Abstract

A communications system is designed to allow a call waiting subscriber who is already busy on a first call to receive information associated with a message being recorded by a second caller attempting to reach the subscriber. According to one aspect of the principles disclosed herein, a one-way conference call is established between the second caller and the subscriber as the message is being recorded to allow the subscriber to eavesdrop on the message. According to another aspect of the principles disclosed herein, an Automatic Speech Recognition system may transcribe the message being recorded into ASCII coded data that is delivered to the called party. The received message allows the subscriber to effectively assess whether the first call in progress should be interrupted to answer the second call in waiting.

Claims

1. A method implemented by a communications services provider for delivering information associated with an incoming call, the method comprising the steps of:

receiving an incoming call that is initiated by a caller and that is destined for a subscriber who is busy on a first call; and

in response to receiving a signal indicative of unavailability of said subscriber, recording a message generated by said caller for said subscriber;

converting speech input, associated with the message being recorded into text; and

transmitting said text to said subscriber, said text being transmitted contemporaneously with the recording of the message.

2. The method of claim 1 wherein said transmission is initiated after a call waiting signal has been delivered to the caller.

3. The method of claim 2 wherein said transmission is initiated in response to receiving a request from said subscriber to effectuate said transmission.

4. The method of claim 1 wherein said text is written in a language pre-selected by the subscriber.

7. The system of claim 1 wherein said transmission is established in response to receiving a request from said subscriber to effectuate said connection.

5. A method implemented by a communications services provider for delivering information associated with a call, the method comprising the steps of:

receiving an incoming call that is initiated by a caller and destined for a subscriber who is busy on a first call;

in response to receiving a signal indicative of unavailability of said subscriber, establishing a communications path between said caller and a messaging system which delivers a greeting announcement to said caller via said path to invite said caller to leave a message for said subscriber;

converting speech input, associated with the message into text;

establishing a one-way connection from said caller to said called party for the transmission of the text; and

tearing down said communications path.

6. A system for delivering to a called party information associated with a call, the system comprising:

a communications switch which receives an incoming call initiated by a caller and destined for a called party'"'"'s telephone set which is already in use for another call; and

a messaging system, including a speech recognition unit, for converting a message from said caller into text and transmits said text to said communications switch coupled thereto, said message being recorded for delivery to said called party contemporaneously with said text.
