Voice OTP (One-Time Password) is a security feature that delivers a temporary password via an automated voice call. This method adds an extra layer of security for user authentication, allowing individuals to verify their identity by receiving a spoken code over the phone. Here’s a detailed overview of Voice OTP, its working mechanism, benefits, use cases, and best practices.

How Voice OTP Works
- User Request:
- The user initiates an action that requires authentication, such as logging into an account, completing a transaction, or resetting a password.
- OTP Generation:
- The system generates a random one-time password, which is typically a numeric code (e.g., a six-digit number) valid for a short period.
- Voice Call Initiation:
- The system places a voice call to the user’s registered phone number.
- Code Delivery:
- During the call, the system reads the Voice OTP aloud to the user. This can be done using text-to-speech technology or pre-recorded messages.
- User Input:
- The user listens to the code, notes it down, and then enters it into the required field on the website or application.
- Code Verification:
- The system verifies the entered OTP against the generated code to authenticate the user. If the codes match and are still valid, access is granted; if not, the user is prompted to try again or request a new OTP.
