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.

The Guardian recently revealed that, like Google Assistant and Alexa, Siri was collecting audio clips of conversations to make them listen and analyze by humans.

In addition to weakening the speech on the protection of privacy of Apple, it turns out that these subcontractors could also fall on recordings of unwanted requests.

Apple wants to conduct a “comprehensive review ” of its quality improvement system from Siri. The manufacturer also indicates that a setting will be set up to allow users to no longer participate in the listener. This option will appear in a future update of Apple’s operating systems.
