Virtual Assistant

A virtual assistant is a software agent that can perform tasks or services for an individual. Sometimes the term “chatbot” is used to refer to virtual assistants generally or specifically those accessed by online chat (or in some cases online chat programs that are for entertainment and not useful purposes).

As of 2017, the capabilities and usage of virtual assistants is expanding rapidly, with new products entering the market. An online poll in May 2017 found the most widely used in the US were Apple’s Siri (34%), Google Assistant (19%), Amazon Alexa (6%), and Microsoft Cortana(4%). Facebook’s M is expected to be available to hundreds of millions on Facebook Messenger in 2017.

 

Cortana

Cortana is an operating system-oriented voice assistant available on Windows 10 devices, as well as the Xbox One console. Cortana is closely connected to productivity, but can also help answer more general questions by pulling information from Bing.

The Cortana VA has seen a lot of recent growth, expanding her use throughout Windows 10 and related services. Combined with newer offerings like Surface Studio, its clear Microsoft favors Cortana as an OS-based service to control Windows 10 while one is working.

While user can store specific bits of information with Cortana, Microsoft’s virtual assistant is constantly analyzing user’s interactions to learn more about him/her. This info is stored in something Microsoft calls the “Notebook,” which includes the places user likes to go, people he/she care about, user’s preferred quiet hours, and things he/she might be interested in, among other things. User can even edit it if he like.

Cortana can user’s emails, track user’s location, watch user’s browsing history, check user’s contact list, keep an eye on user’s calendar, and put all this data together to suggest useful info, if user allow it to. Cortana is designed to recognize context, so it should be able to understand follow-up requests, and you can phrase things in different ways and still expect a useful answer. User can also type his/her questions or requests, if you prefer to not speak out loud.

The latest changes from the Windows 10 Creators Update allow Cortana to help in the setup process for new computers, and include a new full screen mode for Cortana that serves as both a screensaver and voice-assistant focused mode when user is away from the computer—or is too far away to type. Cortana can also handle music and reminder commands more effectively, spanning multiple music apps and controlling volume as user desire.

 

Siri

Siri has been an integral part of iOS since the launch of iOS 5 in 2011. It started with the basics such as weather and messaging, but has expanded greatly since then to support more third-party integration with MacOS.

While Siri’s jokes are legendary, the virtual assistant is getting more capable every day. Now, user can ask it to call people, send messages, schedule meetings, launch apps and games, play music, answer questions, set reminders, and provide weather forecasts.

Siri can also integrate with third-party apps and understand follow-up queries. That’s a big change in strategy for Apple, which typically maintains a tight grip on which third-party companies get access to its native functions.

Siri is probably the most familiar of all the voice assistants. It also lags behind the other VAs when it comes to text input, which isn’t supported for most Siri functions. Apple appears to be using Siri for voice controls and Spotlight for similar text-based queries.

The latest news for Siri includes voice compatibility for WhatsApp, expanded payment options for Lyft and Uber, and the ability to look up international cricket scores. These are minor tweaks compared to the changes other VAs are going through, but they also point to Siri’s continued stability—particularly for long-term iOS users who already know the voice assistant well.

 

Google Assistant

Google Assistant (which has incorporated functions from the older Google Now, as Now is being phased out) is different from Cortana and Siri. It has less personality, but more functionality. While it is an integral part of Android, Google Assistant also lives in an iOS app, and can be accessed through the Chrome browser as needed.

Like Cortana and Siri, you can ask Assistant for directions to the closest Chinese restaurant, or what the weather looks like for the next 10 days. If you let it, Google’s software will utilize your search history and customize its responses based on what it knows about your queries.

Google’s integration with its search engine makes Google Assistant one of the most useful virtual assistants out of the box. It already has a treasure trove of data on what you’ve done on the web. It also reacts to questions in a similar way to the Google browser, which makes it great for general information and trivia.

 

Alexa

It is Amazon’s voice assistant and it isn’t focused on mobile or computer purposes, but rather for the standalone Amazon Echo speaker and a limited number of Amazon Fire devices, with a greater concentration on whole-house management and services rather than computer-oriented tasks.

Obviously, this limits Alexa compared to the alternatives. However, there are some advantages to the Amazon approach. Like Assistant, Alexa is highly conversational, and its ability to parse meaning is frequently excellent, whether you’re asking about the weather or listening to the latest news summaries from around the web. Alexa is meant to be used out in the open, away from the computer, while you’re working elsewhere but still need information, entertainment, or purchases.

The customization and management options for Alexa also impress. While other voice assistants hide many of their capabilities away from users, Alexa brings them all out in the form of “skills” and connections. The Alexa app allows you to add various mini-apps in the form of skills, and adjust current services and settings using these skills. It’s a great system, especially for those who like to tinker, but it does require learning a new approach to VA management.

Amazon is also doing a lot of work to bring Alexa into more mobile situations: The Alexa app, for example, brings many of its capabilities to your phone so you can organize lists while driving or control smart home features away from an Echo.

 

 

Bixby

Not to be outdone in the voice assistant game, Samsung has also created a mobile device assistant called Bixby, which now has full voice command compatibility (if you’ve picked up a Galaxy S8, you’ve probably encountered it). In general, Bixby shares a lot in common with Cortana. The VA lingers on the Galaxy phone, ready to access information and manage your data, schedule, events, and more. It doesn’t venture out into the Internet of Things much, but it does have an impressive amount of control over everything you do on your Samsung device.

You can divide Bixby into three basic different categories of abilities—Voice, Home, and Vision. They all work together, but use different Bixby abilities:

Voice includes both questions—”What’s the weather today?”—and commands. Start by saying “Hey Bixby” and you can get general information or facts. However, like Cortana, Bixby also excels at operating software, so you can also use it to control the Galaxy menus, change settings, set reminders, take pictures, edit video, and much, much more. If you’ve ever wanted to operate your smartphone hands free, there’s a lot to explore here. Some functionality goes even deeper – you can ask Bixby to read out your latest emails, or tell it to post your photo to Instagram, and Bixby will do so.

Home is the app face of Bixby, a screen that provides information based on what you have asked Bixby about in the past, as well as the different services that Bixby can control with the right compatibility—Including Facebook, CNN, and Spotify. In the future this area may include smart home capabilities (Samsung says it’s on the way), but for now it’s relegated to basic online services.

Vision is the most unique part of Bixby, as it can analyze what image the camera is picking up and give you a report on it. When this works (say, looking at a recognizable logo) Bixby can help you instantly compare online prices to in-store prices, or give you more information about local landmarks. If this feature takes off, other voice assistants may start getting jealous.
