If you've ever recorded a podcast or a voiceover, you know how frustrating it can be. One slip of the tongue may force you to chop up your recording, or even redo an entire segment. Adobe believes it has a better solution: change what you said. As part of a trio of experiments, the software pioneer has introduced a VoCo tool that would let you insert dialogue into existing voice recordings. All you need is enough audio for the software to get a sense of someone's voice -- after that, you can type what you want that person to say. The results aren't always perfect in this early software, but they're surprisingly natural-sounding.
