Study population: Adult patient >18 years old referred for spirometry in the Respiratory Physiology Clinic at Prince Charles Hospital; Eligibility Criteria - Control Participants Control participants will be contact through the British Lung Foundations local groups who have indicated their willingness to be involved in local clinical research to act as control participants. As all prospective participants will have had their respiratory function measured before taking part by a Respiratory Physiologist, we do not expect to have to screen for medical issues for participation in the study. Furthermore, the actual tests the participants will be undertaking will be non - invasive, submaximal and will require little or no effort.
6.1.2 Inclusion criteria Patient Participants
- Adult patient >18 years old referred for spirometry in the Respiratory Physiology Clinic at Prince Charles Hospital;
- Clinically defined obstructive or restrictive respiratory disease (indicated by spirometry)
- Clinically stable (indicated by being able to undergo spirometry)
- No significant unstable disease co-morbidities (indicated by being able to undergo spirometry)
- Capable of providing informed consent.
- Willing to take part in all study measurements.
- The speaking exercise will be conducted in English on this study.
- Participants are not taking part in any other research. 6.1.3 Inclusion criteria Control Participants
- No obstructive or restrictive respiratory disease (indicated by spirometry) 2. Clinically stable (indicated by being able to undergo spirometry) 3. No significant unstable disease co-morbidity's (indicated by being able to undergo spirometry) 4. Capable of providing informed consent. 5. Willing to take part in all study measurements. 6. The speaking exercise will be conducted in English on this study. 7. Participants are not taking part in any other research.
6.1.4 Exclusion criteria for both Patient and Control Participants

About this study
Official title: Exploring Patterns of Speech and Breathing to Indicate the Presence of Obstructive Disease
Study Title Exploring patterns of speech and breathing to indicate the presence of obstructive respiratory disease.
Study Design Prospective Case Control Study Study Participants Participants will be patients attending the respiratory physiology clinic at the Cardiopulmonary Unit, Prince Charles Hospital for an assessment of their lung function. In addition a cohort of control participants without obstructive respiratory disease will be recruited with the assistance of the British Lung Foundation charity.

Planned Size of Sample (if applicable) We have received funding for 52 ½ day sessions and we plan to recruit on average 2 participants per session. As such we aim to recruit a minimum of 100 participants. In addition we are working with the British Lung Foundation to recruit a smaller Cohort of control participants and aim to recruit a minimum of 25 control participants.
Planned Study Period Jan 2019 - Aug 2019 Research Aim(s) This primary objective of this novel study it to create an anonymised database of speech patterns of patients with chronic respiratory disease and healthy aged matched controls for comparison with lung function and medical history.
The primary aims are to:
- Collect breathing patterns from individuals under a range of talking modalities
- Understand how easy it is to gather short speech recordings
- Explore the preferences of patients to be recorded talking
- Conditions
- COPD
- Being tested
- Speech Recognition
- Medical subject headings
- Pulmonary Disease, Chronic Obstructive

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?
Collect breathing patterns from individuals under a range of talking modalities (time frame: less than 5 minutes). The study lists 3 primary outcomes in all. 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 16 Jul 2026; AzTrials last refreshed its copy on 27 Oct 2026.
