Smart devices are widely available and capable of quickly recording and uploading speech segments for health-related analysis. The switch from laboratory recordings with professional-grade microphone setups to remote, smart device-based recordings offers immense potential for the scalability of voice assessment.

The tested plug-and-play microphones should not be used interchangeably with professional-grade microphones for speech analysis. Plug-and-play microphones may assist in equipment standardization within speech studies, including remote or self-recording, possibly with a small loss in accuracy and statistical power as observed in the current study. It was also found that bring your own device (BYOD) needs careful consideration when designing speech studies.

This study was conducted in collaboration with The University of Melbourne, Monash University, University at Buffalo and Bionics Institute.
