System and method for analyzing and classifying calls without transcription
First Claim
1. A method in a computing system for analyzing a telephone call without transcription, the method comprising:
- receiving an audio signal of the telephone call, wherein the telephone call includes a first channel and a second channel; and
generating a display based on the received audio signal, the display comprising;
a first portion illustrating the first channel, wherein the illustration of the first channel depicts a first time-in-activity of the telephone call, the depiction of the first time-in-activity of the telephone call including an identification of speech activity and non-speech activity, the speech activity and non-speech activity being depicted as a function of time;
a second portion illustrating the second channel, wherein the illustration of the second channel depicts a second time-in-activity of the telephone call, the depiction of the second time-in-activity of the telephone call including an identification of speech activity and non-speech activity, the speech activity and non-speech activity being depicted as a function of time; and
a third portion indicating an outcome of the telephone call, wherein the outcome is identified by analyzing a pattern of interaction between the first time-in-activity of the telephone call and the second time-in-activity of the telephone call.

Abstract
A facility and method for analyzing and classifying calls without transcription. The facility analyzes individual frames of an audio to identify speech and measure the amount of time spent in speech for each channel (e.g., caller channel, agent channel). Additional telephony metrics such as R-factor or MOS score and other metadata may be factored in as audio analysis inputs. The facility then analyzes the frames together as a whole and formulates a clustered-frame representation of a conversation to further identify dialog patterns and characterize call classification. Based on the data in the clustered-frame representation, the facility is able to make estimations of call classification. The correlation of dialog patterns to call classification may be utilized to develop targeted solutions for call classification issues, target certain advertising channels over others, evaluate advertising placements at scale, score callers, and to identify spammers.
