Try a System

If you’d like to have a chance to try out an application that uses CMU Sphinx, try the Communicator, an experimental system that helps you plan air travel. You can reach it at the toll-free number 1-877-CMU-PLAN (1-877-268-7526) or at +1 412 268 1084.. The system will provide real flight information. The system may be sensitive to loud background noises, especially over cell phones.
