textPuppet creates lipsynced pose files, much like Mimic. However, it works entirely from text input alone, and also generates text-to-speech .wav files using a built-in speech synthesizer.

It's a separate utility, not a plugin. You don't even need to have Poser installed in order to use it. The poses should work with any Poser figure that has the proper morphs.

textPuppet is a nice application, but in my opinion Mimic does more convincing lipsyncing. And the speech synthesizer isn't exactly state-of-the-art, although I've heard worse. But the biggest turn-off for me is the fact that I can't use existing .wav files with it ... in other words, I can't make my characters speak with the voice of Sean Connery.

Worth the price? Maybe. If you plan to do a lot of animation, it beats keyframing the lipsync by hand. But you can get Mimic 2 for $60 less (or even cheaper if you're a DAZ Platinum Clubber), and text-to-speech apps can be downloaded for free from the 'Net.
