Application of artificial intelligence through virtual voice assistants

U ovome radu cilj je objasniti razvoj i načine upotrebe virtualnih glasovnih asistenata koji se ponekad također nazivaju i inteligentnim osobnim asistentima. Virtualni asistenti su pokretani umjetnom inteligencijom, tj. inteligentnim ponašanjem demonstriranim od strane strojeva, umjesto ljudi i životinja, kao što je to slučaj s prirodnom inteligencijom. Virtualne asistente možemo definirati kao tip softvera koji vrši funkciju prepoznavanja prirodnog jezika (putem glasovnog zapisa ili tekstualnog unosa) i na taj način vrši naredbe zadane od strane korisnika kao što su, na primjer, odgovaranje na pitanja, izvršavanje jednostavnih funkcija na pametnom telefonu ili upravljanje kućanskim aparatima i ostalim uređajima. Virtualni asistenti su danas dostupni ponajviše na pametnim telefonima, ali sve češće se dodaju i televizorima, pametnim zvučnicima, pametnim satovima te osobnim računalima. Nadalje, ovim radom objasnit će se na koji način pojedina tvrtka realizira vlastitog virtualnog asistenta. Tako će biti riječi o Appleovoj Siri, Googleovom Google Assistantu, Microsoftovoj Cortani, Amazonovoj Alexi te Samsungovom Bixbyju.In this work the main point is to explain the development and ways of using virtual voice assistants which are sometimes also referred to as intelligent personal assistants. Virtual assistants are powered by artificial intelligence, i.e. intelligent behaviour showcased by machines instead of humans and animals which is the case for natural intelligence. Virtual assistants can be defined as a type of software which does the function of recognising natural language (either through voice record or text input) and in that way it performs commands given by the user, such as, answering questions, performing simple functions on a smartphone or managing appliances and other home devices. Virtual assistants are available today mostly on smartphones, but they are becoming more and more common on TVs, smart speakers, smart watches as well as personal computers. Furthermore, this work will show how each company makes and manages its own virtual assistant. So there will be a description of Apple’s Siri, Google’s Google Assistant, Microsoft’s Cortana, Amazon’s Alexa and Samsung’s Bixby
