Unsupervised Rhythm and Voice Conversion to Improve ASR on Dysarthric Speech

Karl El Hajal, Enno Hermann, Sevada Hovsepyan +1

Automatic speech recognition (ASR) systems struggle with dysarthric speech due to high inter-speaker variability and slow speaking rates. To address this, we explore dysarthric-to-…
