Actually, examining Snape's words more carefully than my memory, I think I was simply wrong. Snape says that the 'quality' is something that 'even Legilimency cannot share', and so how did the Dark Lord then verify Snape's memory? He seized Snape's mind with such force and magic that Snape's Occlumency would've been hopeless and instead of perceiving the prophetic quality of voice, he looked for Snape's personal confusion at not understanding the prophecy.

So it seems that Dumbledore could not verify it after all: he could not be sure of breaking Quirrel's Occlumency both out of ethics and because Quirrel seems to be closer to Dumbledore in power than Snape was to Voldemort, and he cannot simply verify the prophetic quality in whatever memory Quirrel chooses to provide.


Which of course still leaves the Hall of Prophecy: surely Quirrel's word about a prophecy of the apocalypse would be worth defying the Department of Mystery over, in order to verify?

To hear the prophecy you need to be mentioned in it. So maybe anyone can hear this prophecy because the end of the world effects everybody. But if not, taking Harry there and him hearing it would be confirmation that its about him.

Though, verification may be a moot point and Dumbledore may already know the prophecy about Harry. After all, Dumbledore heard the end of the prophecy in the dinning hall back when it was "he is coming" rather than "he is here". And Dumbledore also gave excuses not to take Harry into the hall of prophesy

Harry was staring directly at Albus. "Can I go to this Department of Mysteries place and hear the recorded prophecy? The original tone of voice might be helpful, from what I've heard."

Light glinted from the reflection of Albus's half-moon glasses as the old wizard slowly shook his head. "I think that would be unwise," Albus said. "For reasons beyond the obvious. It is dangerous, that place which Merlin made; more dangerous to some people than others.".
