Abstract
An automated telephone operator platform (e.g., an auto attendant) has a natural names library associated therewith. The natural names library comprises a large database of audio files representing common objects expected to be recognized by a telephone-based ASR application associated with or executing on the platform. Whenever the ASR application requires playback of an object file (e.g., a user's name associated with a mailbox), the system first determines whether the user has recorded a sample of his or her own voice. If so, the user's actual voice sample is output. If, however, the user's actual voice sample is not available or has not been recorded, the ASR application accesses the database to retreive objects files from which it then builds an appropriate output string.
