QIRABOX: Kontrol Speaker Murottal Al-Qur’an dengan Perintah Suara Berbasis Internet of Things

This study aims to design and implement a Quranic murottal speaker control system based on the Internet of Things (IoT), operated through voice commands, with a focus on the needs of visually impaired individuals. The system integrates speech recognition technology with the Aho-Corasick algorithm for command pattern matching and utilizes the MQTT protocol and ESP32 microcontroller as the main control unit. An Android application called "QIRABOX" was developed as the user interface, leveraging Google Speech Recognition to convert voice commands into text. Evaluation involving 10 visually impaired respondents showed an error rate of only 2% and a System Usability Scale (SUS) score of 78.75, classified as "Good." These results indicate that a voice-controlled system can be an effective solution in the development of assistive technology to improve accessibility for people with visual disabilities.
