■題目
Pathological speech synthesis and evaluation

■概要
Pathological speech synthesis and evaluation is an emerging field within speech technology that focuses on the creation and analysis of speech signals affected by various disorders. This technology aims to develop tools and systems that can accurately replicate and analyse pathological speech patterns, providing significant benefits in fields such as speech therapy, assistive communication with automatic speech recognition.
The lecture will cover terminologies that are required to understand pathological speech and disorders, and introduce the basic principles of the currently used state-of-the-art technologies for pathological speech synthesis and evaluation. We will discuss challenges, such as, evaluation the effectiveness and naturalness of synthesized pathological speech. This challenge remains a significant hurdle, as traditional evaluation metrics may not be suitable for assessing pathological speech. This necessitates the development of new evaluation frameworks that can account for the unique characteristics of disordered speech.
