And a really sweet review in today's PC World:
For those who are brave enough to turn the computer over to a small child, DonationCoder founder Mouser's new Little Voice Commander (free/donationware) could be a good program to start with.
Little Voice Commander helps teach kids vocabulary and pronunciation on your PC.Little Voice Commander shows photos to reflect what your toddler's approximation of English says.This simple program encourages toddlers to speak and experiment by showing pictures of words they are likely to know, such as "dog," "apple," or, well, "baby," whenever a word is spoken or when a key on the keyboard is pressed. A sound file also speaks the word out loud. Press K, see a kite, hear "kite." The pictures typically arrange themselves into a mosaic; sometimes these images are repeated. The translation of babyspeak into American standard English depends on Microsoft's speech-recognition engine, making it necessarily an inexact business, but that's part of the fun. For example, imagine a child saying "No!" and being rewarded with pictures of snow.
