More Information
Summary:Network communication speech handling systems are provided herein. In one example, a method of processing audio signals by a network communications handling node is provided. The method includes receiving an incoming excitation signal transferred by a sending endpoint, the incoming excitation signal spanning a first bandwidth portion of audio captured by the sending endpoint. The method also includes identifying a supplemental excitation signal spanning a second bandwidth portion that is generated at least in part based on parameters that accompany the incoming excitation signal, determining a normalized version of the supplemental excitation signal based at least on energy properties of the incoming excitation signal, and merging the incoming excitation signal and the normalized version of the supplemental excitation signal by at least synthesizing an output speech signal having a resultant bandwidth spanning the first bandwidth portion and the second bandwidth portion.
