Disclosed are an apparatus and a method for determining the state of pulmonary congestion by using artificial intelligence analysis. The apparatus for determining the state of pulmonary congestion by using artificial intelligence analysis, according to an embodiment, may comprise: a data reception unit that receives speech data from a user; a data preprocessing unit that extracts, from the received speech data, partial speech data corresponding to a portion of the speech data by using windowing processing, and converts the extracted partial speech data into a spectrogram; and a pulmonary congestion state determination unit that outputs, by using the spectrogram and a neural network-based pulmonary congestion state determination model, determination data including pulmonary congestion state information about the user.
