Text to Speech (text to audio)

There are plenty of applications and services that will convert text to audio for you .. but are they any good?

The free ones all come with basic computer voices.

VozMe allows you to embed a widget on the page, but you'll still need to copy / paste your text into the box. (And then it sounds like the computer is reading to you. Not recommended for bed-time stories, and also not for people with language backgrounds other-than-English.)
