Design of low cost voice operated vending machine using V3 module

In this project, a low-cost voice operated vending machine (VOVM) is designed using a V3 voice recognition module which is a touchless base vending system. The basic vending machine represents an automatic seller machine where the buyer puts the money in terms of coin or banknote into the vending machine. Then, the required product will be vending out from the machine after selecting the item which is store inside the system. After analysing several vending machines, it is found that the proposed VOVM is more advanced than the other existing vending machine as it can select the items without any contact with the system. This VOVM may also be useful to this current pandemic situation of COVID-19 because of its unique features. The main objective is to upgrade the touchbased vending machine to voice operated system as one can select any items in the vending machine using voice command. This system will make it easier for the user to interact with the machine for everyone and also it can be deployed in every corner of the workplace, hospital, airport, schools, railway station, etc. for selling different kinds of products efficiently.
