Cough is the most common symptom of pneumonia. One of the objective indicators for assessing cough is its sound. Objective. To determine the significance of spectral analysis of cough sounds in patients with pneumonia. Materials and Methods. A systematic review of more than 80 publications was conducted to assess the potential of spectral analysis of cough sounds for the diagnosis of pneumonia and other respiratory diseases. The sources of information included peer-reviewed domestic and international publications indexed in the eLibrary and PubMed databases from 2000 to 2024.The inclusion criteria for the review were as follows: Publications containing information on methods of recording and spectral analysis of cough sounds in patients with confirmed pneumonia of various etiologies; Articles published in English or Russian; Studies involving at least 50 patients with confirmed pneumonia; Research focused on the application of artificial intelligence, machine learning algorithms, and neural networks in the analysis of cough sounds. Results and Conclusion. Spectral analysis of cough sounds using signal processing methods can serve as a supplementary rapid diagnostic tool and assist in the differential diagnosis of productive and dry cough. It also enables the identification of bronchial asthma (BA), chronic obstructive pulmonary disease (COPD), COVID-19, whooping cough, and pneumonia, and holds significant prognostic value.&lt;/p&gt;</abstract><kwd-group xml:lang="en"><kwd>pneumonia, cough, spectral analysis, cough sounds.</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>пневмония, кашель, спектральный анализ, звуки кашля</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
