I’m unsure about using it for bankingService complexity
The perceived complication or difficulty of using voice commerce for specific services, including those requiring detailed information or sensitive transactions
Service attributes
The characteristics of the service being provided that influence consumer perceptions and behaviors in voice commerce
For a restaurant reservation and you know what you’re going to order [I might just say] make my usual reservation and order my usual plate
If it’s a plane ticket, a lot of things can go wrong
I’d ask Alexa to find the cheapest flight on KayakService consumption phase
The specific stage in the service consumption process where voice commerce is utilized (e.g. pre-purchase, service consumption, post-purchase)
Voice should be used only where it’s apt in the purchase process
It’s fine until tasks like account creation or adding payment methods
I’d only use it for platforms or brands I deeply trust and valueBrand familiarity
The extent to which consumers recognize and have prior experience with a brand, which influences their willingness to use voice commerce for purchasing that brand’s products
Service provider attributes
The characteristics of the service provider that shape consumer perceptions and behavior in voice commerce
If it’s a luxury brand known for quality, I’d trust their service without prior experience
I generally lean toward brands I’ve used before. Why risk something unknown?
It should be simpler and faster than other channels, delivering the same resultsMultichannel integration
The degree to which voice commerce is seamlessly integrated with other service channels (e.g. app, website), providing a consistent and cohesive customer experience
The process should mimic how you’d do it yourself on the app or website, but with a voice assistant guiding each step
A hybrid approach works best. I’d use it as a supplementary tool
The convenience of having things delivered home with minimal effort is appealingPerceived relative advantage
The extent to which voice commerce is viewed as offering benefits over existing methods, such as convenience, speed or reduced effort
Consumer attributes
The characteristics or perceptions of consumers that affect their behaviors toward voice commerce
If it simplifies life or aids in urgent situations, that’s valuable
Speaking is more comfortable than typing, so I’d rather ask directly
There’s a fear of conversations being leaked, leading to potential blackmailPerceived privacy risk
The concerns about the potential for misuse or unauthorized access to personal data when using voice commerce
There’s always insecurity because you can’t see what you’re buying, just discussing it
Trust issues arise. What if the voice assistant doesn’t complete the transaction correctly?
After successfully navigating it a few times, my trust would be stronger. It’s like cultivating trust with an algorithmUser familiarity
The level of comfort or ease a consumer has in using voice commerce based on prior experience and repeated interactions
Once familiarized, it certainly streamlines the process, saving time and proving its efficiency
Perhaps, introduce it for specific tasks. Once it proves reliable, I’d use it more
If a friend recommends it, I might try itSocial influence and normative pressures
The influence of social norms and the behaviors of others on a consumer’s willingness to adopt and use voice commerce
I use it mainly because others do. If many adopt it, there’s probably a good reason
I noticed many people using it and found it intriguing. That prompted me to try
