Studies revealed a better voice assistant
A team of independent experts, having studied the work of Apple Siri, Google’s “Assistant” on the Home column and Android-smartphone, Microsoft Cortana and Amazon Alexa, named the best assistant. According to the results of the comparative analysis of Stone Temple Consulting, Google’s “Assistant” was recognized as the smartest assistant, just like a year ago.
Analysts asked each program for 5 thousand questions of various types, and the final score was made up of the number and accuracy of answers. Asking and comparing the assistants, the researchers took into account whether the program gave an oral explanation or requested a response from a database, such as the Knowledge Graph, whether it drew information from third-party sources, including Wikipedia.
Also mistakes were taken into account when assistants did not understand or misinterpreted the request. According to the results, Google’s assistant on the smartphone proved to be the best, Siri became an outsider: Apple’s assistant did not understand the request almost twice as often as the competitor.
Another group of researchers, ROAST, did not compare the “Assistant” with others. Experts asked the program Google 10 thousand questions from different areas and found out where it derives the answers. It turned out that the assistant’s answer did not always coincide with the results of the search engine. Even if the answer was to Google, the “Assistant” could ignore them and give out information from another source.
From the study, you can also find out that the “Assistant” on mobile devices is a little smarter than on Google Home. At the same time, the presence of an assistant in Android is just one of the features of the smartphone, while on smart speakers it performs the most important function.
Alexa continues to play a catching up role. The day before, Amazon was informed that their assistant would soon be able to remember the information at the request of the user, and would also begin to understand the context of the conversation. For comparison, the “Assistant” this function appeared in 2016. If you first ask him about a football club player and then ask him to give a number, the assistant will guess that the subsequent questions are probably related to the previous ones.
