Virtual assistants use natural language processing (NLP) to match user text or voice input to executable commands. Some virtual assistants are accessible via multiple methods, such as Google Assistant via chat on the Google Allo and Google Messages app and via voice on Google Home smart speakers. By taking and/or uploading images, as in the case of Samsung Bixby on the Samsung Galaxy S8.Voice, for example with Amazon Alexa on the Amazon Echo device, Siri on an iPhone, or Google Assistant on Google-enabled/ Android mobile devices.Text ( online chat), especially in an instant messaging app or other app.developed Siri following the 2010 acquisition of Siri Inc., a spin-off of SRI International, which is a research institute financed by DARPA and the United States Department of Defense. The first modern digital virtual assistant installed on a smartphone was Siri, which was introduced as a feature of the iPhone 4S on October 4, 2011. Much later the market launch of the first smartphone IBM Simon in 1994 laid the foundation for smart virtual assistants as we know them today. In the 1990s digital speech recognition technology became a feature of the personal computer with Microsoft, IBM, Philips and Lernout & Hauspie fighting for customers. Thus, the earliest virtual assistants, which applied speech recognition software were automated attendant and medical digital dictation software. About ten years later the same group of scientists developed a system that could analyze not only individual words but entire word sequences enabled by a Hidden Markov Model. Their tool "Harpy" mastered about 1000 words, the vocabulary of a three-year-old. The next milestone in the development of voice recognition technology was achieved in the 1970s at the Carnegie Mellon University in Pittsburgh, Pennsylvania with substantial support of the United States Department of Defense and its DARPA agency. This early computer, developed almost 20 years before the introduction of the first IBM Personal Computer in 1981, was able to recognize 16 spoken words and the digits 0 to 9. The first tool enabled to perform digital speech recognition was the IBM Shoebox, presented to the general public during the 1962 Seattle World's Fair after its initial market launch in 1961. Amazon has a large install base for smart speakers. Microsoft has a large installed base of Windows-based personal computers, smartphones and smart speakers. Apple and Google have large installed bases of users on smartphones. Īs of 2017, the capabilities and usage of virtual assistants are expanding rapidly, with new products entering the market and a strong emphasis on voice user interfaces. Users can ask their assistants questions, control home automation devices and media playback via voice, and manage other basic tasks such as email, to-do lists, and calendars with verbal commands. Some virtual assistants are able to interpret human speech and respond via synthesized voices. Sometimes the term " chatbot" is used to refer to virtual assistants generally or specifically accessed by online chat (or in some cases online chat programs that are exclusively for entertainment purposes).
