P73 Continuous real-time rating of speech perception using connected mobile devices with emoTouch Web
The production and perception of speech are dynamic phenomena that evolve and change over time. Researching these dynamic phenomena therefore also requires dynamic research instruments that make the development processes continuously observable in real time. This requirement for a valid research approach for time-bound phenomena is basically similar to the situation in other fields, e.g. music, theater, dance, or sports.
To meet the need of different disciplines for an up-to-date, easy-to-use research tools for real-time research we developed 'emoTouch Web', a web-based research system for continuous real-time evaluation of videos, music or live events of any kind. The development at Osnabrück University (Germany) was funded by the Volkswagen Foundation. The system is available free of charge for scientific purposes.
The system turns any networked smartphone and tablet as well as any desktop computer into a flexibly configurable and easy-to-use tool for real time research. For example, the audience of a lecture can participate in a previously designed continuous evaluation study just by accessing a website with the smartphones they carry anyway ('Bring-Your-Own-Device'). This makes it possible in a simple way to comprehensively conduct studies at live events with possibly hundreds of participants at the same time. However, it is of course also possible to conduct studies with desktop computers in a laboratory setting or as an online real-time survey.
The poster presentation shows the possibilities of emoTouch Web by means of selected pilot studies and explains possible application scenarios in speech-related research, e.g. the continuous evaluation of the intelligibility during an evolving sound environment.
