The Google system has achieved this year far better results than its competitors.
Correct answers in 93% of cases
Overall, the three assistants did well for comprehension, with 100% in terms of understanding for Google Assistant, 99.9% for Apple Siri and 99.8% for Amazon Alexa. Nevertheless, where Google Assistant does best, it is at the level of the results given. Thus, the Google system could provide a correct answer in 92.9% of cases, against 83.1% for Siri and 79.8% for Alexa.
In detail, Google is doing particularly well for navigation – with 98% of positive responses – and information – 96%. More surprisingly, Google Assistant does better than Alexa on queries related to e-commerce with 92% of completed queries against 71% on the Amazon wizard. Nevertheless, Google Assistant is overtaken by Siri in the interactions related to the orders of the smartphone, to send an SMS, to make a call or to access the calendar. Apple’s service was able to complete 93% of tasks compared to 86% for Google Assistant.
The results of this year’s study are consistent with last year’s results, where Google Assistant was already leading the way.
