What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Experimental group. | Participants are either student teachers or practicing teachers. | |
| Control Group. | Participants are no students teachers or practicing teachers. |
What is being measured
The primary outcome is the main question the study is designed to answer.
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).
Measured: 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).
Measured: 1 year

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Acoustic measures of voice. (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Mar 2021.
