DESCRIPTION:Correcting recognition errors is often necessary in a speech i
 nterface. These errors not only reduce users' overall entry rate\, but can
  also lead to frustration. While making fewer recognition errors is undoub
 tedly helpful\, facilities for supporting user-guided correction are also 
 critical. \n\nWe explore how to better support user corrections using Para
 keet – a continuous speech recognition system for mobile touch-screen de
 vices. Parakeet's interface is designed for easy error correction on a han
 dheld device. Users correct errors by selecting alternative words from a w
 ord confusion network and by typing on a predictive software keyboard. Our
  interface design was guided by computational experiments and used a varie
 ty of information sources to aid the correction process. In user studies\,
  participants were able to write text effectively despite sometimes high i
 nitial recognition error rates. Using Parakeet as an example\, we discuss 
 principles we think are important for building effective speech correction
  interfaces.\n\nThis will be a short 15-minute talk.  \n\nA copy of the pa
 per as well as a video are available "here":http://www.keithv.com/pub/huma
