EUPL as a tool for ScienceDirect

Published on: 26/03/2018

It is often said that the EUPL was designed as a legal interoperability tool aimed at facilitating the sharing and reuse of software resources by public sector administration. While this is true, there is an equal interest from industry and research for adopting the open source development model. In particular it facilitates the distribution and reuse of scientific works.

A recent example is FonaDyn, A system for real-time analysis of the voice range that is distributed under the EUPL v1.2. From soft to loud and low to high, the mechanisms of human voice have many degrees of freedom, making it difficult to assess phonation from the acoustic signal alone. FonaDyn is a research tool that combines acoustics with electroglottography (EGG).

The system was designed to identify automatically different vibratory states of the vocal folds, and to map these across the voice range, rather than to analyze only isolated sustained vowels, which is the current convention in clinical analysis. Provided that the vocal fold vibration is reasonably periodic, FonaDyn thus affords a new overview of phonatory behavior that can guide researchers in the quest for accounting for the large variability in the voice.

The potential use of such system is scientific, clinical where it can be applied to map the phonatory status of patients e.g. pre- and post intervention, pedagogical to guide a student to pronounce or a singer to vocalize in a more optimal way, not to speak about improving voice recognition and other applications.

Studies to these ends are under way.
