This paper deals with speech enhancement in hands-free telecommunication systems. We summarize and discuss recent results on methods combining the two major problems encountered in such systems - acoustic echo cancellation and noise reduction -. Single microphone and two-microphone approaches are addressed. Finally, we outline the limitations of the different techniques and propose some prospects.
