Design outcomes

Primary

MeasureTime frame
The aim of this study is to create a dataset that enables the investigation of vocal differences across various phases of the menstrual cycle. To this end, voice recordings will be made in three different phases. These include a sustained vowel, read sentences, an image description task, and a free speech task. Various voice parameters will then be extracted from the recordings and analysed.
