Can voice input as a password be a useful security measure as an alternative to a strong password and biometrics (face, thumb, signature etc)?
The voice inputted as a password will be saved as a sound wave file in the system and while the authenticating end user has to input his voice with the same wordings he / she had spoken while saving the password. In case the system detects the same speech (voice match with his/her saved inputted voice as password), the system will authenticate him to log in to the system.
What are the bottlenecks and limitations to this security authentication measure of voice input?
