that extremely short exposures to a relatively simple computer program could induce powerful delusional thinking in quite normal people. Weizenbaum was surprised by this, later writing: "I had not realized. Weizenbaum's own secretary reportedly asked Weizenbaum to leave the room so that she and ELIZA could have a real conversation. ELIZA used pattern matching and substitution methodology into scripted responses to simulate conversation, which gave an illusion of understanding on the part of the program. It was created to "demonstrate that the communication between man and machine was superficial". The first natural language processing computer program or the chatbot ELIZA was developed by MIT professor Joseph Weizenbaum in the 1960s. 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. Īnother early tool which was enabled to perform digital speech recognition was the IBM Shoebox voice-activated calculator, presented to the general public during the 1962 Seattle World's Fair after its initial market launch in 1961. It could therefore be used for voice dialing, but in most cases push-button dialing was cheaper and faster, rather than speaking the consecutive digits. It was limited to accurate recognition of digits spoken by designated talkers. It could recognize the fundamental units of speech, phonemes. It occupied a six- foot-high relay rack, consumed substantial power, had streams of cables and exhibited the myriad maintenance problems associated with complex vacuum-tube circuitry. In 1952 Bell Labs presented “Audrey”, the Automatic Digit Recognition machine. It was a wooden toy in the shape of a dog that would come out of its house when its name is called. Radio Rex was the first voice activated toy released in 1922.

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 both email and voice user interfaces. A similar concept, however with differences, lays under the dialogue systems. 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 (spoken?) commands. Some virtual assistants are able to interpret human speech and respond via synthesized voices. In some cases, online chat programs are exclusively for entertainment purposes. The term " chatbot" is sometimes used to refer to virtual assistants generally or specifically accessed by online chat.
