SUMMARY:
     This paper presents a continuous speech recognition system for mobile touch screen devices.  Participants had a word entry rate of 18 words per minute while seated and 13 words per minute while walking around.  In the past speech recognition methods have suffered from poor accuracy.  This paper uses Parakeet which is a touch screen system for recognizing continuous speech.  Parakeet was the first system to test voice recognition while walking around.

DISCUSSION:
     In my mind this system fails to prove it is accurate enough for people to actually use.  It mentions that when the intended sentence was in the confusion network it was able to find and select the correct sentence 96% of the time.  Future work would have to be done to improve performance with sentences that are not in the confusion network.
