Abstract

Background/Objectives: Most colleges and universities in the Philippines consider acquiring a speech laboratory equipment a tough matter to manage due to the prices and after-sales support. Methods/Statistical analysis: Many speech laboratory equipments from abroad exist but would not serve for a long time, particularly in terms of durability and maintainability. Findings: The researcher developed a digital innovation in developing speech laboratory equipment that suitable for the end-user to operate the system quickly using a personal computer (PC). An interface was connecting serial communication via USB port to a Fuzzy Logic Controller to facilitate the switching of speaker and microphone in the student cubicles/headsets in real audio while in peer-to-peer communication. Moreover, the monitor or console of the teacher operates in a more comfortable and user-friendly manner. When the teacher clicks the desired function or button, the Fuzzy Logic Controller module responds and processes the command to enable or disable the student's headset. On the student's side, there is a call button function to highlight the teacher console. Improvements/Applications: Hence, the system is maintainable and flexible that can even run on Windows Operating Systems and Linux.
