Brief Summary

Human speech is as unique as a fingerprint and analysing speech had advanced so much that speech can now be used instead of PIN numbers in banking. The investigators want to find out whether changes in everyday speech can signal the worsening of asthma. The investigators are planning to collect voice samples from people as their asthma gets better and worse in order to analyse the changes in voice quality - if any. The participants donating the voice samples will remain anonymous and the voice files will be transferred securely to our analytic system.
