VoiLA: An Online Intelligent Speech Analysis and Collection Platform

In this study, we propose the novel Voice AnaLysis Application “VoiLA”, a free web-based speech classification tool designed to educate users about state-of-the-art speech analysis paradigms. Further, the platform encourages users to take an active role in improving the service by providing labelled speech data via an associated web interface. VoiLA allows users to record and upload voice samples directly from their browser. The speech data is then analysed in a state-of-the-art classification pipeline, using a set of pre-trained models which target a range of speaker states and traits such as gender, valence, arousal, dominance, and 24 different discrete emotions. The analysis results are then visualised in the browser, giving users a unique insight into how their voice sounds. We assess the effectiveness of VoiLA via a series of user evaluations which indicate that it is fun and easy to use and routinely provides accurate and informative voice analysis.
