Continued development of technology led to an increase in performance and decrease in price of electronic devices, which further led to Internet of Things – a term used to describe a multitude of connected embedded devices designed to improve quality of life. These devices can also be found in homes, giving rise to smart homes. Increasingly, the main communication interface in a smart home is a smart speaker. If the user is further away from the device, the quality of communication suffers due to sound deformation. An assumption is made that the quality of communication can be improved by placing devices that contain a microphone inside a room. This thesis presents an implementation of such a device based on Bluetooth technology. Power consumption and connection quality at different distances were measured and tested and acceptable results were obtained.
