If the Haptek Player is not on your computer (is it possible?), you have to install it before starting. Here >>>
Haptek Player installation
You can choose the voice you want in the Haptek SAPI Config. If you want The Beatles to speak with Michael Jackson' voice, choose a female voice. It's funnier. And if you need voices, see here >>>
TTS voices
And maybe you could use Internet Explorer to be sure that all this works correctly...
IMPORTANT! PLEASE READ THIS BEFORE CLICKING:
When you click the next link for the first time, the new page doesn't work correctly, because of a bad synchronization. So, after loading the elements, YOU MUST RELOAD the page by clicking the title bar and then pressing F5. Then it's OK (I hope so). Now, The Beatles are waiting for you:
THE BEATLES
Many Thanks to JACK GEPHART for The Beatles "skins".
Many Thanks to NIGE for The Beatles hair.
