Google NOW : A Better Voice Search Than Siri & Cortana

Magazine 23 Nov , 2014  


Google NOW , as you all know is an intelligent personal assistant developed by Google. It is available within the Google Search mobile application for the Android and iOS operating systems, as well as the Google Chrome web browser on personal computers. A new study by digital marketing consultancy company Stone Temple has shown that voice searches on Google Now blow Siri and Cortana out of the water.



Of those knowledge panels, Google Now search scored 88% accuracy for properly addressing questions, Siri came back right 53% of the time, and Cortana got 40%.



On to the new report, Stone Temple created 3086 different queries and compared them across all three platforms. These queries where not random, but rather they were specially formed queries that should evoke a full answer, or display a knowledge panel, from the search engine.

For example, “what is the highest mountain in the world?” Google Now not only tells you that Mount Everest is the tallest but it also lists the next two (K2 and Kanchenjunga) along with their heights. All Siri could do is display a web page with that information, while at least Cortana replies vocally with some information about Everest. This Implies Google Now understands context.




It uses a natural language user interface to answer questions, make recommendations, and perform actions by delegating requests to a set of web services. It recognizes repeated actions that a user performs on the device (common locations, repeated calendar appointments, search queries, etc.) to display more relevant information to the user in the form of “cards”.
The system leverages Google’s Knowledge Graph project, a system used to assemble more detailed search results by analysing their meaning and connections. Along with answering user-initiated queries, Google Now proactively delivers information to the user that it predicts they will want, based on their search habits.

Over almost all the 3000+ queries, Google Now returns twice as many enhanced results as Siri, and nearly three times as many enhanced results than Cortana. The actual numbers are shown in this graph from Stone Temple:
