    Area of Science:

    • Biomedical Engineering
    • Speech Science
    • Acoustics

    Background:

    • Traditional cephalostats often rely on earposts for head stabilization, which can be uncomfortable and limit subject movement.
    • Accurate head stabilization is crucial for repeatable measurements in speech production research, particularly when using external transduction devices.

    Purpose of the Study:

    • To describe a novel, low-cost cephalostat for head stabilization.
    • To present a cephalostat design that does not require earposts.
    • To enable voluntary subject evacuation during experiments.

    Main Methods:

    • The study describes the design and construction of a novel cephalostat.
    • The device utilizes external mounting for speech transduction equipment.
    • The cephalostat allows for subject-initiated cessation of the experiment.

    Main Results:

    • The developed cephalostat provides effective head stabilization without earposts.
    • The design is cost-effective to construct.
    • The device facilitates voluntary subject evacuation, improving subject comfort and experimental flexibility.

    Conclusions:

    • The novel cephalostat offers a practical, affordable, and user-friendly alternative for head stabilization in speech production research.
    • This device enhances the feasibility of studies employing external lip and jaw transduction devices.
