Abstract

A telephone answering device with an amplication feature during outgoing message has a blank portion for a couple of seconds between first outgoing message and second outgoing message. If a calling party speaks his name during the blank portion, his voice is amplified in the region of the device to be answered by any people around it. If the calling party does not speak his name, however, a second outgoing message will be produced after the blank portion. After a beep tone, the calling party can leave his message on the incoming message tape.

Claims

1. A telephone answering device which makes a loop circuit to establish communication between calling and called parties on a telephone line upon reception of a calling signal and sends on the line an outgoing message prerecorded on a recording medium, comprising:

switching means having a first state responsive to an incoming calling signal for controlling said device to reproduce from the recording medium a first pre-recorded outgoing message to a caller and immediately thereafter to establish on the recording medium a silent portion of a predetermined duration of time wherein any pre-recorded message is not reproduced, and a second state responsive to the end of said predetermined duration of time for controlling said device to reproduce from the recording medium a second prerecorded outgoing messaage;

means for amplifying the voice spoken by the calling party during said silent portion;

loudspeaker means for audibly reproducing the voice amplified by said amplifying means so that the called party will hear the voice without taking a telephone off-hook;

means for generating a low frequency signal;

means for blocking the low frequency signal from the telephone line;

means for recording on the recording medium the low-frequency signal before and after the silent portion;

means for detecting said low frequency signal to control said amplifying means to amplify outgoing messages during only the silent portion during play back; and

means for turning off said amplifying means just before said second outgoing message is reproduced so that said second outgoing message is not reproduced by said loudspeaker means.

2. A method of operating a telephone answering device which makes a loop circuit to establish communication between calling and called parties on a telephone line upon reception of a calling signal and sends on the line an outgoing message pre-recorded on a recording medium, comprising the steps of:

reproducing of the recording medium a first prerecorded outgoing message to a caller on the line and immediately thereafter establishing of the recording medium a silent portion of a predetermined duration of time wherein any prerecorded message is not reproduced, and at the end of said predetermined duration of time reproducing from the recording medium a second pre-recorded outgoing message;

amplifying the voice spoken by the calling party during reproduction of said silent portion;

audibly reproducing the voice amplified by said amplifying means so that the called party will hear the voice of the calling party without taking a telephone off-hook;

generating a low frequency signal;

blocking the low frequency signal from the telephone line;

recording on the recording medium the low-frequency signal before and after the silent portion;

detecting said low frequency signals to control amplification of outgoing messages during only the silent portion during play back; and

disabling amplification of the voice of the calling party just before said second outgoing message is reproduced so that said voice is not heard by the called party.
