Abstract
Abstract A method for dialing a telephone, using voice recognition to initiate the dialing and to determine the correct telephone number. The dialing is initiated with a spoken dial command (24) that is recognized by using speaker independent templates (25) that are stored locally with respect to the caller's telephone. The correct telephone number is recognized by using speaker dependent templates (29) that are downloaded from a central database or by using speaker independent templates (31) stored locally.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
120 words
A method of using voice recognition computer processing to direct a caller's telephone call to a called destination, comprising the steps of: identifying the caller; accessing a database containing speaker dependent speech recognition templates; downloading said speaker dependent templates from a central database to a local station in communication with said caller's telephone; detecting a dial command spoken by said caller; accessing a database containing speaker independent speech recognition templates; comparing said dial command to said speaker independent templates; detecting a destination identifier spoken by said caller; accessing a database containing speaker dependent speech recognition templates associated with said caller; comparing said destination identifier to said speaker dependent templates; and dialing an appropriate number in response to said comparing steps.
Claim 2
Dependent Claim
27 words
The method of Claim 1, wherein said step of accessing a database containing speaker dependent speech recognition templates further comprises downloading said templates to said local station.
Claim 3
Dependent Claim
32 words
The method of Claim 1, and further comprising the steps of comparing said destination identifier to a set of speaker independent templates and comparing said destination identifier to said speaker independent templates.
Claim 4
Dependent Claim
22 words
The method of Claim 1, wherein said steps of comparing said destination identifier to speaker dependent and speaker independent templates occur simultaneously.
Claim 5
Dependent Claim
29 words
The method of Claim 1, wherein said step of identifying said caller is performed using identification numbers and speaker independent templates representing said numbers stored at said local station.
Claim 6
Dependent Claim
25 words
The method of Claim 1, wherein said step of identifying said caller is performed by detecting the caller's spoken name and using speaker dependent templates.
Claim 7
Dependent Claim
21 words
The method of Claim 1, and further comprising the step of providing the caller with a set of permissible dial commands.
Claim 8
Dependent Claim
19 words
The method of Claim 1, wherein said comparing steps are performed using dedicated signal processors of said local station.
Claim 9
Dependent Claim
43 words
The method of Claim 1, wherein said steps of identifying said caller, accessing said speaker dependent templates, and downloading said speaker dependent templates, occur simultaneously with said steps of detecting said dial command, accessing said speaker independent templates, and matching said dial command.
Claim 10
Dependent Claim
96 words
A voice recognition system for dialing a telephone, comprising: a number of local database memories that store speaker independent voice recognition templates; a central database memory that stores sets of speaker dependent templates, each set associated with a caller, wherein each template represents a destination identifier; a local processing system programmed for identifying said caller, for recognizing said dial command using said speaker independent templates, for requesting a set of speaker dependent templates associated with said caller to be downloaded from said central database memory, and for recognizing a destination identifier using said speaker dependent templates.
Claim 11
Dependent Claim
23 words
The system of Claim 10 and further comprising a communications system for downloading said set of speaker dependent templates to said local database.
Claim 12
Dependent Claim
30 words
The system of Claim 10, wherein said local processing system comprises a host processing system for handling said downloading task and a signal processing system for handling said recognition tasks.
Claim 13
Dependent Claim
20 words
The system of Claim 10, wherein said local database memories further store speaker independent templates for recognizing said destination identifier.
Claim 14
Dependent Claim
26 words
The system of Claim 10, wherein said local processing system is programmed for recognizing said destination identifier by using speaker independent and speaker dependent templates simultaneously.
Claim 15
Dependent Claim
27 words
The system of Claim 10, wherein said host processing system is programmed to download said speaker dependent templates while said signal processing system matches said dial command.
