Acoustic measures (fundamental frequency, jitter, shimmer) were generally unchanged, while multiple studies reported reduced maximum phonation time (MPT) during pregnancy. Subjective voice measures tended to worsen, and singer studies reported reduced vocal range and timbre changes. Physiologic studies noted increased vocal fold edema and reduced motility, most prominent in the third trimester. Mechanistic models supported hormone\u2010associated mucosal changes and altered laryngeal protein expression.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The literature on voice changes during pregnancy is limited and heterogeneous, with evidence concentrated in late pregnancy.
