Comparison of Virtual Assistants

Computers get smarter every year.
They can solve complex math problems, analyze data, steer planes, build cars, and even turn off your stove remotely. They may soon drive you to work.
Virtual assistants can also give you instant answers to virtually any question. Virtual assistants are used by approximately 77 percent of Americans who have smartphones.
You might be interested in how Siri, Cortana and Google Now compare to Alexa. To find out how each device compares, we did some research and surveyed 100 users. Continue reading to find out more.

Who is the best with verbal commands?

We asked respondents to rate their satisfaction with their mobile assistants. The results were very positive. Siri had a 66% satisfaction rate, while Google Now’s voice recognition was a 59 percent satisfaction rate. Cortana had a 46 percent satisfaction rating.
Siri scored the highest across all environments, with almost 63 percent of respondents happy with Siri’s performance in noisy environments compared to nearly 68 percent in quiet environments. Google Now had a greater discrepancy in performance with only 55 percent of respondents satisfied in noisy environments and 64 percent in quiet environments. In both cases, Cortana’s satisfaction rate was less than 50%.
It turns out that background noise can make it harder for your commands to be understood. One tech writer stated that Siri and other virtual assistants still have difficulty understanding queries in less than ideal acoustic environments because microphone technology has been somewhat stagnant over the years.
Next, we compared Alexa and Google Home. Overall, Alexa won with a 51% satisfaction rate, while Google Home had just under 47%. Alexa had a lower satisfaction rate in noisy environments than Google Home, while it was just over 5 percent for Alexa. In quieter areas, it was just over 3 percent. Tech reviewers tend agree with this conclusion, ranking Amazon’s product higher in home assistants than Google.

Virtual Assistants in Noisy Spaces vs Silent Spaces

When asked to perform specific tasks in quiet areas, Siri, Alexa, Google Now and Google Now accounted for all the first place results. Alexa was the best at playing songs on command, while Google Now was the best at providing directions to nearby stores.

We found different results in noisy airport lounges and rooms full of laughing houseguests. Siri came in first place in noisy environments and tied Google Now for second place across all categories. Siri was last for playing a particular song in quiet and noisy rooms. This task was performed by Alexa the best of all virtual assistants.

Beyond background noise

Siri’s performance in background noise is the best. It completes tasks when asked for it in 65 percent of cases. Google Home understood commands and questions only 45 percent of the time.
As it turns out, phone cases also make a difference in the ability of virtual assistants to understand us. Siri received requests in silence about 71% of the times when participants’ phones were not in a cover, and 68% of the cases when they were. Google Now received requests 66 percent of time without a case, and 58 percent when it had a case.
Also, Alexa and Cortana, Google Now and Siri were more likely to follow directions if they were given by a female voice. Google Home made it r
