Intelligent recognition of speech signals using caller demographics
First Claim
1. In a switching system for connecting a calling station to a called station a method of establishing completion of said connection comprising the steps of:
- responsive to said calling station dialing a destination identifier, establishing the identity of said calling station and using said identity to address a data base;
deriving from said data-base information relating to demographics of said calling station;
selecting from a plurality of speech recognition resources a first resource indicated by said demographic information;
establishing connection to said off-hook station;
inputting a spoken command from a caller at said calling station to said selected resource;
outputting from said first speech recognition resource a first output signal responsive to said spoken command;
selecting from said plurality of speech recognition resources a second resource responsive to said first output signal;
outputting from said second speech recognition resource a second output signal;
inputting a second spoken command from said caller at said calling station to said second resource;
outputting from said second speech recognition resource a third output signal responsive to the second spoken command;
determining the degree of traffic through said plurality of speech recognition resources;
comparing the determined degree of traffic to a predetermined traffic load; and
responsive to said determined degree of traffic being below said predetermined load, inputting at least one of said spoken commands to a plurality of said resources in parallel.

Abstract
In a switching system for connecting a call between a calling station and a called station, a system and method of voice recognition using a concentrated or distributed multiplicity of voice recognition and other resources with a facility for selecting an initial resource on the calling station going off-hook by accessing a demographic database using common channel signaling and selecting a prompt to be delivered to the caller from a multiplicity of preselected prompts and reacting to a response by the caller with further addressing of database information to continue to select from said multiplicity of resources the most appropriate resource or resources in reaction to caller utterances. According to another feature the selection of resources is aided by optical means at the calling station delivering information regarding characteristics of the caller including lip movement to permit lip reading.

16. In a Publicly Switched Telephone Network (PSTN) which includes Common Channel Signaling (CCS) and a Signal Control Point (SCP), a method of completing a call from a calling station to a called station comprising the steps of:
-
responsive to said calling station dialing a destination identifier, establishing the identity of said calling station through said CCS pursuant to the conventional functioning of said PSTN; using said identity of said calling station to address a data base associated with said SCP; deriving from said data base information relating to demographics of said calling station; selecting from a plurality of resources a resource indicated by said demographic information; establishing a connection to said off-hook station; inputting a spoken command from a caller at said calling station to said selected resource; sensing from said calling station characteristics of said caller through means other than audio sensing means and generating a signal representative thereof; outputting to said caller an audio signal selected from a plurality of preestablished audio signals based on at least one of (a) audio sensing of said spoken command and (b) sensing other than audio; inputting a second spoken command from said caller responsive to said audio signal outputted to said caller; outputting from said plurality of resources a second output signal responsive to said second spoken command; determining the degree of traffic through said plurality of resources; comparing the determined degree of traffic to a predetermined traffic load; and responsive to said determined degree of traffic being below said predetermined load, inputting at least one of said spoken commands to a plurality of said resources in parallel. - View Dependent Claims (17)

18. A switching system including interconnected switching offices and stations connected to at least certain of said switching offices and a Common Channel Signaling System (CCSS) for controlling the connection of a calling station to a called station through said switching system;
-
a plurality of speech recognition resources connected to said switching system; a data base associated with said CCSS having stored therein demographic information related to said stations connected to said switching stations; means for addressing said data base in response to said calling station dialing a destination identifier to access demographic information relating to said dialing station; means responsive to said accessed information to select at least one of said resources and to connect a signal from said calling station to said selected resource; means associated with said plurality of resources for outputting a signal responsive to a spoken command to said calling station; and audio response means for generating a plurality of predetermined audio responses, said audio response means generating an audio response responsive to said signal responsive to said spoken command; said audio response inviting a further spoken command from said calling station, and including means associated with said plurality of resources for outputting a signal responsive to outputs from at least a pair of said resources operating in parallel. - View Dependent Claims (19, 20, 21)
