DEFINITION

Classification: 379/67.1

AUDIO MESSAGE STORAGE, RETRIEVAL, OR SYNTHESIS:

(under the class definition) System, process, or instrument for the two-way electrical transmission of intelligible audio information further comprising structure for the retention, recovery, or formation of an audio message signal.

(1) Note. Such storage or retrieval must include a telephone system component at least nominally claimed. Mere designation of the apparatus as a "telephone answering device" is, of itself, insufficient for classification in this or indented subclasses.
