This study introduces functional data analysis techniques to understand complex vocal tract movements during speech. These methods help analyze multivariate speech data, revealing insights into articulator coordination and control mechanisms.

Area of Science:

  • Speech science
  • Linguistics
  • Data analysis

Background:

  • Speech production involves complex articulator movements.
  • Understanding these movements is crucial for fields like speech recognition and pathology.
  • Multivariate data from speech experiments pose analytical challenges.

Purpose of the Study:

  • To describe techniques for analyzing multivariate functional data from speech movements.
  • To partition articulator movement data for detailed analysis (e.g., end effects, syllable effects).
  • To apply functional data analysis to understand speech production coordination.

Main Methods:

  • Application of functional data analysis techniques.
  • Utilizing functional counterparts of familiar multivariate procedures (e.g., ANOVA, PCA).

  • Analysis of speech movement data, including acceleration.

    • Main Results:

    • Functional data analysis provides effective tools for describing speech movement data.
    • Identified important sources of variation in lip motion.
    • Analysis of acceleration data suggested potential speech control mechanisms.

    Conclusions:

    • Functional data analysis is well-suited for analyzing complex speech production phenomena.
    • The developed techniques aid in understanding the basic principles of speech coordination.
    • These analytical tools have potential for broader applications beyond speech science.
