We present a new German speech dataset and conduct a pilot study to show the feasibility of using speech to distinguish between decompensated and recompensated ADHF.

Our feature analysis shows a reduction in breathiness and an increase in articulation stability during recompensation. Overall, our results show the promise of speech analysis in the monitoring of ADHF and demonstrate that further efforts should be invested to obtain large-scale data and replicate our results in more heterogeneous populations.\n                  <\/jats:p>","DOI":"10.3389\/fdgth.2026.1885715","type":"journal-article","created":{"date-parts":[[2026,8,12]],"date-time":"2026-08-12T05:55:57Z","timestamp":1786514157000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Speech analysis for acute decompensated heart failure: reporting a pilot study in Germany"],"prefix":"10.3389","volume":"8","author":[{"given":"Andreas","family":"Triantafyllopoulos","sequence":"first","affiliation":[{"name":"Chair of Health Informatics (CHI), University Hospital of the Technical University of Munich","place":["Munich, Germany"]},{"name":"Munich Center for Machine Learning (MCML)","place":["Munich, Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wolfgang","family":"Mayr","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Respiratory Medicine and Intensive Care, University Hospital Augsburg","place":["Augsburg, Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anton","family":"Batliner","sequence":"additional","affiliation":[{"name":"Chair of Health Informatics (CHI), University Hospital of the Technical University of Munich","place":["Munich, Germany"]},{"name":"Munich Center for Machine Learning (MCML)","place":["Munich, Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lana","family":"Lempkens","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Respiratory Medicine and Intensive Care, University Hospital Augsburg","place":["Augsburg, Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bj\u00f6rn W.","family":"Schuller","sequence":"additional","affiliation":[{"name":"Chair of Health Informatics (CHI), University Hospital of the Technical University of Munich","place":["Munich, Germany"]},{"name":"Munich Center for Machine Learning (MCML)","place":["Munich, Germany"]},{"name":"Group on Language, Audio, & Music (GLAM), Imperial College London","place":["London, United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas M.","family":"Berghaus","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Respiratory Medicine and Intensive Care, University Hospital Augsburg","place":["Augsburg, Germany"]},{"name":"Medical Faculty, Ludwig Maximilians University of Munich","place":["Munich, Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,8,12]]},"reference":[{"key":"B1","first-page":"510","article-title":"Acute decompensated heart failure: contemporary medical management","volume":"36","author":"Joseph","year":"2009","journal-title":"Tex Heart Inst J"},{"key":"B2","first-page":"419","article-title":"Defining heart failure","volume-title":"Cardiovas.
