Title

Modifying Dysarthric Vowels using Formant Transformation Technique and Vowels Synthesis

Abstract

Speech is the most preferred way of communication. However, people with communication disorders find it difficult to communicate fluently. Dysarthria is one such disorder where person lacks control over the muscles and articulators. These people may not be able to utter some of the phonemes properly. This decreases speech intelligibility. This paper is based on formants transformation for dysarthric vowels, with the goal of improving intelligibility. Formants are extracted using PRATT software and these formants are modified to more closely approximate the desired targets using transformation function. In order to improve a level of understanding, the modification of formants of dysarthric speaker vowel portion with the known vowel portion formants of normal speaker. After all modifications, the synthesized vowels are far better than dysarthric speaker vowels. Objective evaluation is carried out, and results show that the transformed formants are approximately close to normal speech.

Key Words

Dysarthria, Intelligibility, Improper articulation, Formant transformation, Synthesized speech
