Virtual assistants make work via:

Some virtual assistants are accessible via multiple methods, such as Google Assistant via chat on the Google Allo app and via voice on Google Home smart speakers.

Virtual assistants use natural language processing (NLP) to match user text or voice input to executable commands. Many continually learn using artificial intelligence techniques including machine learning.

Devices and objects where found

Virtual assistants may be integrated into many types of platforms or, like Amazon Alexa, across several of them:

Services

Virtual assistants can provide a wide variety of services, and particularly those from Amazon Alexa and Google Assistant grow by the day. These include:[10]

  • Provide information such as weather, facts from e.g. Wikipedia or IMDB, set an alarm, to-do lists, shopping lists,
  • Play music from streaming services such as Spotify and Pandora; play radio stations; read audiobooks
  • Play videos, tv shows or movies on televisions, streaming from e.g. Netflix
  • Buy items from e.g. Amazon
  • Complement and/or replace customer service by humans.[11] One report estimated that an automated online assistant produced a 30% decrease in the work-load for a human-provided call centre.[12]

Third-party services

Amazon enables Alexa "Skills" and Google "Actions", essentially apps that run on the assistant platforms.

Developer platforms

The platforms that power the most widely used virtual assistants are also used to power other solutions:

  • Amazon Lex was opened to developers in April 2017. It involves natural language understanding technology combined with automatic speech recognition and had been introduced in November 2016.[13]
  • Google provides the Actions on Google and API.ai platforms for developers to create "Actions" for Google Assistant[14]
  • Apple provides SiriKit for developers to create extensions for Siri
  • IBM's Watson, while sometimes spoken of as a virtual assistant is in fact an entire artificial intelligence platform and community powering some virtual assistants, chatbots. and many other types of solutions.[15]

Previous generations

In previous generations of text chat-based virtual assistants, the assistant was often represented by an avatar of (a.k.a. 'interactive online character or automated character) -- this was known as an embodied agent.
