Delivery monitoring system for teachers' voice in traditional classrooms and automatic controlling system in smart/remote classrooms

Teaching is one of the essential elements, which impact the learning process. An effective teaching happens only if the students can hear and grasp what is taught clearly. In a classroom, teachers' voice quality will greatly affect the students' comprehensibility and interest in learning. So teachers should make sure that every student in the classroom could hear the voice in clear, precise and audible manner. This paper introduces a system that monitors the delivery of teachers' voice in classrooms and indicates the teachers if the voice could not be heard at some part of the traditional classroom (classrooms without speakers). In smart or remote classrooms, where multiple speakers are integrated, the system automatically controls the volume of the speakers to the adequate level so that every student is able to hear the teacher. The paper also involves research study and survey to identify the influence of teachers' voice on learners. Results from this study show that efficient lecture delivery helps students to improve their learning ability.
