Testimonials

Dr. Elina Tripoliti
"I just wanted to say thank you for my sound system. It has been extremely reliable, every week, with great sound on playback and great visual feedback for my patients."
— Dr. Elina Tripoliti, Speech-Language Pathologist Renowned scientist in motor speech disorders
Irena Bilić and Braco Boskovic
"We have been using the program for analyzing voice patterns in our laryngology clinic, and it has proven to be very efficient and reliable. The speed of data processing and the clear, well-organized workflow made it easy to integrate into everyday clinical work. From a clinician's perspective, the intuitive design and minimal need for manual intervention were particularly valuable, allowing us to focus more on patient care and interpretation of results rather than technical procedures. We also used the program for clinical research. The system enabled us to collect and analyze a large number of high-quality voice recordings within a relatively short time frame, which significantly improved both our research workflow and routine clinical efficiency."

Maja Rogić Vidaković
"We are highly satisfied with the implementation of the recording system developed by Vocalgebra in our research on vocal biomarkers in neurological and otorhinolaryngology subjects. The combination of the microphone, sound card, and software works seamlessly together, delivering professional-grade audio quality. It has significantly streamlined our workflow and exceeded our expectations. We would like to particularly emphasize our appreciation for the exceptional support provided by Dr. Jan Hlavnička, who has been consistently available to assist us with any challenges we encountered. Our interest in products by Vocalgebra was initiated by Dr. Hlavnička's published scientific work on vocal tremor. We were particularly impressed by the study: Hlavnička J, Tykalová T, Ulmanová O, Dušek P, Horáková D, Růžička E, Klempíř J, Rusz J. Characterizing vocal tremor in progressive neurological diseases via automated acoustic analyses. Clin Neurophysiol. 2020. This research has been highly influential for our own work in the field. We look forward to our future collaboration with Dr. Jan Hlavnička, as we firmly believe it is of paramount importance to develop simple solutions for voice signal collection and analysis that can be easily applied in everyday clinical practice."
