A digital assistant is primarily controlled by a user’s voice, and so its ability to know when it’s being spoken to, and to understand what’s being said, is important. Each one has a wake word or phrase that it listens for, such as “Hey Cortana,” “Ok, Google,” and “Alexa,” which tells the digital assistant to listen and respond to what’s said next — but if you have a niche accent or don’t like to shout, are some assistants better at understanding you than others?
While each of the major voice assistants offers good voice recognition, Google Assistant and Siriare better at picking up what you say, especially when there is environmental noise, or the assistant itself is relaying some information to the user. Microsoft claims Cortana has a good understanding of context, but it struggles much more than the other two in actually hearing what you’re saying. Silent environments are best when using it, as background noise can really interfere with it picking up what you’re asking of it.
In terms of response time to queries, Google Assistant comes out on top again, consistently providing fast replies to requests. Cortana and Siri were both hot on its heels, however. When the request is picked up clearly by the alternative digital assistants, Cortana can often edge out Siri, but it very much depends on the requests you make of them.
