Radiologist David Weiss, M.D., has an inexpensive alternative to a white noise generator to use in conjunction with speech recognition software.

By obliterating background sounds, the white noise generators make it easier for the software to recognize and translate speech. "A door closing can be a disaster" for the software, Weiss noted during his talk at RSNA 2010 in Chicago. But rather than a generator, the radiologist turns on a fan when he dictates.

Weiss also demonstrated how embedding macros into his software speeds up dictation. For commonly dictated phrases, Weiss uses the tool to pop in an entire phrase by uttering just one or two words. He said that current speech recognition software is highly accurate, describing how the software "learns" the voice patterns of the dictating physician.
