Recording of someone's voice... saying what
"Saying what?" You're asking what every possible phrase or word that someone might ever say that could be used to verify the identity to another party or device? Are you on crack?!
Scenario 1: You leave a voice mail on a phone that's turned off. You say "Hey, it's me. Call me back." How does the person know that is you? They recognize your voice.
Scenario 2: You hear a recording of your someone in your family you were close to but it no deceased. You know who it is right away. How did you know? You recognize the voice.
Both scenarios the person who left the message doesn't have to be present or alive, they simply have to have left a recording of their voice. Why are hung up on what one would say is beyond me. If you are looking for some John Edward type shit I'm not the person you should speak to.
Clearly the computer would have you read a specific text in order for the ID to work. You can't feasibly have naturally sounding samples of any possible sentence.
And if it's a specific text then you have to assume that text was spoken before. That means if the text was recorded then you can use that recording to trick the system. You can also use partials to create the full text well enough to trick the system. My question to you is how does it know you are not alive? Do you think there are implants in the heart that will send a message to the system to disable a voice if your heart stops? There isn't. That's science fiction.
