Our everyday shopping lives have been significantly augmented by rapid advances in Commerce Technologies. Buying and Selling of items as well as payments are currently mostly done online using advanced technologies, which have sped up shopping activities and made lives more comfortable for consumers. In spite of the rise in e-commerce, e-business, internet communication, and payment systems, physical cash is still popularly used in buying and selling of items on the University Campus in Ghana. There is no issue with that. However, a lot more problems surface when the seller has to give change to the buyer. The inconvenience of getting change for buyers especially when the change amount is quite small, such as GHC 20 pesewas is becoming menacing. This project thus seeks to reduce the inconveniency associated with change collection during buying and selling by allowing students and staff to accumulate their change amounts electronically through voice interface systems. This paper presents a comprehensive implementation of the OkNsesa system which comprises of speaker recognition and speech recognition components to allow users update their electronic accounts using voice commands. The key advantage of using voice interfaces is the ability to automatically log users into the system by recognizing who the user is from his voice.
