ADAPTIVE SPEAKERPHONE SYSTEM |
摘要 |
A system and method for adjusting telephonic control signals transmitted from a central station to a remote station. The signals are automatically adjusted according to the response of the remote station. The signals are adjusted to control speakerphone operation at the remote station in such a way as to provide communication with minimum audible annoyance. The method is especially useful in a personal emergency response system in which the speakerphone is part of a subscriber station to achieve a greater voice range than a voice activated speakerphone system.
