Performance
Performance Theme Leader
Post Doctoral Research Fellow
Background
Inadequate sleep has widespread effects on core brain function and is known to induce changes in our performance, attention, and our ability to make decisions. In safety-critical environments, this can lead to human-error related accidents, incidents and injuries.
The way we speak can tell us a lot about our performance and ability to make decisions and can provide a non-invasive method to detect changes in our core function. Our performance theme investigates the use of speech signals to explore and determine if speech changes can be detected within various environments of stress, mental load and performance impairment.
Potential projects
These research project are available to PhD students to join as part of their thesis. Please contact the Theme Leader to discuss your options.
- speech as a signature biomarker of performance
- acoustic biometric analysis of speech for detecting decision making capacity under periods of stress
- acoustic biometric analysis of speech as a proxy for fitness for duty
