Abstract
A telephony application such as an interactive voice response (“IVR”) needs to identify quickly the nature of the call (e.g., whether it is a person or machine answering a call) in order to initiate an appropriate voice application. Conventionally, the call stream is sent to a call-progress analyzer (“CPA”) for analysis. Once a result is reached, the call stream is redirected to a call processing unit running the IVR according to the analyzed result. The present scheme feeds the call stream simultaneous to both the CPA and the IVR. The CPA is allowed to continue analyzing and outputting a series of analysis results until a predetermined result appears. In the meantime, the IVR can dynamically adapt itself to the latest analysis results and interact with the call with a minimum of delay.
