Long-term respiratory illnesses like Chronic Obstructive Pulmonary Disease (COPD) and Asthma are commonly diagnosed with the gold standard spirometry, which is a lung health test that requires specialized equipment trained healthcare experts, making it expensive difficult to scale.Moreover, blowing into spirometer can be quite hard for people suffering from pulmonary illnesses.To solve aforementioned limitations, we introduce MMLung, an approach leverages information obtained multiple audio signals by combining tasks different modalities performed on microphone of smartphone estimate function.Our proposed achieves best mean absolute percentage error (MAPE) 1.3% cohort 40 participants.Compared reported performances (5%-10% MAPE) estimation using smartphones, MMLung shows practical viable utilizing modalities.
