摘要：
Automatically calibrating echo canceller software has been developed for voice over Internet protocol (VoIP) applications on smartphones. Because the audio properties of smartphones typically depend on the model, the speech quality of a VoIP application may sometimes degrade, especially during hands-free conversations. We extended the calibration ability of our software in order to handle the variations in smartphone audio properties. As a result, our software exhibited better performance than most conventional software.
