Speech recognition is the understanding of the spoken word by technology, and the implementation of various actions based on the understood words. There aren't very many speech recognition companies out there, and many of the the ones that do trade publicly are not generating positive earnings. Many of them are very low cap, and should therefore be considered very speculative.
Despite this problem, here are some that are some that just might be worth hearing about:
