Amazon Connect Voice ID

Real-time caller authentication and fraud risk detection using ML-powered voice analysis

Amazon Connect Voice ID, a feature of Amazon Connect, uses machine learning to provide real-time caller authentication and fraud risk detection to make voice interactions faster and more secure. Historically, contact centers have used a time-consuming knowledge-based authentication process where callers have to answer multiple questions based on personal details, like social security number, date of birth, and mother’s maiden name. Amazon Connect Voice ID analyzes caller's unique voice characteristic to provide agents and self-service interactive voice response (IVR) systems with a real-time decision on caller's identity for faster and more accurate verification at a very low cost. Amazon Connect Voice ID also screens for fraudulent actors in real-time, based on your contact center’s custom watchlist, reducing potential losses from fraudulent attacks.

Easy customer enrollment and verification

When a customer agrees to enroll, Voice ID analyzes speech attributes like rhythm, pitch, and tone to create a digital voiceprint, streamlining the authentication experience for customers on their next call. Customers don’t have to say any specific phrases or words, allowing them to maintain the natural flow of conversation. 

ML-powered real-time fraud risk detection

Voice ID analyzes incoming audio and compares them with recordings of known fraudulent actors in your contact center's custom watchlist. During an active call, Voice ID will automatically flag suspicious callers to the agent with a risk threshold (e.g. 'High Risk or 'Low Risk,') — resulting fewer fraudulent attacks on your contact center.

Simple to setup and configure

You can easily setup and configure voice biometrics for your Amazon Connect Instance. First, enable Voice ID in the AWS Console for your Amazon Connect Instance and then easily configure authentication and fraud risk detection using the drag-and-drop functionality of Contact Flow blocks.

Build a highly efficient and secure IVR

Add Voice ID to your IVR to deliver secure customer access to self-service requests such as checking refund status or changing contact information. This optimizes agent time and lowers contact center costs.

Businesses can use Voice ID’s authentication score to create policies for providing a decision ('authenticated' or 'not authenticated'). When Amazon Connect Voice ID does not have the required amount of speech or historical voiceprint data to provide an authentication score, it will return a result of "inconclusive". Businesses can choose to use other multi-factor authentication methods along with Amazon Connect Voice ID to further authenticate the caller. Amazon Connect Voice ID returns a fraud risk score between 0 and 100. A higher risk score indicates that Amazon Connect Voice ID is more confident that the caller’s audio carries a high risk of the call originating from a fraudster in your watchlist.
