CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application claims priority under the laws and rules of the United States, including 35 USC § 120, to the following patent application. The present application is a divisional application of U.S. application Ser. No. 11/688,748 filed Mar. 20, 2007, the contents of which are hereby incorporated by reference in its entirety. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to telecommunications in general, and, more particularly, to new features of telecommunications systems. 
     BACKGROUND OF THE INVENTION 
     Conference calls are a mainstay of modern business life, and, therefore, the need exists for inventions that improve the quality and usability of conference calls. 
     SUMMARY OF THE INVENTION 
     One of the principal disadvantages of conference calls in the prior art is that they often waste the participants&#39; time. For example, a conference call can comprise long intervals that are not relevant to many of the participants, which leads many participants mute their microphone and attend to other tasks. To the extent that those intervals are not relevant, this is a good thing because, as a practical matter, those people can use the time for more profitable work. 
     The problem is, of course, that when a participant&#39;s active participation becomes necessary, he or she has been pre-occupied and have not been paying attention. This is especially true when the timing of the participation is unpredictable or unexpected. Some embodiments of the present invention seek to address this problem. 
     In accordance with some embodiments of the present invention, a participant to a conference call can program the embodiment to listen for one or more “keywords” in the conference call. The keywords might be a participant&#39;s name or words associated with his or her area of knowledge. The embodiments of the present invention use speech recognition technology to listen for those words. When the embodiments detects that those words have been spoken, the embodiment alerts the participant—using audible, visual, and/or tactile signals—that the participant&#39;s attention to the call is warranted. When the keywords are chosen wisely, the benefit of the present invention can be great. 
     Some embodiments of the present invention comprise: establishing a call comprising a first telecommunications terminal, a second telecommunications terminal, and a third telecommunications terminal; receiving a first directive signal to transmit a first alert signal to the second telecommunications terminal when a first keyword is spoken in the call; detecting that the first keyword is spoken in the call; and transmitting the first alert signal to the second telecommunications signal because the first keyword has been spoken in the call.
