ABSTRACT:
A computer scans the voice messages for phrases that will be detected as DTMF digits and creates a record of where, when and for how long the possible problem maybe occurring. This allows prerecorded or synthesized messages from a Voice Response Announcement System to be checked for error causing DTMF digits prior to being placed into operation. The complete system consists of a computer containing the detection unit, a disk storage unit and scanning program. The Detection unit is placed within the computer and connects the system to the Central Office Switching Network for access to the Voice Response Announcement System.
