A trustworthy speech interface : A study on vocal design of an Intelligent Personal Assistant (English)
Abstract [sv]

Modern teknik som intelligenta personliga assistenter (IPA) som finns i smartphones kan förenkla människors vardagliga liv. De kan hjälpa personer med funktionshinder och människor som lever stressfulla liv. Genom tal, kan IPA:er enkelt hjälpa personer som ofta har händerna fulla att hitta vägbeskrivningar, information eller skicka meddelanden över hela världen. För att locka människor till att förlita sig på IPA:er i det dagliga livet räcker det inte att den är intelligent och tilltalande, den måste också vara tillförlitlig.

Det finns många faktorer som är involverade i att bygga ett trovärdigt system. Denna uppsats fokuserar på att ta reda på vilka egenskaper som gör en IPA:s röst trovärdig och vilken typ av röster designers bör göra tillgängliga för sina användare. Kvalitativa och kvantitativa forskningsmetoder har använts i studien. Sammanlagt 11 semi-strukturerade intervjuer genomfördes och varje innehöll ett kort användartest. 100 personer deltog i en enkätundersökning med ljudklipp och specifika frågor om egenskaper hos pålitliga IPA röster. 70 av 100 tillfrågade var överens om att röster som medför känslor, speciellt en känsla av trygghet och lugn, gör en IPA-röst trovärdig. Att låta tydlig, behaglig, människoliknande och erfaren, samt att ha en dialekt som användaren kan relatera till anses också vara viktiga röstegenskaper. Kön anses vara den minst viktiga.

Abstract [en]

Modern technologies such as intelligent personal assistants (IPA) found in smartphones can simplify the daily lives of people. They are not only useful for people with disabilities but also for those who live stressful lives. Through speech, IPAs can easily help a busy full-handed person find directions, information or send messages across the world. To entice people into relying on IPAs in their daily life, it not only has to be intelligent or appealing enough but also trustworthy.

There are many principles involved in building a trustworthy system. This paper focuses on finding out what characteristics make an IPA-voice trustworthy and what kind of voices designers should make available for their users. Qualitative and quantitative research methods were used in the study. A total of 11 semi-structured interviews were carried out each in conjunction with a brief user test. 100 people participated in a survey with audio clips and specific questions regarding characteristics of trustworthy IPA-voices. 70 of 100 respondents agreed that voices that bring about emotions, particularly the feeling of security and tranquility, make an IPA-voice trustworthy. To sound clear, pleasant, human-like and experienced, and have a dialect that the user can relate to are also considered important voice qualities. Gender is considered the least important.
