| Abstract: | Speech is one of the common modes of
communication and it is a process of transferring
information from one entity to another. In recent years
there has been much research on unvoiced/voiced
classification and voice pathology classification. In
this research work a simple fuzzy classifier has been
designed to segment the voiced and unvoiced portions
of a speech signal. A simple feature extraction
algorithm is proposed to extract the Tri Mean relative
average perturbation (Tri Mean-RAP) features from
the segmented voice portion of the speech signal.
Further, the extracted Tri Mean-RAP features are used
to model the fuzzy pathology identification system. In
the proposed fuzzy classifier, the energy, change in
energy and difference in the change in energy level
between the adjacent frames are fuzzified and rules are
formulated to segment the voiced portion. The Tri
Mean-RAP features are then extracted from the
segmented voice portion, the Tri Mean-RAP features
are fuzzified and rules are formulated to identify the
voice pathology of the speech signal. The proposed
methods are validated through simulation. |
