Automatic Processing and Automatic Social Behavior01:28

Automatic Processing and Automatic Social Behavior

220
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...

Area of Science:

  • Speech acoustics and signal processing
  • Medical diagnostics and audiology
  • Computational linguistics

Background:

  • Velopharyngeal incompetence leads to hypernasality, reducing speech intelligibility in cleft palate patients.
  • Accurate hypernasality grading is crucial for clinical diagnosis by speech-language pathologists (SLPs).
  • Traditional Linear Prediction (LP) analysis has limitations in modeling vocal tract characteristics for hypernasality assessment.

Purpose of the Study:

  • To develop and evaluate advanced methods for classifying hypernasality grades.
  • To compare the efficacy of Stabilized Weighted Linear Prediction (SWLP) and Extended Weighted Linear Prediction (XLP) against traditional LP analysis.
  • To improve the accuracy of automated hypernasality assessment for clinical applications.

Main Methods:

  • Speech recordings from 60 cleft palate subjects and 20 controls (4640 Mandarin syllables) were analyzed.
  • Support Vector Machine (SVM) was utilized for classifying speech into four hypernasality grades.
  • Vocal tract characteristics were modeled using LP, SWLP, and XLP methods, focusing on spectral envelope analysis.

Main Results:

  • SWLP and XLP methods demonstrated lower correlation coefficients between normal and hypernasal speech compared to LP.
  • The spectral envelope of normal speech shows a faster decrease in the high-frequency region than hypernasal speech.
  • Classification accuracies for the four hypernasality grades ranged from 83.86% to 97.47% using SWLP and XLP.

Conclusions:

  • SWLP and XLP methods offer superior performance in distinguishing hypernasal from normal speech over traditional LP.
  • These advanced methods provide a more robust and accurate tool for assessing hypernasality grades.
  • The findings support the clinical utility of SWLP and XLP for assisted diagnosis in speech-language pathology.
