Abstract

Abstract The rapid development of information technology has fostered more natural human–computer interaction through voice assistant technology. This study aims to design and implement Rahayu – Voice Assistant, an Android-based application capable of understanding user voice commands and providing real-time responses. The application employs the SpeechRecognizer API to convert speech into text, the TextToSpeech API to generate voice feedback, and integrates YouTube and Wikipedia APIs to deliver contextual information. The research method includes system design, development of a chat-based interface using RecyclerView, and functionality testing through Black Box Testing. The results show that the application can recognize basic commands with high success rates under clear and stable audio conditions. The system provides a natural two-way interaction and performs well on mid-range Android devices. This research serves as a practical implementation example of integrating speech recognition, simple natural language processing, and text-to-speech in mobile application development.
