Automatic Control Based on Voice Commands and Arduino

摘要

Control that is widely used today was control by voice commands. This study aimed to determine the application of voice and Arduino-based control automation which had been developed from 2014-2020 based on 25 journals that would be studied. Journal assessments were carried out by taking into account the similarities or differences in each journal. The research method used in this research was literature review by reviewing 25 journals. The results obtained from the journal review showed that the developed voice control consists of 2 types, namely voice recognition and speech recognition. Voice recognition used an easy VR hardware device and a microcontroller, while speech recognition used an application installed on Android, controlling can also be done remotely using Bluetooth and the internet. The way the voice control system works was that the user given voice commands via a microphone, then the command would be converted by the voice control module on the Easy VR module or the voice recognition module. The conversion results were sent to the microprocessor and activate the controlled device. Whereas in remote control, the data resulting from the conversion was also sent to the bluetooth module or NodeMCU module which was sent to the microprocessor to activate the controlled device. The factors that affect the voice control system were clear pronunciation, pitch and sound, microphone distance, sound source, intonation and noise level.
