There have been speaking computers for years, but now you can call a company and speak totally to a computer. Technology has made it so that it can listen and react somewhat with what you say.

Many times the voices are recorded and a computer then replays it and uses it's own voice. It sounds choppy and very machine like.

Now, there are programs that will take the voice and use it. It will bank words and phrases and the use them to speak. The voice talents are told not to act but to be themselves. That way they can record everything they need to use for a couple of years.

Then other programs can take language and use it. There is a story in the video that talks about how they are preserving languages by recording all of the language. More and more the machines are starting to sound like a human. You will be shocked when you see this video and see how language and voice programs are evolving with voiceover.
