Too many compare Kindle’s text-to-speech to a beautifully crafted and performed audio book. That is a mistake. There’s too much additional information in an audio book represented by among other things, the voices of famous actors. It’s hard to imagine a text-to-speech engine ever being able to impart the drama and emotion of a Richard Burton or Peter O’Toole. Not to mention the fact that two audio books performed by different actors will result in two different works.
The text-to-speech capability in Kindle is obviously not on par with an audio book, or up to speed with the best speech engines. However, once you’re into a book and familiar with the characters and story line, brief episodes with Kindle’s text-to-speech are perfectly acceptable.
For example, let’s say you started reading a particularly thrilling book last evening and continued reading the next morning. Sadly, you must leave for work. Instead of listening to the radio or another rap song, fire up your Kindle and "read" while you drive. Again, it’s not great audio, but at this point you’re so engrossed in the story it doesn’t matter.
Try it. You might be surprised.
