The link between vocal acoustics and non-clinical depression

Experiment conducted by Callum Dawson, under the guidance of Dr. Phil McAleer:

Thank you for your interest in taking part in this study. Please read the instructions carefully.

Purpose of the study

The purpose of this research is to investigate how someone’s voice can give an indication as to their level of depression. Specifically, this research aims to create a model of how different aspects of a voice (such as pitch) can explain how depressed someone is. Participation is voluntary and you are free to withdraw at any time without giving any reason.

Task instructions

You will be asked to complete two non –diagnostic questionnaires, one for life satisfaction and one for depression. Please note that there are no “right” or “wrong” answers. Please answer honestly but remembering that you can refuse to answer if you feel that you wish to do so. After completing both of theses, you will be given two options to record your voice. You can either join a zoom link that is set to record when you join and record yourself reading a passage of text (provided). Alternatively, you can use your phone to record your voice and upload it to an upload-only onedrive folder.

How long will participation take?

In total the experiment should take no more than 15 minutes. Approximately 5 minutes to complete the voice recording and a further 10 minutes to complete the two questionnaires. Please remember participation is voluntary and at any point you can withdraw from the experiment by closing the tab.

In addition, if after the experiment you no longer want your data to be used, you can contact Callum Dawson by email here: to delete your data.

What will happen to the results?

The results will be stored anonymously on a secure database within the School of Psychology and at no point will the data be identifiable as you. The data will be used by the research team for the purposes of a final year student project. In addition, the findings may be published within a peer-reviewed open access journal where again all data will be anonymised. Voice recordings will be stored with your participant data annonymized for use in future research if you consent to this.

Regarding the Questionnaires: Please note that this is a non-clinical, non-diagnostic experiment and as such we cannot tell you anything about your own scores in relation to your own mental wellbeing. If you are concerned about your mental wellbeing you should contact your local health and wellbeing team such as your GP or local health care provider.
