Voice AuthenticationExplore cost-effective, conversion-boosting voice verification methods that offer extensive reach. At LANCK, our goal is to enhance your customer experience while streamlining processes and optimizing budgets..
Choose Your Voice Verification Scenario
Voice OTPs
Voice OTPs (One-Time Passwords) deliver codes to users via telephone calls that transmit a spoken message containing a set of digits. By implementing them, enterprises can provide a foolproof layer of client protection while maintaining a fast authentication process.
Flash Calls
Flash Calls use a short call that doesn’t require the user to answer, delivering a code as the last 4 to 6 digits of the incoming caller number. This method enables immediate verification for enterprises seeking efficiency.
