. The control interface is based on a pen/touch graphic tablet equipped with a template representing vocalic and melodic spaces. Hand and pen positions, pen pressure, and a graphical user interface are assigned to specific vocal controls. This interface allows for real-time accurate control over high-level singing synthesis parameters. The sound generation system is based on a parametric synthesizer that features a spectral voice source model, a vocal tract model consisting of parallel filters for vocalic formants and cascaded with anti-resonance for the spectral effect of hypo-pharynx cavities, and rules for parameter settings and source/filter dependencies between fundamental frequency, vocal effort, and formants. Because Cantor Digitalis is a parametric system, every aspect of voice quality can be controlled (e.g., vocal tract size, aperiodicities in the voice source, vowels, and so forth). It offers several presets for different voice types. Cantor Digitalis has been played on stage in several public concerts, and it has also been proven to be useful as a tool for voice pedagogy. The aim of this article is to provide a comprehensive technical overview of Cantor Digitalis.
