"The improvements in the latest release of ViaVoice, Version 8, include better voice control over the Windows desktop and a shorter setup time (but reading the training scripts out loud still takes about three times as long as NatSpeak's five-minute blurb). NaturallySpeaking 5, for its part, has beefed-up features for e-mail and Web browsing."
"All but the most basic versions of these programs let you control the computer itself by speaking (opening menus and switching programs, for example). Versions of each program can transcribe recordings from certain pocket voice recorders. But NaturallySpeaking is more accurate than its rival, and its commands are more natural; to capitalize a word, for example, you just say 'cap before pronouncing it."
"The equivalent ViaVoice command is 'capitalize this,' which can tie your tongue into knots when you dictate, for example, 'How Green Was My Valley.' On the other hand, ViaVoice is the only dictation program available for Linux."
