Abstract

A method and system is disclosed for accessing a remote personalized secretarial platform that permits a wide variety of functions with high flexibility, while being easily usable by an individual telephone subscriber. The platform can be accessed whenever the subscriber telephone is off-hook through a voice recognition monitor that monitors the subscriber line and is responsive to a preselected utterance to generate an access signal. Placed at the telephone switch facility, a monitor module is speech responsive individually to a plurality of lines that are off hook to generate signals that effect switch functions including bridging to the platform and modifying a subscriber switch feature profile.

Claims

1. In a public switched telephone network comprising a plurality of subscriber telephone lines, each coupled to an associated telephone switching facility, the improvement comprising:

a processor coupled to said network;

a voice recognition monitor coupled to one of said subscriber telephone lines for signaling to the telephone switching facility in response to recognition of a predetermined utterance whenever said one subscriber line is in an off-hook state;

bridging means in said telephone switching facility for bridging said one subscriber line to said processor in response to receipt of signals from said voice recognition monitor.

3. A network as recited in claim 1, wherein said voice recognition monitor is connected to a main distribution frame at said switching facility and is adapted to monitor a plurality of said lines.

4. A network as recited in claim 1, wherein said processor comprises a platform having storage means associated with a plurality of subscriber lines.

5. A network as recited in claim 4, wherein said processor includes scheduling means for maintaining a calendar of events.

6. A network as recited in claim 1, wherein said processor includes dial out means for initiating a switching facility to connect said one subscriber line to a remote subscriber line.

7. A network as recited in claim 1, wherein said processor comprises 3-way call set-up means.

8. A network as recited in claim 4, wherein said processor comprises voice interactive response means.

9. A network as recited in claim 8, wherein said processor includes message storage means for storing messages associated with respective subscribers in any of a plurality of formats.

10. A network as recited in claim 8, wherein said processor comprises text to speech conversion means.

11. A network as recited in claim 3, wherein said switching facility comprises an administrative module and said voice recognition monitor includes a processor coupled by a data link to said administrative module.

12. A network as recited in claim 11, wherein said processor included in said voice recognition monitor is responsive to recognition of speech on said one subscriber line to modify a subscriber profile stored at said switching facility prior to said one subscriber line attaining an on-hook state.

2. In a public switched telephone network comprising a plurality of subscriber telephone lines, each coupled to an associated telephone switching facility, the improvement comprising:

a processor coupled to said network;

a voice recognition monitor coupled to one of said subscriber telephone lines for signaling to the telephone switching facility in response to recognition of a predetermined utterance when said one subscriber line is in an off-hook state;

bridging means in said telephone switching facility for bridging said one subscriber line to said processor in response to receipt of signals from said voice recognition monitor;

wherein said voice recognition monitor is coupled to said one line between subscriber location and telephone switching facility and is connected to said switching facility by a data link for transmitting data signals from said monitor to said switching facility.

13. In a public switched telephone network comprising a plurality of subscriber telephone lines, each coupled to an associated telephone switching facility, the improvement comprising:

a processor coupled to said network;

a voice recognition monitor coupled to one of said subscriber telephone lines for signaling to the telephone switching facility in response to recognition of a predetermined utterance whenever said one subscriber line is in an off-hook state;

means responsive to receipt of signals from said voice recognition monitor for changing a subscriber profile table associated with said one subscriber line that is temporarily stored in said switching facility during an existing phone call.

14. A network as recited in claim 13, wherein said profile table comprises a compilation of switch features available for respective subscriber lines and said table is changed by the addition of at least one new switch feature.

15. A network as recited in claim 14, wherein said one new switch feature is a conference call feature.

16. In a public switched telephone network comprising a plurality of subscriber telephone lines, each coupled to an associated telephone office switch, a method for accessing a personal secretary service platform, comprising the steps of:

monitoring a subscriber line whenever it is in an off-hook state for a predetermined utterance by a user of a telephone connected to said subscriber line;

detecting said predetermined utterance;

in response to said step of detecting, generating a wake-up signal for accessing the personal secretary service platform; and

applying said wake-up signal to said switch to activate a switch function while said subscriber line remains in the off-hook state.

17. A method as recited in claim 16, wherein said switch function comprises bridging said subscriber line with a personal secretary platform.

18. A method as recited in claim 16, wherein said switch function comprises establishing a three way conference call.

19. A method as recited in claim 16, wherein said switch function comprises changing a line translation table that is stored in said switch.

20. A method as recited in claim 19, wherein said translation table is changed to add a conference call feature.

21. A method as recited in claim 16, wherein said step of generating is responsive to speech originating only at said subscriber line.

22. A method as recited in claim 16, further comprising authenticating a caller from a line remote from said subscriber line and wherein said step of generating is responsive to speech originating from said remote line only after occurrence of said authenticating step.

23. In a public switched telephone network including a central office switching system, a subscriber telephone line connected to said central office switching system, a voice recognition monitor associated with said subscriber telephone line, and a secretary service platform associated with said central office switching system, a method comprising the steps of:

monitoring said subscriber telephone line for predetermined utterances at all times that said subscriber telephone line is in an off-hook state;

detecting one of said predetermined utterances;

generating an activation signal in response to said detecting step; and

establishing a telephone connection between said secretary service platform and said subscriber telephone line in response to said activation signal.

24. The method of claim 23, wherein the monitoring step includes:

monitoring said subscriber telephone line for said predetermined utterances during the presence of a dial tone.

25. The method of claim 23, wherein the monitoring step includes:

monitoring an ongoing call on said subscriber telephone line for said predetermined utterances.

26. The method of claim 23, including at least one of following steps:

maintaining a calendar;

receiving messages;

arranging calls to one or more parties.

27. The method of claim 23, including the step of:

changing a programmed switch feature after a call has been connected to a dialed destination.

28. A public switched telephone network comprising:

a central office switching means;

a multiservice platform means for performing personal secretary functions;

means for monitoring a subscriber telephone line for predetermined utterances whenever said subscriber telephone line is in an off-hook state, said monitoring means including;
