This report describes the activities performed and the |
|
progress made in the development of HARC (Hear And |
|
Respond to Continuous speech), BBN's spoken language |
|
system, from May 1, 1989 to February 29, 1992. |
|
Significant progress has been made both in terms of speed |
|
of understanding and accuracy of understanding. New |
|
search algorithms BBN developed during this period |
|
increased the speed of HARC by more than three orders of |
|
magnitude. The result has been the first spoken language |
|
system that runs in real-time on an off-the-shelf |
|
workstation, with no additional hardware. Furthermore, |
|
real-time performance was achieved without losing |
|
understanding accuracy. In tests performed by the |
|
National Institute of Standards and Technology (NIST) on |
|
data collected from the DARPA airline Travel Information |
|
System (ATIS) domain, the BBN HARC system had the best |
|
speech recognition and speech understanding performance. |
|
Another important milestone in this project has been the |
|
demonstration of HARC in a military logistical |
|
transportation planning application. |
