It is clear that with the arrival of smart speakers, the virtual assistants offered by each company will have to be significantly improved. In your case Siri was the first, but that has by no means assured him of being the bestIn fact, he still has a lot to learn.
The evidence is evident, the latest analysis makes it quite clear that Siri still leaves much to be desired. This is perhaps what Apple should prioritize if it intends to expand its smart speaker reasonably.
Charts and Loup Venture have wanted to test the four main competitors in this virtual assistants, we have: Siri, Cortana, Alexa and Google Assistant. It is clear that here Google plays with an obvious advantage, the huge amount of personal data that it handles in order to offer a better service if possible. I do not want to overwhelm you with data, they have simply been asking a series of questions to the virtual assistants, delimiting the extent to which they are able to understand the actions that are requested and of course their response capacity. At first glance, Google's virtual assistant plays in a higher league to that of its most direct rivals.
There is only one point where Siri beats the Google product, in the commands, that is, those interactions with the Prisco that are aimed at controlling its operation. I have tried a Google Home, and I have to say that the results were totally poor at these levels, in fact, I have to say that Amazon's Alexa is offering me higher returns. However, in general terms Google continues to give better answers and solve our doubts much better. Now with Apple Shorcuts this situation can be reversed, but the user would have to take command of the game. Apple has a pending issue with Siri and a lot of work ahead if it wants to really popularize the use of these devices.
