In this paper a continuous digit recognizer over the telephone network in real time will be de- scribed. The activity has allowed the realization of a system, installed in some Italian telephone exchanges, for providing semi-automatic collect call services. Data collection has also been per- formed, and a field database was built. Either a continuous digit recognition task and a confirmation task, requiring rejection, have been defined. Recognition results are presented.
