abstract: This work evaluates the capabilities of the Glottal to Noise  Excitation Ratio for the screening of voice disorders. A lot of  effort has been made using this parameter to evaluate voice  quality, but there do not exist studies that evaluate the  discrimination capabilities of this acoustic parameter to classify  between normal and pathological voices. A set of 226 speakers  (53 normal and 173 pathological) taken from a voice disorders  database were used to evaluate the usefulness of this parameter  for discriminating normal and pathological voices. In order to  evaluate this parameter, the effect of the bandwidth of the  Hilbert envelopes and the frequency shift have been analyzed,  concluding that a good discrimination is obtained with a  bandwidth of 1000 Hz and a frequency shift of 300 Hz. The  results confirm that the Glottal to Noise Excitation Ratio  provides reliable measurements  in terms of discrimination  among normal and pathological voices, comparable to other  classical long-term noise measurements found in the literature,  such as Normalized Noise Energy or Harmonics to Noise Ratio,  so this parameter is a good candidate to be used for screening  purposes.
