Brief summary

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
