Google Now and Siri are both personal assistant software facilities. Google Now is the GoogleCorporation’s offering, while Siri is Apple’s Offering.
Google offers Google Now through a component of its mobile Google Search feature, as a part of its Android platform and as an installable feature for the iOS platform. On the other hand, Siri is Apple Corporation’s counterpart for Google Now. Apple provides it as part of the iOS platform.
Google Now first made an appearance as part of the mobile Google Search on the Android 4.1 platform, while Apple introduced Siri to the iOS platform after acquiring the Siri parent company that provided the service as an Apple application. The iPhone 4S was the first Apple device to support Siri. Afterwards, it came pre-installed in the iOS 5.
Google Now functions by scanning a mobile device’s user habits and preferences. That is, it notes of the pattern of your actions, the locations you visit, the emails you send and receive via Gmail and returns appropriate content as per the information you consume and provide in these services. For example, it can notify you how the traffic will look like on your evening drive or inform you on your upcoming appointment. Siri, on the other hand, can also consume the information traffic that passes through an iOS device to enable it to inform the device’s user of the upcoming events and events that are unfolding in the proximity. However, Siri goes a step further as it can automatically set posts for a user on social media. For example, it can post to Facebook and Twitter.
How they function
Google Now’s major form of interaction with the end user is by accepting voice commands. However, voice commands are the more outstanding function, because you can also interact with Google Now via typed text. To access the Google Now voice feature, power up a device’s voice search facility and say “OK, Google Now” into the device’s microphone. This will initiate the Google Now’s response mechanisms. Google Now answers straightforward questions like, “Who is the President of the United” and “What is the name of Japan’s capital city?” easily.
Going into the future, Google Now developers are improving the facility’s ability to hold a conversation with an end user in a near natural manner. To achieve this, Google Now’s capabilities are focusing on correct question answering and using no conventional interface to interact with an end user.
Google Now Cards are sectional interfaces that represent information pertaining to weather, traffic, and calendar details. As interfaces that contribute to the sum of the Google Now experience, the Google Now Cards populate their information using data from sites and other Google-related apps that a user regularly consumes.

Google Now Cards consist of traffic, birthdays, events, public transit, appointments, news, stocks, and weather cards. In additions other cards like movies, public alerts and nearby attractions improve a user’s interaction with amenities in her immediate locale.
To offer better interpretations of a user’s needs, Google Now uses the Google Knowledge Graph facility. This facility creates a connection between a user’s repeated keywords and tries to understand the user’s tastes, occupation, and places she visits regularly. Therefore, to be a worthwhile digital assistant, the user needs to feed Google Now with queries and data regularly. In addition, Google Now needs to be functional in a device for a while, before it displays the capabilities that developers intended for it. After a while, Google Now may be able to offer reminders about traffic, appointments in a manner that mirrors the user’s activities in real life.
A user may access Siri by pressing an iPhone’s home button (the only physical button the iPhone’s face, actually). This action initiates an interaction session between the user and Siri, where the user gets access to information from apps like Clocks, Wolfram Alpha, Maps, Calendar, Contacts, Reminders, Notes, Music, and Stocks.Siri differs from Google Now’s casual use because it emphasizes on the use of language that mimics a conversation between people, while Google Now seems to be more keyword-like instructions. For example, a user may tell Siri, “I want to pick the kids from school at 4 pm”. Siri then creates an appointment and automatically launches the corresponding app to let the user confirm the act. As is the case with Google Now, a user may ask Siri about specific information and it will return the appropriate pointers. For example, a user can ask Siri what the price current price of Nestle stock is at that moment, and it will reply with the correct quote.
While still in its early stages of development and lacking across a majority of Android-powered devices, Google Now’s conversation capabilities are the next immediate frontier in Google Now’s development. This capability hinges on developers rapidly improving the capability of Google’s Knowledge Graph. This is Google Now’s weakness when compared to Apple’s Siri. A Google Now user may rate her experience as one of providing keywords, in contrast to holding a conversation. Nevertheless, Google Now’s use of the Knowledge Graph provides with the capability to formulate responses intelligently from a session of querying that contains incomplete sentences. For example, a user may ask Google Now, “What is the name of the current male Wimbledon tennis title holder?”, and then follow it with, “how old is he?”The Knowledge Graph has the capability to know that the second question was referring to the male Wimbledon titleholder.
A Siri user can speak several continuous sentences into an iPhone, and it will create the session into text after the user finishes. This feature can provide input for SMS, email and even posts for social media services.
The intelligent personal assistants provide a convergence of technology that would one day make mobile devices run off truly artificially intelligent platforms. The use of Siri and Google Now illustrates how mobile devices are developing into devices that have fewer physical interfaces. Consequently, advances in technology paint a picture of a future with devices that interact naturally with their users, and remove the need for people to learn complex interface routines in order to benefit from the device’s full functionality.
