    Age-Related Differences in Preferences for Using Voice Assistants
    (Mensch und Computer 2021 - Tagungsband, 2021) Gollasch, David; Weber, Gerhard
    In the past fewyears, voice assistants have become broadly available in different forms of presentation and devices – not only as a personal assistant within smartphones but as smart speakers, within TV sets or as part of an in-car infotainment system. Furthermore, we live in an ageing society and considering elderly people as users of voice assistants gains more relevance driven by both trends. The goal of this study is to identify the specific age-related preferences of older people when using a conversational user interface in form of a voice assistant. We conducted a survey based on 26 elderlyrelated communication strategies among participants of different age. The participants had to evaluate the strategies according to their own preferences for using voice assistants. As a result, we identified 11 preferences specific to older users. Surprisingly, most of the communication strategies, when applied to voice assistants, seem to be relevant for users of all ages, and a few of the communication strategies do not apply when used in voice assistants. The preferences specific to older people help to develop new guidelines for voice user interfaces or conversational user interfaces in general. They do not automatically lead to those guidelines but provide a foundation to derive requirements, develop guidelines and evaluate those guidelines by means of user-based usability tests.

    Designing VUIs for Social Assistance Robots for People with Dementia
    (Mensch und Computer 2021 - Tagungsband, 2021) Striegl, Julian; Gollasch, David; Loitsch, Claudia; Weber, Gerhard
    Elderly people and especially people with dementia often experience social isolation and need assistance while performing activities of daily living. We investigate a novel approach to cope with this problem by integrating voice assistants and social assistance robots. Due to the special communication needs of people with mild cognitive impairment, the design of interfaces of such systems is to be based on the particular requirements of the target user group. This paper investigates, how a voice user interface should be designed for elderly users with mild cognitive impairment – such as an early stage of dementia – to provide personalised support throughout activities of daily living. A context and user analysis delivered a set of 11 guidelines for voice user interfaces for people with dementia. For a pilot study we selected those strategies often applied by caregivers in their communication with people with dementia and evaluated the voice user interface among elderly participants and healthcare workers who reported a high feasibility, usefulness and acceptance of the designed system.

    Faire KI-basierte Sprachassistenten
    (HMD Praxis der Wirtschaftsinformatik: Vol. 61, No. 2, 2024) Weith, Helena
    Obwohl Sprachassistenten Vorteile wie personalisierte Empfehlungen und Kommunikation, lediglich basierend auf Sprache, für Nutzer und Unternehmen mit sich bringen, besteht das Risiko, dass diese unfair agieren. Die technische und soziale Fairnessperspektive wurde bislang isoliert voneinander betrachtet. Es ist relevant eine gemeinschaftliche sozio-technische Fairnessperspektive vorzunehmen, mangelt allerdings an konkreten Maßnahmen, um diese sozio-technische Fairnes für Sprachassistenten zu erreichen. Daher liefert dieser Artikel basierend auf zwölf Experteninterviews ein Framework, welches fünf Handlungsfelder sowie dazugehörige konkrete Maßnahmen aufzeigt, die Unternehmen adressieren müssen, um die sozio-technische Fairness von Sprachassistenten zu erzielen. Dabei bauen die Ergebnisse auf dem Konzept der sozio-technischen Fairness auf, erweitern diese jedoch unter der Berücksichtigung der spezifischen Eigenschaften und Herausforderungen von Sprachassistenten um konkrete Maßnahmen. Unternehmen erhalten eine übergreifende Übersicht von Maßnahmen, um die sozio-technische Fairness von Sprachassistenten herzustellen. Although voice assistants bring benefits to users and businesses, there is a risk of them being unfair. The technical and social fairness perspectives have so far mainly been considered separate, but it is relevant to consider the socio-technical fairness perspective and identify how it can be achieved for AI-based voice assistants. Based on 12 expert interviews, this article, therefore, provides a framework including five fields of action and corresponding measures companies should address in order to achieve socio-technical fairness of voice assistants. The results build on the concept of socio-technical fairness, considering the specific characteristics and challenges of voice assistants. This article provides companies with a comprehensive overview of measures to ensure the socio-technical fairness of voice assistants.

    Hilfsbereit, verständnisvoll, bescheiden: Problematik und Folgen von weiblichen Voice Assistants
    (HMD Praxis der Wirtschaftsinformatik: Vol. 59, No. 2, 2022) Hefti, Sarah
    Der Artikel legt die soziale und ethische Problematik weiblich konzipierter Voice Assistants dar. Weibliche Voice Assistants, die folgsam bis unterwürfig die ihnen aufgetragenen Arbeiten erledigen und selbst bei Beleidigungen höflich bleiben, können geschlechterstereotype Erwartungen an Frauen in der Gesellschaft hervorrufen und festigen. Angesichts der weltweit starken Zunahme von Voice Assistants ist dies ein Aspekt, der unbedingt thematisiert werden sollte. Die menschliche respektive weibliche Inszenierung der Technologie fusst auf grösstenteils bewussten Entscheidungen der beteiligten Design- und Entwicklungsteams. Sie programmieren geschlechterstereotype Reaktionen, setzen auf weibliche Stimmen und Namen. Die einfach gestrickten, hilfsbereiten weiblichen Voice Assistants können als hochmoderne Technologie Geschlechterstereotype nicht nur abbilden, sondern sie auch direkt zurück an ihre Nutzer:innen spielen. Damit verfügen sie über das Potenzial, längst ausgediente Rollenbilder in der Realität zu nähren. Der Artikel erörtert diese Problematik und analysiert hierfür aktuelle Literatur- und Medienbeiträge. Abschliessend werden mögliche Handlungsfelder für Technologiekonzerne, Forschung, Gesetzgebung und Zivilgesellschaft abgeleitet. Der Weg führt über eine stärkere Sensibilisierung aller an der Entwicklung Beteiligten und der Nutzer:innen. Nur so können Alternativen zu den gängigen Voice Assistants entstehen. The article discusses the social and ethical problems of female voice assistants. Female voice assistants obediently—if not to say submissively—perform their assigned tasks. They remain polite even when insulted. Consequently, they can create and reinforce gender-stereotypical expectations of women in society. Given the significant increase in voice assistants worldwide, this is an aspect that must be addressed. The human respectively female representation of the technology is based on mostly conscious decisions of the development and design teams involved. They program gender-stereotypical reactions, choose female voices and names. The simple, helpful female voice assistants not only reproduce gender stereotypes but also play them back directly to their users as state-of-the-art technology. As a result, female voice assistants can cement outdated gender stereotypes in reality. The article discusses this topic and analyzes current literature and media coverage. Finally, possible fields of action for technology companies, research, legislation, and civil society are derived. The way forward is to raise the awareness of all those involved in developing and using the technology. Only then will it be possible to establish alternatives to the current voice assistants.

    Using SQL/MED to Query Heterogeneous Data Sources with Alexa Voice Commands
    (BTW 2023, 2023) Schildgen, Johannes; Heinz, Florian; Olijnyk, Andreas; Lindenau, Arvid
    Typical Alexa skills and other add-ons for voice assistants need to be custom developed for their one specific use case. This paper presents an approach to map arbitrary data sources (databases, APIs, services) to the relational model by using SQL/MED and to transform voice-based queries into SQL. The key challenges for such a universal skill are to correctly map the natural-language question into a SQL query on the correct source table in the federated database and to convert the result set back to a compact and well-understandable answer.

    What 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 assistants
    (Mensch und Computer 2020 - Workshopband, 2020) Obremski, David; Wienrich, Carolin; Carolus, Astrid
    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.
