The Rise of Voice-Based Payment Systems: A Convenient and Secure Future


In recent years, technological advancements have significantly transformed the way we interact with financial services. Among these innovations, voice-based payment systems have emerged as a promising and convenient means of conducting transactions. By leveraging the power of artificial intelligence (AI) and natural language processing (NLP), these systems allow users to make payments using voice commands, eliminating the need for physical cash or even traditional digital payment methods. This article explores the growing popularity of voice-based payment systems, their benefits, security considerations, and their potential to revolutionize the future of commerce.

The Emergence of Voice-Based Payment Systems

Voice-based payment systems have gained momentum due to the rapid proliferation of voice-activated devices such as smart speakers, smartphones, and wearable devices. Market leaders like Amazon’s Alexa, Apple’s Siri, Google Assistant, and others have integrated payment functionalities into their voice assistants, making it easier for users to initiate payments by simply speaking their commands.

How Do Voice Payments Work?

A voice-based payment involves interacting with an AI-powered device, like a speaker or smartphone, by speaking to it and instructing it to carry out a transaction. Subsequently, the device identifies and comprehends the spoken request, takes action accordingly, and responds by confirming the transaction.

The concept of voice payments emerges from progress achieved in artificial intelligence (AI) and machine learning (ML). AI denotes the capacity of machines to execute tasks that typically demand human intelligence. Meanwhile, ML, a subset of AI, enables machines to learn from data without explicit programming.

Furthermore, voice-based payments leverage natural language processing (NLP), an AI branch enabling computers to grasp, communicate in, and generate human languages. This technology collaborates closely with voice recognition engines. For instance, voice assistants like Amazon’s Alexa or Apple’s Siri employ AI-empowered voice recognition tech, which transforms human speech from analog to digital format. The machine then captures, comprehends, interprets, and executes the spoken directives. Consequently, NLP stands as a critical element facilitating the feasibility of voice payments.

Procedure for Making Voice Payments

Establishing a voice payment account bears resemblance to creating an online wallet. The procedure for setting up a voice payment account closely mirrors that of initiating a payment through an online wallet. In both instances, the user associates their credit card, debit card, or bank account particulars with their device. However, in the context of voice payments, the user is spared from the need to launch an application and manually input payment details. Instead, they instruct their device to execute the payment via voice command.

Upon verbalizing the command, the device accesses the payment application and seeks confirmation from the user. To validate the payment, the user can utilize a password, facial recognition, or a fingerprint scan. The process operates conversely as well. For instance, one can instruct their device to request funds from another individual.

Moreover, voice payments are anticipated to equalize access to the expanding online payments sector. Individuals using any type of mobile device, whether it’s a basic feature phone or a smartphone, can conduct transactions using voice commands through an IVR-equipped call-based payment system. The process is as straightforward as dialing a phone number.

This technology also empowers consumers to verify their account balances and oversee their financial transactions.

 Use Cases of Voice Based Payments

In today’s fast-paced world, many consumers are adopting voice commands, including voice-based payments, due to their convenience. Mobile payment platforms like Venmo, Square Cash, and PayPal enable voice-initiated peer-to-peer transfers. Traditional banks like Wells Fargo are also integrating conversational voice interfaces into their mobile banking apps.

Additionally, shoppers can utilize voice-enabled credit card apps to make purchases online or in stores, known as voice shopping. Google partnered with Carrefour France to launch a voice-activated grocery shopping service, with plans to expand to 30 more countries. This innovative payment method, developed jointly over three years, allows customers to connect their bank accounts to Google Assistant, verbally add items to their cart, and effortlessly complete the payment via voice commands.

Several banks, such as Barclays and Royal Bank of Canada, among others, have started offering voice-enabled peer-to-peer payments to their customers. Barclays allows its customers to make voice-based payments using Siri, the virtual assistant offered as part of Apple Inc.’s operating systems. Similarly, Google Assistant allows Google Pay users to make peer-to-peer payments using voice commands.

Reserve Bank of India has recently unveiled a plan for “conversational” payments, allowing UPI users to make verbal transfer instructions on their phones which will be processed using AI-based speech recognition.The NPCI, the platform for operating retail payments and settlement systems in India is working with AI4Bharat, an open-source language artificial intelligence (AI) centre based at the Indian Institute of Technology (IIT), Madras, to facilitate voice-based merchant payments as well as peer-to-peer transactions in local languages.The language model for this system will be provided by AI4Bharat.

The central bank says users without internet access will be able to make transactions using near field communication technology, allowing for retail digital payments in situations where internet or telecom connectivity is weak or not available.

The Reserve Bank of India, in its monetary policy statement in August 2023, proposed the launch of conversational payments on UPI. This will be an AI-powered system through which consumers will be able to have a conversation and initiate and close a transaction.Amazon Pay already supports voice based bill payments through Alexa commands.

AI voice bots will soon facilitate UPI transactions through interactive conversations, making UPI accessible for individuals from diverse backgrounds to manage their everyday financial dealings.The National Payments Corporation of India (NPCI) is building a voice bot based interactive system for Indian consumers to make payments via UPI.The idea is to build an Amazon Alexa type voice system into which payment apps and banks can integrate. Consumers who have to undertake multiple steps to make payments via UPI will be able to just speak into the app.
