Zusammenfassung
This paper investigates voice parameters as indicators of the user experience during their interaction with voice-based technology. Following the requirements of a non-intrusive measurement and an automatic analysis, a tool is developed, which automatically measures and analyses speech recordings of users during interactions with voice assistants. The tool distinguishes between user- and voice assistant speech and analyses mean amplitude and pitch of user's speech as parameters reflecting the user experience of users. A user study presents first steps of a validation of the first version and reveals limitations and requirements for further developments.
