Study summary

The purpose of the study "A comparison of vocal demands with vocal performance among classroom teachers" is to gather information about the voice production of teachers using three separate strategies: (a) measures of voice assessed with the Computerized Speech Lab (CSL) and the Phonatory Aerodynamic System (PAS) instruments in the SIUC Voice Lab.

What researchers measure

Primary outcomes

  1. Acoustic measures of voice.

    Acoustic measures of voice (i.e., fundamental frequency, total phonation time, and SPL. Participants will be tested three separate times distributed in equal periods throughout one academic semester (i.e., 16 weeks).

    Time frame: 1 year

Secondary outcomes

  1. Identify changes in aerodynamic measures of voice.

    Identify changes in aerodynamic measures of voice (airflow). Participants will be tested three separate times distributed in equal periods throughout one academic semester (i.e., 16 weeks).

    Time frame: 1 year
