Speech Recognition and Synthesis

Speech recognition is a truly amazing human capacity, especially when you consider that normal conversation requires the recognition of 10 to 15 phonemes per second. It should be of little surprise then that attempts to make machine (computer) recognition systems have proven difficult. Despite these problems, a variety of systems are becoming available that achieve some success, usually by addressing one or two particular aspects of speech recognition.

A variety of speech synthesis systems, on the other hand, have been available for some time now. Though limited in capabilities and generally lacking the ``natural'' quality of human speech, these systems are now a common component in our lives.
