In this century, vending machine has become a trend of a model for the business markets. Many types of vending machines have been developed such as beverage vending machine, cigarettes in vending machine, snacks in vending machine and so on. Hence, the vending machine business has proved that it is a profitable business in this era, yet maintenance plays the important role for the vending machine. There are plenty of problems that human facing difficulties in using the vending machine like coin or note cannot be read, vending machine jamming issue or sufficient change is not available. In this project, speech recognition is implemented in the vending machine to overcome the variety problems of the vending machine. Basically, speech recognition is a common tool of communication for humans. Speech recognition has the ability to identify the spoken language which is in the form of digital signals and convert it to machine readable format. This speech recognition vending machine consists of hardware and software parts. Visual Studio and Arduino software are used to perform analysis and coding. Coding in Visual Studio Software is mainly to perform speech recognition function while the coding for Arduino Software is used to trigger the hardware. The hardware parts included breadboard with some circuits, Arduino Uno microcontroller and DC motors. Moreover, the accuracy result for the speech recognition can also obtain by using the Visual Studio software. The accuracy results have been collected to prove the sensitivity for the speech recognizes engine by using human speech test. The purpose of implementing the speech recognition vending machine is to bring convenience and time saving for users. This speech recognition vending machine does not require any coin or note to buy the beverage. Hence, it is suitable to be installed in a small company which the company wishes to contribute some benefits and encouragement to the worker by giving free beverages or more. Instead of facing the problems of coin or note rejected, users only have to speak the types and name of the drinks and the speech recognition vending machine will perform the required action.
