Abstract :
In this paper some considerations for the realisation of a most natural handsfree speaking are presented. Its essential features comprise full duplex operation, speech loudness well adapted to the user´s environment, background noise suppression and cancellation of line echoes. Furthermore its algorithms be able to work properly even under severe weaknesses caused by low cost components to allow the realisation of economic products.
