This paper studies the usability methodologies for spoken dialogue web interfaces along with the appropriate designer-needs analysis. The work unfolds a theoretical perspective to the methods that are extensively used and provides a framework description for creating and testing usable content and applications for conversational interfaces. The main concerns include the design issues for usability testing and evaluation during the development lifecycle, the basic customer experience metrics and the problems that arise after the deployment of real-life systems. Through the discussion of the evaluation and testing methods, this paper argues on the importance and the potential of wizard-based functional assessment and usability testing for deployed systems, presenting an appropriate environment as part of an integrated development framework.

This chapter presents the state-of-the-art in usability issues and methodologies for spoken dialogue web interfaces along with the appropriate designer-needs analysis. It is planned to unfold a theoretical perspective to the usability methodology and provide a framework description for creating and testing usable content and applications for conversational interfaces. Main concerns include the problem identification of design issues for usability design and evaluation, the use of customer experience for the design of voice-web interfaces and dialogue, and the problems that arise from real-life deployment. Moreover, it discusses the hands-on approaches for applying usability methodologies in a spoken dialogue web application environment, including methodological and design issues, resource management, implementation using existing technologies for usability evaluation in several stages of the design and deployment.

This chapter presents the state-of-the-art in usability issues and methodologies for VoiceWeb interfaces. It undertakes a theoretical perspective to the usability methodology and provides a framework description for creating and testing usable content and applications for conversational interfaces. The methodologies and their uses are discussed as well as certain technical issues that are of specific importance for each type of system. Moreover, it discusses the hands-on approaches for applying usability methodologies in a spoken dialogue web application environment, including methodological and design issues, resource management, implementation using existing technologies for usability evaluation in several stages of the design and deployment. Finally, the challenging usability issues and parameters of the emerging advanced speech-enabled web interfaces are presented.

Usability testing is typically taught with a desktop or mobile device in mind. As new platforms become more commonplace, it is important to master usability testing as applications scale cross-platform (including television, virtual reality, voice user interfaces, and screen readers). For all devices, there are key considerations across study recruitment, selection of the right prototype fidelity, lab research (including lab environment, observing, and recording the participant), and moderated remote research that should be kept in mind. This paper aggregates best practices for all six devices across these various topics.

The paper presents research results emerging from the analysis of Intelligent Personal Assistants (IPA) log data. Based on the assump­tion that media and data, as part of practice, are produced and used cooperatively, the paper discusses how IPA log data can be used to analyze (1) how the IPA systems operate through their connection to platforms and infrastructures, (2) how the dialog systems are de­signed today and (3) how users integrate them into their everyday social interaction. It also asks in which everyday practical contexts the IPA are placed on the system side and on the user side, and how privacy issues in particular are negotiated. It is argued that, in order to be able to investigate these questions, the technical-institutional and the cultural-theoretical perspective on media, which is common in German media linguistics, has to be complemented by a more fun­damental, i.e. social-theoretical and interactionist perspective.

Abstract Flexible piezoelectric acoustic sensors (f-PAS) have attracted significant attention as a promising component for voice user interfaces (VUI) in the era of artificial intelligence of things (AIoT). The signal distortion issue of highly sensitive biomimetic f-PAS is one of the most challenging obstacle for real-life applications, due to the fundamental difference compared with the conventional microphones. Here, a noise-robust flexible piezoelectric acoustic sensor (NPAS) is demonstrated by designing the multi-resonant bands outside the noise dominant frequency range. Broad voice coverage up to 8 kHz is achieved by adopting an advanced piezoelectric membrane with the optimized polymer ratio. Deep learning-based speech processing of multi-channel NPAS is demonstrated to show the outstanding improvement in speaker recognition and speech enhancement compared to a commercial microphone. Finally, the NPAS independently identified the multi-user voices in a crowd condition, showing simultaneous speaker separation.
