Smart Home Speech Control System

Če so bile tehnologije pametnih hiš pred nekaj desetletji še znanstvena fantastika, so zdaj prisotne že skoraj v vsakem domu. V uvodnem delu naloge so predstavljeni razvoj koncepta pametnih hiš, njegove prednosti in slabosti ter vpliv na naše bivanje. V praktičnem delu je opisan razvoj prototipnega sistema, ki temelji na razpoznavanju govora. Rezultat našega dela hkrati dokazuje, da je z nekaj računalniškega znanja in cenovno ugodnih komponent mogoče sestaviti in razviti svojo rešitev za govorno upravljanje pametne hiše, ki je prilagodljiva in omogoča nadgradnje. Osrednji del sistema je sestavljen iz mikrokrmilnika Arduino in aparaturnega modula za razpoznavanje govora, ki deluje na osnovi akustične analize zvoka. Ko je govorni ukaz razpoznan, se izvede določena akcija. Delovanje prototipa je preizkušeno in primerjano z obstoječo sorodno rešitvijo. Dosegli smo, da so govorjeni ukazi dobro razpoznani in lahko prožijo ustrezna dejanja v pametni hiši. Kot posebna dosežka lahko označimo tudi enostavnost uporabe prototipa in njegovo zadovoljivo primerljivost s precej dražjimi sorodnimi rešitvami.If technologies for smart houses were science fiction decades ago, today they are present in almost every home. In the thesis, we present the evolution of the smart house concept, its advantages and disadvantages, and its impact on our lives. The practical part describes the development of a prototype system based on speech recognition. At the same time, the result of our work proves that with some computer knowledge and inexpensive components, it is possible to assemble and develop our own smart home voice management solution that is flexible and allows further upgrades. The central part of the system consists of an Arduino microcontroller and the speech recognition hardware module based on acoustic sound analysis. Once the voice command is recognized, a predefined action is executed. The operation of the prototype was tested and compared with the existing related solution. We have achieved that spoken commands are well recognized and can trigger appropriate actions in the smart house. Ease of use of the prototype and its acceptable comparability with much more expensive related solutions can also be considered remarkable achievements
