Introduction to Acoustic Analysis and Biofeedback in the Voice Studio


Acoustic analysis is commonly utilized in the clinical voice setting for evaluation, clinical decision-making, and real-time biofeedback. These same approaches have also been researched and written about their application to the singing voice. However, integrating that information into practical, easily implemented strategies for the singing voice studio remains challenging.
This workshop is intended for voice teachers who are interested in incorporating acoustic analysis and digital acoustic biofeedback into their voice studio, but are not sure how to start.* It will include suggested equipment setups, several free and open source options for acoustic analysis software, demonstrations and suggestions of scenarios in which these could be used to benefit voice instruction, and opportunities for participants to interact with and test these programs. Best practices for gathering acoustic data and relevant measures for the voice studio will be discussed, as well as options for hardware and software setup. Participants will practice recording and analyzing recorded files through various acoustic analysis software and scripts. The workshop will integrate this information into a voice lesson simulation that incorporates digital acoustic biofeedback. The majority of the time will be spent with hands-on interaction from participants.

Through participation in this workshop, attendees will:
1. Explore how to select an acoustic analysis setup for their studio and what components are necessary
2. Develop skills on recording and analyzing voice samples
3. Troubleshoot common errors and issues in collecting and analyzing acoustic information
4. Examine which acoustic variables to measure and how to interpret them
5. Identify various apps and software to be used for real-time or delayed biofeedback in a voice lesson
6. Evaluate when and how to implement apps and software for biofeedback in a voice lesson

* To get the most out of this workshop, participants should bring their laptops with Praat installed and updated. With a QR code, we will provide a Google Drive folder with access to recommendations for hardware, software, and apps, as well as files with software scripts to analyze acoustic information.
