Voice assistants type of voice in autonomous vehicles and its impact on trust and situation awareness : A study on how feminine and masculine voices in voice assistants affect drivers' situational awareness and perceived trust in autonomous vehicles (English)
Abstract [sv]

Utvecklingen inom fordonsindustrin går mot autonoma fordon, och som effekt av det behöver både säkerhet och samhällets acceptans öka. För att öka säkerheten i autonoma fordon behöver föraren vara situationsmedveten, vilket kan uppnås genom en röstassistent i fordonet. Om säkerheten skulle öka skulle sannolikt även människors tillit och därav samhällets acceptans öka. Studier pekar på att olika egenskaper så som rösttyp hos röstassistenter kan ha en effekt på förares situationsmedvetenhet och tillit. Denna studie ämnar således att undersöka huruvida en feminin eller maskulin röst hos röstassistenter påverkar förares situationsmedvetenhet och upplevda tillit till autonoma fordon. För att ta reda på detta genomfördes en experimentell studie där deltagare befann sig i en bilsimulator av ett autonomt fordon som simulerade körscenarier. Deltagarna var uppdelade i två grupper där varje grupp fick uppleva en typ av röstassistent, antingen med feminin eller maskulin röst. Deltagarna fick uppleva körscenarier där varningssituationer i olika allvarlighetsgrader uppstod, där de fick fatta beslut kring hur de hade hanterat varningssituationen. I samband med körscenarierna utfördes tre olika datainsamlingar bestående av intervju och enkäter. Resultatet av studien påvisar ingen signifikant eller utmärkande skillnad vad gäller upplevd tillit mellan grupper. Resultatet indikerar inte heller någon utmärkande skillnad mellan gruppernas situationsmedvetenhet. Det finns marginell skillnad mellan grupperna, där gruppen som upplevde feminin röst hade både högre upplevd tillit och situationsmedvetenhet. Slutresultatet i denna studie visar att området behöver utforskas vidare för att upptäcka och förstå eventuella effekter av rösttyper hos röstassistenter. 

Abstract [en]

The development in the automotive industry is moving towards autonomous vehicles, and as a consequence the need to increase both safety and societal acceptance is necessary. To increase safety in autonomous vehicles, the driver needs to be situationally aware, which can be achieved through a voice assistant in the vehicle. If safety were to increase, people's trust and therefore society's acceptance would most likely also increase. Studies indicate that different characteristics of voice assistants, such as the type of voice, can have an effect on drivers' situational awareness and trust. Thus, this study aims to investigate whether a feminine or masculine voice in voice assistants affects drivers' situational awareness and perceived trust in autonomous vehicles. An experimental study was conducted in order to investigate this, where participants were situated in a simulator of an autonomous vehicle that simulated driving scenarios. The participants were divided into two groups where each group experienced one of two types of voice assistants, either with a feminine or a masculine voice. The participants had to experience driving scenarios where warning situations of varying degrees of severity arose, where they had to make decisions about how they would have handled the situation. In connection with the driving scenarios, three types of data collections consisting of interviews and questionnaires were carried out. The results of the study show no significant or distinctive difference in terms of perceived trust between groups. The results also don’t indicate any distinctive difference between the groups' situational awareness. There is marginal difference between the groups, with the group experiencing feminine voice having both higher perceived trust and situational awareness. The final result of this study shows that this research area needs to be explored further to discover and understand the possible effects of voice types in voice assistants.
