In this paper, the feasibility of a system developed for the remote diagnosis of voice pathologies is analysed. More specifically, the performance of MFCC-based pathology detectors over speech transmitted through an analogue telephone channel is studied. Results indicate that MFCC are voice features fairly robust to amplitude distortion and almost insensitive to phase distortion, but the efficiency of a voice pathology detector based on these features is clearly decreased when the speech samples are transmitted through a telephone channel.
