Telephone network speech signal enhancement.

摘要

The quality of voice signals transmitted by a telephone station set (S1), or similar device, are enhanced before such signals are delivered to a receiving telephone station set (S2) by restoring the level of speech energy attenuated by the transmitting set, in which such restoration is performed at a point along a telephone connection between the transmitting and receiving telephone stations, for example, at a point within a telecommunications system (100) which establishes the connection. <IMAGE>
