Abstract
One embodiment can provide a method and a system for detecting change points within a conversation. During operation, the system can obtain a signal associated with the conversation and extract a one-dimensional (1D) feature function from the signal. The system can apply Gaussian smoothing on the 1D feature function, identify zero-crossing points on the smoothed 1D feature function, and determine a set of change points within the conversation based on the identified zero-crossing points.
