Inventions and innovations are the two major reasons of the rising technology that we are experiencing nowadays. As the technology moves forward, it is inevitable that automatic switching has become a need in providing efficient controls.

The purpose of the study is to develop a device that will provide switching of electrical devices through speech recognition technology. The device is composed of PIC Micro 16F84 interfaced to the 74154 Controlling Integrated Circuit in operating the speech recognition device using Microphone and HM2007 integrated circuit.

Based from the result of the evaluation conducted in terms of usefulness, operability, performance, reliability, appearance, portability and safety, the overall score shows an outstanding rating. This rating shows that the developed device is effective in providing automatic switching.

The development of Remote Control made a great impact to the competitive world of technology; it was phenomenal. The researchers declare it as one of the inventions that really gave justice to the thought that "TECHNOLOGY MAKES LIFE EASY". It had contributed much to the rapid growth of our busy living, thus it was accepted worldwide. In fact, this has been a catalyst for industries to produce home appliances and devices with remote controls. For the researchers, watching television wouldn't be that relaxing without remote control. Imagine how inconvenient is to switch channels without remote controls? Definitely it really served the need of every individual.

But in this fast changing world of ours, it is undeniable that remote controls are not that sufficient to comply with our needs. Take a look at some of the given situations. Imagine if you are in an office typing immediate reports for your boss then you are also ask to open the doors; receive fax; switch on the lights, air conditions and other electrical devices. Another situation, you are in the kitchen and cooking some dishes and you want to turn on your television and turn off the music on next room while you saute the food without leaving your stove on. These situations call for a multi-tasked device where in you can do these tasks at the same time without interruptions.

In view of those situations, the researchers were motivated to conduct this study. Sensors came out as the first option but presently sensors are already popular in the market and commonly used in the industry. So another idea came out, Sound or Speech Recognition Circuits influenced by voice tags, a special feature of Nokia cellular phones. With that thought, a Speech Recognition Circuit for controlling and switching devices for an office was conceptualized. This is an easy and efficient switching system which is truly a technology that will make our task easy and comfortable.

In the near future, the researchers believe that speech will be the method for controlling appliances, toys, tools, computers and robots. There is a huge commercial market waiting for this technology to mature. To be able to control and operate an appliance by speaking to it makes it easier to work with the device while increasing the efficiency and effectiveness. At most basic level, speech commands allow the user to perform parallel tasks while continuing to work with other computer appliances and instrument.

With that strong perception, the researchers find it advantageous for a competitive company that offers many services to use this technology. Control offices or server rooms will really appreciate this innovation to have an easy access to controls in their switching system. In residential homes, households can use this for easy access to their appliances even with their hands full.

The primary objective of this study is to develop and construct a Speech Recognition Switching Device using latest Integrated Circuits (IC) and Memory Storing Components such as Static Random Access Memory (SRAM) interfaced to PIC Micro Controlling Circuit.

Specifically, this study aims:

1. To provide speech recognition switching system in an office;

2. To control the power switching and operate electrical devices;

3. To interface PIC Micro 16F84 to the 74154 Controlling Integrated Circuit in operating the speech recognition device using Microphone and HM2007 integrated circuit;

4. To recognize speech or voice signals as input and be converted to a voltage signal to implement a certain switching command.

The study is limited to the development of a speech recognition switching device specifically to on and off electrical devices or close and open electrical connections. This speech recognition device could only accommodate 10 outputs for electrical devices. This device responds only to definite train word or group of words stored in the memory by an individual who will be using the system.
