Purpose:
Voice acoustic analysis informs both scientific research and clinical voice rehabilitation. Adopting voice dosimetry would expand the use of acoustic measurement methods to collect data in the daily lives of individuals with voice disorders. In this editorial article, instructions for an open access, easy-to-use, and automated voice acoustic analysis software are provided. An implementation of this do-it-yourself (DIY) Voice Acoustic Analysis software is also provided.
Method:
The DIY Voice Acoustic Analysis software was developed using Python. Key acoustic voice parameters are included: sound pressure level (SPL), fundamental frequency, cepstral peak prominence (CPP), and vocal doses. Further, this software was implemented to analyze voice recordings from a university professor who wore a previously developed DIY Voice Dosimeter device for the duration of a 70-minute lecture.
Results:
The DIY Voice Acoustic Analysis software is available at https://github.com/SpAA-LAB/Dosimetry-App, and instruction videos are further available at that link. The present article demonstrates the software using the voice recordings from the professor.
Conclusion:
The DIY Voice Acoustic Analysis software is a tool for accessible voice measurement and is especially well-suited to be implemented in conjunction with the DIY Voice Dosimeter device.
