As these technologies continue to evolve, financial institutions and fintechs are trying hard to include voice authentication in their services, allowing voices to act similarly to other biometrics, like fingerprint or facial recognition.
According to a report by MarketsandMarkets, the global voice recognition market size was valued at $9.27 billion in 2020 and is projected to reach $27.16 billion by 2025, growing at a CAGR of 23% during the forecasted period.
"Voice biometrics has the potential to eliminate passwords altogether, making the customer experience more secure and seamless." - Brett Beranek, Vice President of Biometric Technology at Nuance Communications.
In 2022, there were around 142 million users of voice assistants in the US alone, according to Statista, which shows just how familiar people are becoming with this technology.
In a survey conducted by Pindrop, 60% of respondents reported using voice recognition technology at least once a month, with 77% using it on their smartphones. Voice authentication now includes a wide range of technologies that revolve around correctly responding to and recognizing a user’s voice. While using your voice to communicate with Alexa, Siri, and Google Assistant is straightforward, utilizing this technology for transaction authentication still has not reached its full potential.
Voice authentication is a biometric method that uniquely identifies users by measuring the distinctions in their voices, offering a secure alternative to traditional passwords. By analyzing over 70 parts involved in speech production, voice recognition technology digitizes speech to create a template or voice print that can later be used as a password.
The standard voice print consists of formants and dominant frequencies representing spoken word segments. After they've been recorded, these unique voice prints are securely stored in databases (like fingerprint and facial scans). Every time individuals recite a specific text or passphrase, they create a high-quality voice print, allowing the system to capture their unique vocal characteristics and recognize their voice in the future.
This process is similar to scanning all angles of a fingerprint on a touchpad. When the user subsequently utilizes the passphrase, specific words are compared with the stored voice print to authenticate their identity.
There are a few unique characteristics that must be highlighted when it comes to recognizing the uniqueness of one's voice: inflection, speech rate, clarity, brevity, and emotional mood.
Some voice authentication systems differ in that they do not rely on pre-recorded voice samples. Instead, they are trained to recognize similarities between individuals' voice patterns, enhancing the adaptability and flexibility of the technology. Here's how voice authentication works:
Overall, voice authentication harnesses the distinct characteristics of an individual's voice, offering a robust and secure method for user identification and access control.
Voice recognition technology has rapidly expanded its applications with the advancement of AI, machine learning, and increased user acceptance. Here are several examples of voice recognition's diverse uses:
Biometric Verification: Voice authentication is considered a form of biometric verification, as it relies on unique physiological and behavioral characteristics of an individual's voice.
Security and Fraud Prevention: Voice authentication adds an extra layer of security to financial transactions by reducing the risk of identity theft, fraud, and unauthorized access. It helps ensure that only authorized individuals can access sensitive financial information or perform transactions.
Voiceprint Creation: To use voice authentication, users typically need to enroll by creating a voiceprint. This involves recording a sample of their voice, which is then converted into a unique digital representation based on specific voice characteristics.
Continuous Authentication: Voice authentication can also be used for continuous authentication during a conversation or interaction with a financial service provider. The system can monitor the ongoing conversation to ensure that the voice characteristics remain consistent and match the original voiceprint.
The wide-ranging adoption of voice recognition technology in finance showcases its versatility and practicality across various domains, enriching user experiences and facilitating efficient communication and control.
Since the technology has matured enough to become a standard in mobile phones, computers, and other devices, the financial sector realized the plethora of benefits the technology could bring in two distinct use cases: voice-driven customer service and voice-enabled payments.
