Implementation of Google Home voice assistant
Matula, Vladimír ; Štůsek, Martin (oponent) ; Zeman, Kryštof (vedoucí práce)
The main goal of this bachelor thesis was to investigate the smart devices field together with technologies linked to it. Further, it describes the implementation of Google Assistant to Raspberry Pi 3 and options of controlling it via the Dialogflow platform. The thesis provides hands-on experience and is structured into two parts. The first, theoretical section focuses on Internet of Things and Device to Device communication. It also describes currently available smart home assistants and their functionalities. The thesis also describes the Dialogflow platform together with it's functionalities and options of it's use. The practical part of this thesis describes implementation of the Google Assistant in Raspberry Pi 3, development and integration of application created for it and the creation of home weather station.

Resilience of Biometric Authentication of Voice Assistants against Deepfakes
Šandor, Oskar ; Firc, Anton (oponent) ; Malinka, Kamil (vedoucí práce)
With the rise of deepfake technology, imitating the voice of strangers has become a lot easier. It is no longer necessary to have a professional impersonator to imitate the voice of a person to possibly deceive a human or machine. Attackers only need a few recordings of a person's voice, regardless of the content, to create a voice clone using online or open-source tools. In that case, he or she can create recordings with content that the person may have never said. These recordings can be misused, for example, for unauthorized use of voice-assistant devices. The aim of this work is to determine whether voice assistants can recognize synthetized recordings (deepfakes). Experiments conducted in this thesis show that deepfakes created in a matter of minutes can spoof speaker recognition in voice assistants and can be used to carry out several attacks.
