Area of Science:

  • Linguistics
  • Speech Science
  • Biomedical Engineering

Background:

  • Ultrasound imaging is widely used in speech production research.
  • Standardization in quantifying and statistically analyzing ultrasound tongue data is lacking.
  • Linguistic studies often require comparing tongue shapes under different articulatory conditions.

Purpose of the Study:

  • To demonstrate the application of smoothing spline ANOVA (SS ANOVA) for comparing tongue curves derived from ultrasound data.
  • To provide a statistical method for determining significant differences in tongue shapes between groups.
  • To illustrate the use of Bayesian confidence intervals for pinpointing specific differences in tongue curves.

Main Methods:

  • Application of smoothing spline ANOVA (SS ANOVA) to compare tongue curves.

  • Utilizing the interaction term in SS ANOVA to detect significant shape differences.
  • Employing Bayesian confidence intervals to identify localized differences between tongue curves.

    • Main Results:

    • The study illustrates how SS ANOVA can identify statistically significant differences between tongue shapes.
    • Demonstrates that the interaction term in SS ANOVA is key to detecting shape variations.
    • Shows that Bayesian confidence intervals effectively localize differences along the tongue curve.

    Conclusions:

    • Smoothing Spline ANOVA (SS ANOVA) offers a robust statistical framework for analyzing ultrasound tongue data in speech research.
    • This method allows for precise identification of articulatory differences between speech conditions.
    • The approach enhances the quantitative analysis of tongue movements in phonetics and speech pathology.
