What is Siri?

Siri is a built-in voice controlled personal assistant created for Apple devices. Siri has been designed to offer a seamless experience to interact with devices like the iPhone, iPad, Apple watch by speaking to Siri and finding out what you want to know. You can ask Siri questions, tell her to show something, or execute a task using a command for your benefit, hands-free.

It is also capable of setting reminders, scheduling event, counting down a timer, and even booking reservations at a restaurant. Siri extends a lot of functionality by using your voice. You can now even skip typing on the keyboard and use your voice for a dictation instead.

Siri will have access to the built-in application on your Apple device. It will include Contacts, Mail, Safari, Maps, and messages. Siri can access those apps and search their database when needed. You can carry out tasks by saying “Hey Siri” or by double tapping on the Home button. Time will be saved with Siri as you will not need to open multiple apps, find contacts or write messages.

Your device will usually have Siri turned on, but if it is not activated, you can open up the settings of the device and activate it. You can also activate Siri by saying “Hey Siri,” rather than having to press down on the Home button. By using Siri’s settings, you can also change the voice from female to male. You are also free to change the accent or the language.

Siri has been around for a few years now. This personal assistant was launched with the iPhone 4S and was said to be the best thing on the iPhone. Siri has been developing with age, and her abilities and intelligence have grown as well.

What is Google Assistant?

Google is taking on Alexa, Amazon, Apple Siri, and Microsoft Cortana with its own personal assistant known as Google Assistant. Google Assistant was unveiled in May 2016 at the Google I/O event.

Google Assistant is designed to be personal and an expansion of the OK Google voice control. Users who have been using Android devices may already know that Google Now smartly pulls out relevant information. It knows information like where you work, your locations and meeting, travel plans, your interests.

Hey, Google and OK Google, on the other hand, cover voice commands, lets you send messages, voice activated device controls, and check appointments, just the way Apple Siri works on iPad and iPhone. Google assistant fuses all these features together to produce a bot centric Artificial Intelligence experience which covers both areas with conversational interactions.

Although many devices are capable of supporting Google Assistant, the full experience is integrated into the Google Pixel devices. It also comes in a very different iteration in Google Allo. Google will make Google Assistant available in Android devices in the near future.

What is Alexa?

Alexa, the Amazon personal assistant, has been around for some time. It is also evolving to become smarter. It allows its users to dictate commands to control home products in their home, listen to music and comes with many other options.

Amazon has been designed by Amazon secretive Lab126. It can listen to voice commands and provide contextual responses. Alexa can help you create to do lists, control smart home products and play Spotify playlist tracks,

Alexa has become popular through its use in Amazon Echo. This device acts as both a smart home hub and a speaker and can also work with many other devices. Since Alexa is a cloud based service, it’s constantly being updated to be more intelligent. As machine learning develops, Alexa can be expected to become more intelligent. Some third-party apps have been allowed to integrate with third party devices to broaden the appeal of Alexa.
