    Summary

    This study analyzes the control quality in articulation systems, considering nonlinearities. It suggests that auto-oscillations in these systems may contribute to certain forms of stammering.

    Area of Science:

    • Speech motor control
    • Control systems engineering
    • Biomedical engineering

    Context:

    • Articulation control systems exhibit nonlinearities like dead zones, saturation, and logarithmic receptor responses.
    • Understanding these nonlinearities is crucial for evaluating control quality.

    Purpose:

    • To analyze the control quality within the autonomic contour of articulation control systems.
    • To investigate the role of nonlinearities in system stability and auto-oscillation.

    Summary:

    • Nonlinearities including dead zones, saturation, and logarithmic receptor responses were analyzed in articulation control systems.
    • Regions of stability and auto-oscillation frequency were determined, with recontrolling value identified as a key quality criterion.
    • The study proposes a link between auto-oscillations in the articulation control system and the mechanisms underlying some forms of stammering.

    Impact:

    • Provides insights into the control dynamics of speech production.
    • Suggests potential mechanisms for speech disorders like stammering.
    • Offers a framework for assessing and potentially improving articulation control systems.
