At Film critic Roger Ebert has been unable to speak with his own voice since 2006, when he underwent surgery related to his battle with thyroid cancer. Since then, he’s been using a computerized voice (notably, “Alex,” a voice built-in to Mac OS X), to communicate all this time. But today on Oprah, he’s debuting a new computerized voice: his own. If you watch the video at the bottom of this post, it’s pretty remarkable just how much it sounds like Ebert. He has a distinctive voice that a lot of his fans know well thanks to his many years on television reviewing films.
