The need for a computerized language laboratory isstill imperative since most schools and universitiesare going into computerization and user-friendlytechnology, however, the cost of producing suchfacility is still very expensive and may run to millions

considering the state of the art involved. The localexperts at West Visayas State University havedeveloped such system at a much lower cost.

Most importantly, such lab in the modern day BPOs

and call centers will boosts the local industry interms of technicalities.

Students are equipped with a professional audio panel softwarewhich provides stable and lasting quality professional audio,ideal for enhancing communication and audio recording during

their digital labs. The system, with its user-friendly interface,allows the teacher to create multiple classes without the worryof facing difficult tasks because each type of activity is guidedchoice.

"One main advantage of SpeechMaster-PCPS Digital Language

Lab is that teachers can send data to students / terminal and cancopy any file type (audio, video, images or text) directly on to aUSB memory stick connected to the Student's of SpeechMaster-PCPS Digital Panel, in order to assign tasks to be completedoutside the language laboratory."

A tool designed and built for teaching and learning foreignlanguages, it enhances oral communication and allow simplelinguistic exercises, reproducing typical everyday situations.

With SpeechMaster-PCPS renders the ordinary language laboratory

a perfect place for communicating and exchanging knowledgebetween teacher and students.

The completely graphical 'user-friendly' graphical interface makesSpeechMaster-PCPS a simple and immediate tool from first use andlessons with a class. SpeechMaster-PCPS is f lexible and modularallowing the upgrade and expansion from audio-active to audio-active-comparative, and also to audio-visual by adding an external

video network, without wasting any part purchased.

Easy to operate because it is software base no any

proprietary hard ware required. No additional gadgetrequired.

As long as there is a desktop PC available in the market thesoft ware will run.

Current language lab system requires proprietaryhardware and other devises needed for the set-up. Theproblem is maintenance and support of the equipment.

The locally-made digital language laboratory enablesthe University to develop is very own language facilityand is designed to be user friendly as well as a cheaperand innovative system made available to local

conditions including the upgrading of the hardwareand software. The language laboratory which will bedeveloped in collaboration with local languageexperts can be fully developed or customizedaccording to the needs of the local clients as well asstudents of various intellectual levels. The system isnot dependent on proprietary hardware, meaning aslong as desktop pc is available in the market thesystem can still exist .
