Call classifier using automatic speech recognition to separately process speech and tones
First Claim
Patent Images
1. A method for doing call classification on a call to a destination endpoint, comprising the steps of:
- receiving audio information from the destination endpoint;
analyzing using automatic speech recognition the received audio information for a first type of classification;
analyzing using automatic speech recognition the received audio information for a second type of classification; and
determining a call classification for the destination endpoint in response to the analysis of the first type of classification and the analysis of the second type of classification.
