Detection of characteristics of human-machine interactions for dialog customization and analysis
First Claim
1. A method comprising:
- establishing a speech-based dialog between a person and a machine during a call, wherein the person uses a communication device to speak to the machine via a communication channel during the call;
automatically detecting a characteristic during the dialog in real time, wherein the characteristic is a characteristic of the person, the communication device, the communication channel, or an environment in which the person is located during the dialog, but the characteristic does not uniquely identify the person, the communication device, or any user account; and
selecting a destination to which the call should be routed, based on the detected characteristic, and not based on the meaning of any speech or the failure to recognize any speech during the dialog.

Abstract
A system which uses automatic speech recognition to provide dialogs with human speakers automatically detects one or more characteristics, which may be characteristics of a speaker, his speech, his environment, or the speech channel used to communicate with the speaker. The characteristic may be detected either during the dialog or at a later time based on stored data representing the dialog. If the characteristic is detected during the dialog, the dialog can be customized for the speaker at an application level, based on the detected characteristic. The customization may include customization of operations and features such as call routing, error recovery, call flow, content selection, system prompts, or system persona. Data indicative of detected characteristics can be stored and accumulated for many speakers and/or dialogs and analyzed offline to generate a demographic or other type of analysis of the speakers or dialogs with respect to one or more detected characteristics.

18. A system comprising:
-
a front end to generate a set of features in response to speech from a person during a dialog with the person, wherein the person uses a communication device during a call communicate with the system via a communication channel; a set of models; a speech recognition engine to recognize the speech from the person based on the features and the models; a characteristic detector to detect a characteristic of the person, the communication device, the communication channel, or an environment in which the person is located during the dialog, wherein the characteristic does not uniquely identify the person, the communication device, or any user account; and a call routing unit to select a destination to which the call from the person should be routed, based on the detected characteristic, and not based on the meaning of any speech or the failure to recognize any speech during the dialog. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method comprising:
-
establishing a speech-based dialog between a person and a machine, wherein the person uses a communication device to communicate with the machine via a communication channel during the dialog; automatically detecting a characteristic during the dialog in real time, wherein the characteristic is a characteristic of the person, the communication device, the communication channel, or an environment in which the peson is located during the dialog, and wherein the characteristic does not uniquely identify the person, the communication device, or any user account; and dynamically customizing a call flow of the dialog for the person during the dialog, based on the detected characteristic, and not based on the meaning of any speech or the failure to recognize any speech during the dialog. - View Dependent Claims (34, 35, 36, 37, 38)
