Pathological Speech Processing: State-of-the-Art, Current Challenges, and Future Directions Conference Paper uri icon

abstract

  • © 2016 IEEE. The study of speech pathology involves evaluation and treatment of speech production related disorders affecting phonation, fluency, intonation and aeromechanical components of respiration. Recently, speech pathology has garnered special interest amongst machine learning and signal processing (ML-SP) scientists. This growth in interest is led by advances in novel data collection technology, data science, speech processing and computational modeling. These in turn have enabled scientists in better understanding both the causes and effects of pathological speech conditions. In this paper, we review the application of machine learning and signal processing techniques to speech pathology and specifically focus on three different aspects. First, we list challenges such as controlling subjectivity in pathological speech assessments and patient variability in the application of ML-SP tools to the domain. Second, we discuss feature design methods and machine learning algorithms using a combination of domain knowledge and data driven methods. Finally, we present some case studies related to analysis of pathological speech and discuss their design.
