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.enUser ExperienceVoice AssistantsSpeechWhat the user’s voice tells us about UX - Analysing parameters of the voice as indicators of the User Experience of the usage of intelligent voice assistantsText/Workshop Paper10.18420/muc2020-ws105-377
