Audio Playground

Audio Playground is a software created by The BMS Lab. The software is currently a testing environment due to it currently being a development version. Researchers at the University of Twente can use it to (1) automatically transcribe audio to text, (2) analyze audio, and (3) analyze text. Through the (2) audio analysis and (3) text analysis, the researcher can obtain an overview of the total words spoken per turn and speaker, turn allocation per speaker, and the percentage of turns per speaker. Additionally, the audio analysis enables the researcher to code specific audio fragments while the text analysis enables the researcher to classify the data further through sentiment analysis and emotion analysis. ​ 

Audio Playground for Research and Education #

At the BMS Lab, the Audio Playground’s development version has not been used yet to conduct research. However, the Audio Playground can be used in a class were students learn how to code audio files and basic measurements such as word amount and translations.

Best Practices #

To reduce potential issues and challenges, keep the following points in mind before using Audio Playground for your research:

Planning Your Research Design #

  1. 1. Think about what you would like to measure? When? What will it deliver afterwards? And how does Audio Playground fit within your research. This helps you realize what you need to build, when and how much time it will likely take.
  2. 2. Take practical aspects into account: is there an easier way to do it? Uncertain? Ask the BMS Lab.
  3. 3. Consider the limitations of the software to your study. Keep in mind that Audio Playground is a development version which means that any uploaded or produced data in the testing environment can be deleted or lost at any time as a result.

Developing Your Research #

  1. 1. Ensure that you have approximately 2 – 3 weeks to build your research. You might need to adapt your methodology based on Audio Playground’s functionalities (see “Further Support” section) or you might need time to get an answer from the BMS Lab.
  2. 2. Your introduction screen should adequately inform your participants and meet the BMS faculty’s ethical standard on informed consent.
  3. 3. Any time you make new additions, make sure to regularly test your research from the participant’s perspective.
  4. 4. Duplicate your research to have a clean back-up version.
  5. 5. Test your final version as a participant.
  6. 6. Found a bug or issue? Go to the troubleshooting section and fill in the form.
