摘要

Communication is a bridge between people which enables them to share facts, ideas, feelings etc. with each other. Speech communication is easier and simpler compared to other types of communication. But speech disorders affect one's ability to communicate. Dysarthria is a neuro-motor disorder, where one losses his/her ability to articulate words normally due to tongue/muscle weakness or stroke etc. It results in distorted speech which is hard to understand. Dysarthria affect more on the articulation of consonants (stops in particular) than on the articulation of vowels. Intelligibility varies greatly depending on the extent of neurological damage. As consonants are important than vowels in measuring the intelligibility, distortions in consonant production of dysarthric speech are studied and modifications are performed. This work aims at correcting devoicing of voiced stop (voiced stops are pronounced as unvoiced stops with the same place of articulation) by detecting important time instants such as glottal onset, glottal offset and burst onset thereby modifying the distortions in dysarthric speech using TMS320C6713 DSK with CC Studio 5.5. After the dysarthric speech has been recorded on the DSK 6713 processor modification is done to improve its intelligibility. Two databases were used in the experiment such as Universal Access (UA) database and Torgo database. Out of 65 bursts expected from UA database and 128 bursts expected from Torgo database, 84.6% and 82.81% bursts were detected correctly within 0.3 s intervals respectively.
