Special session: acoustic analysis of Parkinsonian speech: issues, methods, and applications

چکیده
Parkinson's disease (PD) is a slowly progressive and highly debilitating disease of the central nervous system, affecting 8,000,000 or more people the world over. By the time the disease is diagnosed, 60% of nerve cells in the substantia nigra are degenerated and 80% of dopamine is depleted in the striatum. There is an urgent need for cost-effective methods to detect the disease in its early phases, to differentiate it from other diseases, and to monitor its progression and its response to treatment. Parkinsonian speech is characterized by abnormally low voice intensity, with vocal decay, poor voice quality, reduced prosodic pitch and loudness inflection, imprecise vowels and consonants, dysrhythmia and short rushes of speech, mumbling, and reduced speech intelligibility

متن کاملبررسی ویژگیهای آکوستیکی مربوط به کنترل حرکتی گفتار در کودکان لکنتی و غیرلکنتی
Objective Stuttering is a developmental disorder of speech fluency with unknown causes. One of the proposed theories in this field is deficits in speech motor control that is associated with damaged control, timing, and coordination of the speech muscles. Fundamental frequency, fundamental frequency range, intensity, intensity range, and voice onset time are the most important acoustic componen...
